BACKGROUND INFORMATION This data set presents measured values of plant diameter and height, biomass of plant components, and nutrients in vegetation from a study of the effects of carbon dioxide and nitrogen fertilization on ponderosa pine (Pinus ponderosa Dougl. ex. Laws.) conducted in open-top chambers in Placerville, California, from 1991 through 1996. This data set contains values from 1991 through 1993. Further background for the study, as well as the results and conclusions from the study, may be found in Johnson et al. (1997), which is the primary reference for this data set. Users who wish to use these data in specific model exercises or research exercises should first refer to Johnson et al. (1997). 5. EXPERIMENTAL SETUP AND METHODS Detailed information concerning the site and experimental setup, treatments, and sampling and analytical methods is given in Johnson et al. (1997) and Walker et al. (1997); the methods are summarized below. Twenty-four hexagonal open-top chambers, 3.6 m in diameter, were established in February April 1991 at the Institute of Forest Genetics in Placerville, California, on a soil of Aiken clay loam, an andesite-derived Xeric Haplohumult. The studied pines were grown from seeds (21 locations per chamber) planted in May 1991. Treatment began in May 1991. There were three treatment levels of nitrogen (N) fertilization (0, 10, and 20 g N per square meter per year applied as ammonium sulfate) and four CO2 treatments (ambient, no chamber; ambient, chambered; 525 microliters CO2 per liter air; and 700 microliters CO2 per liter air). All combinations of the treatments were studied, except for the combination of 10 g N per square meter per year and 525 microliters CO2 per liter air. Each of the unchambered treatments was replicated twice, each of the chambered treatments thrice. All plots were watered identically. Three trees from each chamber were harvested in October 1991, 1992, and 1993 (including complete root systems for all three harvested trees per chamber in 1991 and 1992 and for one tree per chamber in 1993). Seedlings were dried, weighed by component (foliage, branch, stem, and roots; in 1991 and 1992, branches were sufficiently trivial that their weights were included with those of stems), and analyzed as follows: N: analyzed on a Perkin-Elmer 2400 CHN Analyzer Other nutrients (P, S, K, Ca, Mg, B, Cu, Fe, Mn, Zn): dry-ashed at 550 degrees Celsius for 4 h, dissolved in 5% (v/v) nitric acid, and analyzed by inductively-coupled plasma (ICP) emission spectroscopy In 1992, no elemental analyses were conducted for branches in the unchambered treatment. Tree biomass for needles, stems (including branches), and roots was measured directly in 1991 for the trees analyzed for nutrient concentration. For 1992 and 1993, the following regression was established (based on measured diameters, heights, and biomass), relating biomass in grams for each component (Comp) to diameter (d), measured in mm at 10 cm, and height (h), measured in cm: ln(Comp) = a + (b)ln(d2h), where a and b are regression constants given in the following table: _____________________________________________________________ Component a b r2 _____________________________________________________________ 1992 Harvest Needles -2.9797 0.65540 0.692 Stems + branches -4.8812 0.86967 0.724 Roots -4.9412 0.84429 0.615 1993 Harvest Needles -6.2504 1.0395 0.729 Branches -12.173 1.4685 0.631 Stems -9.4724 1.3200 0.819 Roots -6.7686 1.038 0.868 ______________________________________________________________ Measurements in 1993 were based on one whole tree, plus two additional tree tops, harvested per chamber. The user should note that two sets of height and diameter data are reported for 1993 (in association with the measured nutrient concentration data, and in association with the biomass data used to generate the regressions); the height and diameter measurements used to generate the regressions were taken a short time after the measurements at harvest. In the data files and this documentation, the terms "leaf" and "needle" are equivalents, as are "stem" and "trunk." 6. APPLICATIONS OF THE DATA These data may be used to study the effect of elevated levels of atmospheric carbon dioxide, in combination with various levels of nitrogen fertilization, on the growth and nutrient content of ponderosa pine (Pinus ponderosa Dougl. ex Laws.), an important timber species of western North America. Johnson et al. (1997) used the data documented in this numeric data package to evaluate two hypotheses: (1) that elevated CO2 would increase growth and yield of biomass per unit uptake of N even if N is limiting, and (2) that elevated CO2 would increase biomass yield per unit uptake of other, nonlimiting nutrients only by growth dilution. For several years, research has been conducted on the effects of elevated carbon dioxide, alone or in combination with other factors such as the availability of water and nutrients, on many different wild and cultivated plant species. There has been a trend towards more realistic conditions: from flowerpot studies in