Ground Validation

Content related to ground validation activities and field campaigns.

Document Description

In support of NASA PMM, observations collected near Darwin, Australia, have been processed and data sets are being provided to the NASA PMM community to help validate and improved satellite retrieval algorithms and cloud resolving models.

The data sets are derived from surface rain gauges, a disdrometer, and vertical pointing profilers deployed at the Australian Bureau of Meteorology Research Centre (BMRC) wind profiler site near Darwin, Australia during the Tropical Western Pacific – International Cloud Experiment (TWP-ICE).

Document Description

The Global Precipitation Measurement mission (GPM) Ground Validation (GV) Science Implementation Plan (GVSIP) applies three overarching approaches to validation of GPM satellite constellation measurements, products, and algorithms. These approaches include:

Document Description

This document provides a basic set of documentation for the data products available from the GPM Ground Validation System (GVS) Validation Network (VN). In the GPM era the VN performs a direct match-up of GPM’s space-based Dual-frequency Precipitation Radar (DPR) data with ground radar data from the U.S. network of NOAA Weather Surveillance Radar-1988 Doppler (WSR-88D, or “NEXRAD”). Ground radar networks from international partners are also part of the VN.

Document Description

Science plan for the Mid-Continent Convective Clouds Experiment (MC3E), scheduled for the spring of 2011. This campaign will be conducted in cooperation with the Department of Energy's (DoE) Atmospheric Radiation Program (ARM). The field campaign will be conducted in south-central Oklahoma. The goal of the campaign is to contribute to the improvement of radar and microwave precipitation retrieval algorithms over land.

Dual-frequency Dual-polarized Doppler Radar (D3R)

The D3R will operate as part of GPM Ground Validation, supporting GPM pre-launch algorithm development and will contribute to post-launch precipitation product validation. In the pre-launch era, the D3R provides independent estimation of hydrometeor classification and drop size distribution retrievals. The radar thus offers an insight into the microphysical processes that dominate the retrieval (and associated measurement error) of precipitation types and rates from satellite data.
