Summary
DATA ACCESS
The soundings data are available through the WWW (World Wide
Web)/CODIAC interface at http://www.joss.ucar.edu/codiac/ .

Priority Sounding Station (PSS) log files are available via anonymous
FTP from Florida State University, Center for Atmospheric Prediction
Studies.

TOGA COARE BACKGROUND

TOGA COARE was a ... multidisciplinary, international research effort that
investigated the scientific phenomena associated with the interaction
between the atmosphere and the ocean in the warm pool region of the
western Pacific. The field experiment phase of the program took place
from 1 November 1992 through 28 February 1993 and involved the
deployment of oceanographic ships and buoys, several ship and land
based Doppler radars, multiple low and high level aircraft equipped
with Doppler radar and other airborne sensors, as well as a variety of
surface based instruments for in situ observations.

I. HIGH RESOLUTION SOUNDINGS DATA AT UCAR/JOSS

TOGA COARE high resolution sounding data for the Priority Sounding
Station (PSS) network were made available by the UCAR/Joint Office for
Science Support (JOSS). This release includes the online availability
of the soundings for 37 PSS sites including six research vessels. Any
gaps in the high resolution sounding data were filled by sounding data
from the GTS archives at BoM, Australia and ECMWF, when
available. This dataset is the most complete, high-resolution
upper-air sounding dataset for the equatorial Pacific region.

The soundings are in native resolution and are available in Bufr,
EBufr, NetCDF, and ASCII (CLASS) formats. Also available online are
documentation files for each site that describe, in some detail, the
site-specific processing conducted at JOSS, as well as information on
the release location, availablity of soundings, radiosonde
information, and information on the raw data files (available
offline).

For more information, contact James Moore at UCAR/JOSS
(jmoore@ncar.ucar.edu).


II. PSS LOGS

Meteorological surface data were recorded by local operators at all
PSS sites in so-called log-sheets. These logs are available in ASCII
format and include the following 11 fields:

+ Julian day between 1 and 366 (1992 was a leap year).
+ Four-character GMT time of observation, hhmm (hours and minutes).
+ Pressure: in millibars, one decimal.
+ Dry bulb temperature: C degrees, one decimal.
+ Wet bulb temperature: C degrees, one decimal.
+ Dew point temperature: C degrees, one decimal.
+ Relative humidity: %, no decimal.
+ Wind direction: 1 to 3 letters (N,E,S,W).
+ Wind speed: knots, no decimal.
+ Visibility: 1 to 2 digits (km).
+ Present weather: 1 to 2 digits (WMO code number).

Priority Sounding Station (PSS) log files are available via anonymous
FTP from Florida State University, Center for Atmospheric Prediction
Studies.


III. MANUS ISLAND MINI SODAR AND AWS DATA

AWS and mini SODAR surface meteorological data were collected on Manus
Island at the Momote airport. The AWS recorded surface meteorological
parameters such as pressure, temperature, winds, radiation, and
humidity in five-minute intervals from 12 January to 8 February
1993. The humidity data are unreliable before 28 January due to an
outdated humidity sensor. The data of each block are composed of 3-D
winds observed every 15 minutes from the ground level of the antenna
located at 2.7 m elevation up to 1000 m in 50-meter intervals. The
time for each data block was recorded in local standard time at the
end of each 15-minute observation period.

(ghlim@allinat.snu.ac.kr).

Quality
Quality Control at JOSS:
The data have passed through the Quality Control process after
the original data were converted into the JOSS Quality Control (ASCII)
Format (QCF). Data were processed, quality controlled and archived in
the highest "native" resolution. The time resolution of PSS data
varied from 2 seconds to 60 seconds. All steps in the QCF ... generation
process were documented and made available to the users for
assessment. JOSS' QC process consists of three stages:

a) automatic internal consistency checks, which include 17 automatic
checks to evaluate the internal consistency of each individual
sounding ("reasonable limit" check);

b) vertical consistency checks which include comparisons between
adjacent vertical levels;

c) visual examination of each sounding. To establish the consistency
of upper air measurements across the entire COARE domain, spatial
quality of the sounding data was assessed by comparing neighboring
data. The general methodology used by JOSS is to produce statistics
(mean, standard, deviation, variance) from a simple weighted averaging
technique.

JOSS generated or gathered several data and documentation files for
each sounding location.

In addition to the actual data (native format and 5 hPa interpolated
sounding data), derived sounding parameters, site-by-site processing
and QC documentation, statistics generated from the spatial QC and
user-generated GIF imges for selected data are available.
