IPMSI Precipitation Validation

Increasing Participation of Minority Serving Institutions in Earth Science
Division Surface-Based Measurement Networks

In 2021, NASA Heaquarters (HQ) issued a Research Opportunities in Space and Earth Sciences (ROSES) opportunity to address "Increasing Participation of Minority Serving Institutions (MSI) in Earth Science Division Surface-Based Measurement Networks". The goal was to provide ground-based instruments to MSI in order to better engage these communities in NASA Earth Science Division (ESD) Science, Technology, Engineering and Math (STEM) activities. A total of 22 proposals were submitted, from which 15 were selected for funding.

The call was to provide one or more ground-based platforms consisting of AERONET, PANDORA and Precipitation Stations. The Precipitation Stations, which we discuss here, are being provided by the GPM Ground Validation program, and consists of a pair of rain gauges and for some a Parsivel Disdrometer. Of the 15 selected sites, eight chose the precipitation systems. The gauge-only systems are referred to as Platforms for In situ Estimation of Rainfall Systems (PIERS), while the gauge + disdrometer systems are referred to as PIERS+.

Precipitation Validation Network

The map above illustrates the selected MSIs. The institutions that requested PIERS systems are denoted with yellow circles and the sites denoted by the yellow squares denotes PIERS+ systems.
