This instrument is a vertical profiler radar that delivers information about structure in the atmospheric column and enables scientists to estimate the vertical distribution of rainfall. At all times of the day, light rainfall is the dominant type of precipitation.
Light rainfall is the most reliable and most frequent form of rainfall in the region, contributing 50 to 60 percent of the total precipitation over a year. Light rain is no less than the lifeline of freshwater resources for the landscape’s ecosystems.
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.
