This dataset consists of sounding data from aboard the Research Vessel (R/V) Vickers. The R/V was operated jointly by the National Oceanic and Atmospheric Administration (NOAA) and the University of Southern Califoria (USC). The R/V was in TOGA-COARE domain during 90 days of the full 120 day IOP, however soundings were released only during the period from 28 January to 27 February 1993. Soundings were taken four times per day (00, 06, 12 and 18 UTC) during participation in the IOP. UCAR/JOSS conducted no quality control on these data. This dataset includes pressure, temperature, dew point, relative humidity, wind speed, wind direction, and altitude taken at 10 second vertical intervals. Refer to the station README file for details. NOTE: This dataset has been updated (5/2/2002) with corrected data for the humidity measurement errors of the Vaisala RS 80 radiosonde (Wang et al 2002). Please see the README for details.
