MPEX: Multi-Network Composite Highest Resolution Upper Air Data


This data set contains a composite of the highest resolution (i.e. the “native” resolution) upper air sounding data from all sources for the Mesoscale Predictability Experiment (MPEX). Sounding data is included from nine sources: the National Weather Service (23 sites and 1484 soundings), the dropsondes from the NSF/NCAR G-V aircraft (426 soundings), the Atmospheric Radiation Measurement (ARM) Central Facility site (123 soundings), Vandenberg Air Force Base (31 soundings), and soundings from MPEX mobile sounding systems operated by Colorado State University (55 soundings), the National Severe Storms Laboratory (111 soundings), Purdue University (94 soundings), and Texas A&M University (23 soundings). Included are 2347 soundings from 30 platforms from 10 May to 16 June 2013.

Data Quality final
  • 1.0 (2014-07-21)
  • 2.0 (2017-01-06):

    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.)
