PREDICT: Multi-Network Composite 5mb Level Upper Air Data


This data set is a composite of radiosondes and dropsondes collected from 3 dropsonde and 3 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 0-45N and 15-100W. This composite contains a total of 1932 5mb resolution soundings. Included are radiosondes from the Howard University at Barbados (99 radiosondes), Howard University at Cape Verde (20 radiosondes), and from 24 US National Weather Service sites (841 radiosondes). Also included are dropsondes from the United States Air Force C-130 (86 dropsondes), NSF/NCAR G-V (558 dropsondes), and GRIP NASA DC-8 (328 dropsondes). This data set contains upper-air sounding data interpolated to a constant vertical resolution of 5 hPa in the National Center for Atmospheric Research (NCAR) Earth Observing Laboratory (EOL) Sounding Composite Format. All soundings were quality controlled by NCAR/EOL.

Data Quality final
  • 1.0 (2012-05-30)
  • 2.0 (2017-04-11):

    This version corrects a temperature dependent dry bias that was present in the Vaisala RD94 dropsonde relative humidity measurements. Both the relative humidity and dew point values have been corrected.
