Rain Gauge: GPM Precipitation Science Research Facility

Wallops PRF High-Density Gauge Network

The Wallops GPM PRF is currently supporting multiple gauge and disdrometer networks. A high density gauge grid is located in an around Pocomoke City, MD is aimed towards validating space-based estimates on the scale of the nominal GPM DPR footprint size of about 5 km.

The second, larger grid, also includes the Pocomoke network, but it's scale is approximately 0.5 degrees (lat & lon). This network will serve to better validate both DPR and GMI observations and is well sampled by NASA's NPOL radar, which is located in Newark, MD. The 0.5 degree scale is roughly bounded by Chincoteague, VA to the southeast; Crisfield, MD to the southwest; Salisbury, MD to the north; and, Newark, MD to the northeast.

GPM is also supporting NASA's Improved Participation of Minority Serving Institution (IPMSI) in STEM research. We have deployed gauges and disdrometer at several MSI' in New York, Maryland, Virginia, Louisiana, Texas and Arizona. Click here to visit our IPMSI pages.