growth chambers to open-top chamber studies (the experiment whose data are documented in this numeric data package is one such study), in which the plants are exposed to the atmosphere and in which the roots are not necessarily confined to pots. A further step towards realism was taken in the 1990s with the development of the FACE (Free Air CO2 Enrichment) studies (Ellsworth et al. 1995), in which plants are grown without confinement in chambers and carbon dioxide is typically released around the perimeter of the circular study area (with attention paid to wind speed and direction) in sufficient quantity to maintain desired concentrations of carbon dioxide within the study area. An early review of the literature on the effects of elevated carbon dioxide on vegetation may be found in Strain and Cure (1985), while a recent review may be found in Amthor (1995). Two bibliographies that include much of the pertinent literature are Strain and Cure (1986) and Strain and Cure (1994). Curtis (1997) is an on-line data base that summarizes many studies of the effects of elevated carbon dioxide on woody vegetation. 7. DATA LIMITATIONS AND RESTRICTIONS Users should appreciate that the study whose data are documented in this numeric data package suffers from the inherent limitation common to all open-top chambers studies: the plants are confined in chambers and therefore are not growing in completely natural conditions. For a critique of open-top chamber studies, and descriptions of other experimental approaches for measuring the responses of plants to elevated carbon dioxide, the user is referred to Allen et al. (1992) and Ceulemans and Mousseau (1994). Johnson et al. (1997) have noted that observed declines in soil carbon and nitrogen during the study probably resulted from plowing that occurred before planting, rather than from the experimental treatment. It is possible that some observed changes in plant growth and nutrient content may also have been responses to plowing, rather than to the experimental treatment. That is, preplanting plowing may be considered a potential artifact of the experiment. Users are cautioned against using sample tree averages to estimate treatment effects because that would yield a biased result; that is, the sample trees did not reflect the average dimensions of all trees in the chambers. An unbiased estimate of biomass and nutrient content can be obtained by applying regressions to the diameter and height measurements of all trees in the chambers. 8. REFERENCES Allen, L.H., Jr., B.G.

QUALITY-ASSURANCE CHECKS AND DATA-PROCESSING ACTIVITIES PERFORMED BY CDIAC An important part of the data-packaging process at the Carbon Dioxide Information Analysis Center (CDIAC) is the quality assurance (QA) of the data before their distribution. The QA process is an important component in the value-added concept of ensuring accurate, usable information. The complete QA of a data set can be a time-consuming process, since data received by CDIAC are rarely in condition for immediate distribution, regardless of source. The following summarizes the QA checks and data-processing performed on the data sets presented in this document: 1. The EXCEL (registered trademark of the Microsoft Corporation, Redmond, Washington) spreadsheet files were provided by the principal investigators. 2. Cell formulas contained in the spreadsheets received by CDIAC were checked for correctness using EXCEL and QUATTRO PRO (registered trademark of the Corel Corporation, Ottawa, Ontario, Canada). 3. Values entered directly into the spreadsheets were verified wherever possible by values calculated from data already in the spreadsheets. 4. The files were simplified and reduced to include only direct measurements (of diameter, height, biomass, and nutrient concentrations); estimated values (e.g., biomass calculated from regressions, nutrient content derived from estimated biomass and measured concentration) and statistics were removed. 5. The files for the 1992 and 1993 data were compared with respect to carbon dioxide and nitrogen treatment levels, chamber label, and replicate number, to ensure correctness and consistency of nomenclature. 6. Variables were renamed for internal consistency, with the new names ranging from one to six characters each. 7. Spreadsheet files were reformatted into 1-2-3 (registered trademark of the Lotus Development Corporation, Cambridge, Massachusetts) *.wk1 spreadsheet files and converted into flat ASCII files, in which -9, -9.9, or -9.99 represent missing values. 10. HOW TO OBTAIN THE DATA AND DOCUMENTATION These data may be used with spreadsheet software (e.g., 1-2-3, EXCEL, or QUATTRO PRO) or with other database management and statistical software. The spreadsheets in this data package were saved as both 1-2-3 *.wk1 spreadsheet files and *.dat flat ASCII files. The computerized data are available on Exabyte 8-mm tapes, QIC 1/4" tape cartridges, IBM DOS-compatible floppy diskettes (3.5" or 5.25"), and through CDIAC's World Wide Web site and anonymous File Transfer Protocol (FTP) area (addresses given below).

