CFMIP_LidarRadar

This script creates a figure of zonal cloud and hydrometeor plots comparing COSP Lidar and Radar simulator output with CALIPSO-GOCCP and CloudSat observations.

The zonal plots show cloud fraction as determined by the lidar in CALIPSO GOCCP observations, model with lidar simulator and the model itself. Similarly, the hydrometeor fraction as determined by CloudSat and the radar simulator.

Model Input Variables

Unfortunately, due to file size and availability, no supplementary data will be provided for this script. Please note that within the NCL script, all IPSL+simulator files AND variable names must be replaced. The Model files listed below are merely an example of which variables are needed to create the plots.
