Abstract
The Light Precipitation Validation Experiment (LPVEx) is planned for the Gulf of Finland in September-October 2010. LPVEx is a collaboration between NASA CloudSat, NASA Global Precipitation Mission Ground Validation program, University of Helsinki, FMI and Environment Canada. The goal of the experiment is characterizing the potential for CloudSat cloud radar, the GPM dual-frequency precipitation radar and passive microwave sensors to detect light precipitation and evaluate their estimates of rainfall intensity in high latitude, shallow freezing level environments.
The experiment will take place in the Helsinki Testbed area. It is planned that University of Wyoming King Air aircraft, equipped with particle probes and W-band cloud radar, will be used during the experiment. In addition to ground based instrumentation that is present within the testbed, three dual-polarization C-band radars will be available for the experiment. Two sites, one coastal and one inland, with extensive ground based instrumentation, i.e. 2D-video and Parsivel disdrometers, snow water equivalent sensors, and all weather precipitation gauges, will also be established.
In the presentation we will cover in more detail the above mentioned topics and present updated status of the experiment. The purpose of this presentation is to advertise the experiment among a broader scientific audience.
