USAF C-130 NCAR/EOL Dropsonde High Resolution Data

Project:

ITOP

Summary

During ITOP 2010 two USAF C-130 aircraft deployed EOL/AVAPS Dropsondes in 26 flights over the Western Pacific Ocean during the months of August, September, and October 2010. This data set includes the high resolution (0.25 second winds and 0.5 second pressure, temperature and humidity) USAF C-130 dropsonde data set in the EOL columnar ASCII sounding format. This data set has undergone NCAR/EOL quality control. See the readme for details on the QC process and data quality issues.
