Short Name:


The GRIP Barbados/Cape Verde radiosonde data set consists of generally two soundings per day (06Z and 12Z) launched from Barbados, and one sounding per day (12Z) launched from Cape Verde during the Genesis and Rapid Intensification Processes (GRIP) field campaign. The major goal was to better understand how tropical storms form and develop into major hurricanes. These radiosondes measure the profile of atmospheric pressure, temperature, humidity, wind speed and direction, from the ground to an altitude of up to 40 km (in general, the sondes reached at least a pressure of 100 milibars). The launch program began on August 14, 2010 and ended September 24, 2010. The sondes used were type DFM-06, built by GRAW Radiosondes, Nuremberg Germany. Most ascents were done with TOTEX 200-g latex balloons using the DMF-06 sondes. A few launches were made using TOTEX 800-g Balloons with the DFM-97 package (connected with ECC ozonesonde). On some days launch times were changed, and multiple launches were made from Barbados on September 9, 10 and 21. The data were retrieved using a GRAWMET GS-E ground station. The sample rate of the data was 4 seconds for the Barbados data and 2 seconds for the Cape Verde data.
