GPM Ground Validation Canadian CloudSat/CALIPSO Validation Project (C3VP)

Location of C3VP CARE site (red dot) in Ontario, Canada.The Global Precipitation Measurement mission Ground Validation (GPM GV) campaign used a variety of methods for validation of GPM satellite constellation measurements prior to and after launch of the GPM Core Satellite, which launched on February 27, 2014. The instrument validation effort included numerous GPM-specific and joint agency/international external field campaigns, using state of the art cloud and precipitation observational infrastructure (polarimetric radars, profilers, rain gauges, and disdrometers). These field campaigns accounted for the majority of the effort and resources expended by GPM GV (Ground Validation) mission. More information about the GPM mission is available on the Precipitation Measurement Mission (PMM) Ground Validation webpage.

The Canadian CloudSat/CALIPSO Validation Project (C3VP) was an collaborative international field campaign that took place in southern Canada during the 2006/2007 winter season. With the help of multiple organizations, including the NASA GPM and PMM science teams, the campaign used various ground-based and airborne instrumentation to thoroughly study cold season precipitation systems and therefore improve the modeling and remote sensing of snowfall. The campaign took place in the vicinity of the Centre for Atmospheric Research Experiments (CARE) in the Great Lakes region of Ontario, Canada. The site was operated by the Meteorological Service of Canada (MSC). The main objectives of the campaign were to capture more ground and airborne observations of winter precipitation, to validate data from the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) and NASA CloudSat satellites, and to further improve the remote sensing and modeling of winter precipitation. More information about the C3VP field campaign is available on the NASA GPM C3VP webpage.
