Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published the GPM Ground Validation Aerosol and Water Vapor Lidar Quicklooks GCPEx dataset in the Global Precipitation Monitoring (GPM) mission Ground Validation collection for the GPM Cold-season Precipitation Experiment (GCPEx). This dataset contains imagery generated from the GCPEx campaign during January - March 2012 in Canada. Imagery includes plots of daily aerosol lidar backscatter ratio, and vertically resolved profile of water vapor mixing ratios. DOI: http://dx.doi.org/10.5067/GPMGV/GCPEX/LIDAR/DATA101