DESCRIPTION OF THE DOCUMENTATION FILE ndp061a.txt (File 1) This file contains a detailed description of the data base (name of the numeric data package, principal investigators, keywords, background information, experimental setup and methods, applications of the data, data limitations and restrictions, references, QA checks and data-processing activities performed by CDIAC) and how to obtain the data and documentation. A description of the formats, units, and other pertinent information about each file associated with this database is included. 13. DESCRIPTION OF THE DATA FILES DATA FORMAT AND UNITS The data contained in this NDP are available as both 1-2-3 spreadsheet files and flat ASCII files. SAS and FORTRAN programs designed to read each ASCII data file are also provided. In all files, C (carbon dioxide treatment) is defined as follows: 1 = no chamber; 2 = ambient (350 microliters CO2 per liter air); 3 = 525 microliters CO2 per liter air; 4 = 700 microliters CO2 per liter air. N (nitrogen treatment) is defined as follows: 1 = unfertilized; 2 = 10 g N per square meter per year; 3 = 20 g N per square meter per year. Each variable label consists of up to six characters, where BM denotes biomass, BR denotes branch, CC denotes a concentration (mass per unit mass) of a nutrient in plant tissue, CD denotes candle (new shoots where needles have not come out yet), CHBR denotes open-top chamber identification label, CR denotes coarse root [the sum of medium root plus tap root (i.e., diameter >2 mm)], DIA denotes diameter, FO denotes foliage FR denotes fine root (diameter <2 mm), HT denotes height, LF denotes leaf (needle), LR denotes lateral root, MR denotes medium root (diameter from 2 mm to 1 cm), N1 denotes first-flush needle (the first flush of needles in a given year), N2 denotes second-flush needle (the second flush of needles in a given year), NO denotes old needle (needles that appeared before 1993), NS denotes senesced needle (brown needles that were about ready to fall off the tree), REP denotes seedling replicate identification label, RT denotes root, ST denotes stem (includes branches in 1991 and 1992), TB denotes trunk bottom (10 cm from the bottom of the trunk), TM denotes trunk middle (halfway up the trunk), TR denotes tap root, TT denotes trunk top (the middle of the top shoot), and where the standard chemical symbol (in all upper case) is used for elements. The general pattern for indicating nutrient concentrations (i.e., the final two letters are "CC") is that the first two letters indicate the plant tissue, and the following one or two letters indicate the nutrient; thus, "LFMNCC" represents the measured concentration of manganese in leaf tissue. FLAT ASCII DATA FILES The following tables describe the contents and formats of the five flat ASCII files that are distributed with this data package. Missing values are represented by -9.99, with two exceptions: -9 represents missing values of REP in trees91.dat (File 4), and -9.9 represents missing values of HT in regr93.dat (File 3). The data files in this package do not contain any negative values other than the missing-value indicators. The following tables also indicate the column in the corresponding spreadsheet files in which each variable is found. For trees92.dat (File 5), the user should note that, for the sake of consistency of format, all data in columns >35 are shown with an apparent precision of two digits to the right of the decimal (i.e., hundredths of the specified unit); for trees93.dat (File 6), this applies to all data in columns >42. This should not be construed as the true precision of measurement; for many variables the user will observe only zeros to the right of the decimal (other than in the case of -9.99, the missing-value indicator). The user is strongly urged to pay careful attention to the variable widths specified in the following tables and in the FORTRAN and SAS data retrieval programs provided with this package (*.for and *.sas, respectively). In some cases (i.e., where values occupy all the allotted six or seven spaces), adjacent values will run together, and there will be no space between adjacent values. Therefore, importing the data into a program with space or tab delimiters would produce erroneous results. It is highly recommended that the *.wk1files provided with this data package be used for spreadsheet applications. Table 2.
