Mesoscale Predictability Experiment (MPEX)

The Mesoscale Predictability Experiment (MPEX) was conducted within the U.S. intermountain region and high plains during the late spring/early summer of 2013 and included the use of the NSF/NCAR GV, along with the new Airborne Vertical Atmospheric Profiling System (AVAPS) dropsonde system and the Microwave Temperature Profiling (MTP) system, as well as several ground-based mobile upsonde systems, for the field experiment which took place during a 4-week time period from 15 May to 15 June 2013. MPEX was motivated by the basic question of whether experimental, sub-synoptic observations could extend convective-scale predictability and otherwise enhance skill in regional numerical weather prediction over a roughly 6 to 24 hour time span.
