GHRC published the guide document for the GPM Ground Validation Environment Canada (EC) Vaisala Ceilometer GCPEx dataset. The ceilometer data was collected during the GPM Cold-season Precipitation Experiment (GCPEx) in Huronia, Canada from January 15, 2012 through March 1, 2012. The CT25K ceilometer uses pulsed diode laser LIDAR technology to derive backscatter profiles, cloud heights and vertical visibilities. It is also able to detect three cloud layers simultaneously.
