PREDICT 2010 Multi-Network Composite Highest Resolution Upper Air Data - ESC Format


This data set is a composite of radiosondes and dropsondes collected from 3 dropsonde and 4 radiosonde platforms during the Pre-Depression INvestigation of Cloud-systems in the Tropics (PREDICT) 2010 project with data collected from 1 August 2010 through 30 September 2010. The PREDICT area of interest is 0 to 45N and 15-100W. This composite contains a total of 3219 soundings at their native resolution. Included are radiosonde data from the GTS Mandatory/Significant Level Sounding Data (1287 radiosondes), Howard University at Barbados (99 radiosondes), Howard University at Cape Verde (20 radiosondes), and from 24 US National Weather Service sites (841 radiosondes). Additionally, dropsonde data are included from the United States Air Force C-130 (86 dropsondes), NSF/NCAR G-V (558 dropsondes), and GRIP NASA DC-8 (328 dropsondes).
