MPEX: NSF/NCAR G-V AVAPS Dropsonde High Resolution Data, CLS format

Summary

The National Center for Atmospheric Research/Earth Observing Laboratory (NCAR/EOL) operated a dropsonde system on-board the NSF/NCAR G-V aircraft during the Mesoscale Predictability Experiment (MPEX) during the period from 15 May to 14 June 2013. Soundings were taken intermittently as determined by the weather situation, with a focus on the pre-convective and convectively disturbed environments near deep convective storms in the central United States. This data set includes a total of 426 quality controlled, high vertical resolution (0.25 second) soundings are contained in the final MPEX data set.

Data Quality	final
Versions	1.0 (2014-03-12) 2.0 (2016-12-21): 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. (Only the current version of the data is available to order. If you have questions about a prior version, please email us.)
