GPM and Cloudsat Researchers Meet in Helsinki to Discuss LPVEx Data

GPM and CloudSat ground validation researchers are currently meeting at the University of Helsinki to discuss  strategies for analyzing airborne and ground-based datasets from the Light Precipitation Validation Experiment (LPVEx) field campaign. This data analysis will help improve satellite-based precipitation retrievals in high latitude light rain and snowfall events.

During the GPM pre-launch period physically-based snowfall retrieval algorithms are in an active phase of development. Further refinement and testing of these emerging algorithms requires the collection of targeted ground-validation datasets in snowing environments. This document describes a field campaign effort designed to provide both new datasets and physical insights related to the snowfall process- especially as they relate to the incorporation of appropriate physics into GPM snowfall retrieval algorithms.

Light Precipitation Validation Experiment (LPVEx) Science Plan

The Light Precipitation Evaluation Experiment (LPVEx) planned for the Gulf of Finland in September and October, 2010 will seek to address this shortcoming by collecting microphysical properties, associated remote sensing observations, and coordinated model simulations of high latitude precipitation systems to drive the evaluation and development of precipitation algorithms for current and future satellite platforms.
