The Canadian CloudSat/CALIPSO Validation Programme (C3VP) took place during winter 2006-2007. The C3VP sought to evaluate snowfall science and algorithms for CloudSat and CALIPSO. C3VP included airborne and ground-based observations of snow in the vicinity of the Centre of Atmospheric Research Experiments (CARE) site in south-east Ontario, Canada operated by the Meteorological Service of Canada. A secondary objective of C3VP was to collect data for pre-launch development of snowfall algorithms for the Global Precipitation Measurement (GPM) mission. The campaign was a collaborative effort between NASA, Canada’s National Research Council (NRC), Environment Canada (EC), and the Colorado State University (CSU).
