CSU TOGA COARE SOUNDING DATA ARCHIVE


Introduction


TOGA COARE was an international coupled ocean-atmosphere experiment conducted in the tropical western Pacific during the period November 1992 through February 1993. Colorado State University participated in this experiment principally through the operation of the atmospheric sounding network (PI: Prof. Richard H. Johnson) and the ship-based radar network (PI: Prof. Steven A. Rutledge). This soundging data web site contains information concerning data collected from TOGA COARE Priority Sounding Sites and the NCAR/NOAA wind profilers.

The data sources listed below represent various levels of processing of the raw sounding data (available from UCAR's JOSS). They include merged sounding and 915 MHz wind profiler data as well as objectively analyzed and gridded analyses.

It is extremely important to emphasize that most of the data sets listed are evolutionary. Namely, we are continually working to improve the quality of the data as new information becomes available. Therefore, we urge you to keep abreast of updates by registering your use of the datasets with us (see contact person at bottom of this page). As an example, during Summer 1997 a major effort is underway to correct and improve the reported humidity values from the COARE soundings. When a consensus is reached on a set of corrections, we will add a revised dataset to the inventory.



As of March 2002, we have reprocessed the LSA-gridded analyses using the humidity corrected data (V2 LSA Gridded Analyses). Also on April 26, 2002 we released the V2 IFA-averaged dataset. The following recent publication is related to the humidity corrections:
