Title:  ATMOSPHERIC DEPOSITION ESTIMATES FOR TOTAL NITROGEN (IWI 1.3)
Abstract:  
To collect data on the chemistry of precipitation for monitoring of geographical and temporal long-term trends. The precipitation at each station is collected weekly according to strict clean-handling procedures. It is then sent to the Central Analytical Laboratory where it is analyzed for hydrogen (acidity as pH), sulfate, nitrate, ammonia, chloride, and base cations (such as calcium, magnesium, potassium and sodium)

1)   Objective:  NO DATA PROVIDED
Background:  TO COLLECT DATA ON THE CHEMISTRY OF PRECIPITATION FOR MONITORING OF GEOGRAPHICAL AND TEMPORAL LONG-TERM TRENDS. THE PRECIPITATION AT EACH STATION IS COLLECTED WEEKLY ACCORDING TO STRICT CLEAN-HANDLING PROCEDURES. IT IS THEN SENT TO THE CENTRAL ANALYTICAL LABORATORY WHERE IT IS ANALYZED FOR HYDROGEN (ACIDITY AS PH), SULFATE, NITRATE, AMMONIA, CHLORIDE, AND BASE CATIONS (SUCH AS CALCIUM, MAGNESIUM, POTASSIUM AND SODIUM)

QUALITY ASSURANCE
Data Use / Constraints:  NOTES ON INTERPRETING THIS INFORMATIONTHERE ARE APPROXIMATELY 200 SITES WITH ATMOSPHERIC DEPOSITION ESTIMATES, MEASURED IN KILOGRAMS PER HECTARE PER YEAR. IN ORDER TO INTERPOLATE AND EXTRAPOLATE TO THE 2,111 WATERSHEDS IN THE CONTERMINOUS US, VARIOUS GEO-SPATIAL TECHNIQUES WERE TESTED. THE METHOD THAT WAS SELECTED IS CALLED KRIGING.IN ESSENCE, THE KRIGING ESTIMATES BY WATERSHED CONSTITUTE A MODEL OF THE NITROGEN DEPOSITION BASED ON THE ORIGINAL 200 SITE VALUES. THE VALUES FOR EACH HUC WERE DETERMINED BY USING THE KRIGING CONTOURED VALUE AT THE HYDROLOGIC CENTROID OF THE HUC. THE HYDROLOGIC CENTROID WAS COMPUTED AS THE AVERAGE LAT/LON COORDINATE FROM RF2. RESULTS OF A JACK-KNIFE ERROR ANALYSIS WERE:MEAN ERROR OF 0.011 KG/HA/YRSTANDARD ERROR OF THE ESTIMATE 0.07 STANDARD DEVIATION OF THE ESTIMATES OF 0.935 PLANS TO IMPROVE THIS LAYER 1. CONSIDERATION OF PARAMETERS IN ADDITION TO TOTAL NITROGEN. 2. REFINEMENT OF STATISTICS DEFINING THE DATA SUFFICIENCY (I.E. QUALITY) BY WATERSHED. 3. POTENTIALLY DRAWING RELATIONSHIPS BETWEEN ATMOSPHERIC DEPOSITION OF NUTRIENTS TO SURFACE WATER QUALITY.
