alcf stats
alcf stats - calculate cloud occurrence statistics
Usage: alcf stats <input> <output> [<options>]
Arguments:
input: input filename or directoryoutput: output filename or directory
Options:
blim: <value>: backscatter histogram limits (1e-6 m-1.sr-1). Default:{ 5 200 }.bres: <value>: backscatter histogram resolution (1e-6 m-1.sr-1). Default:10.filter: <value> | { <value> ... }: Filter profiles by condition:cloudyfor cloudy profiles only,clearfor clear sky profiles only,nightfor nighttime profiles,dayfor daytime profiles,nonefor all profiles. If an array of values is supplied, all conditions must be true. Fornightandday, lidar profiles must contain valid longitude and latitude fields set via thelonandlatarguments ofalcf lidaror read implicitly from raw lidar data files if available (mpl, mpl2nc). Default:none.tlim: { <start> <end> }: Time limits (see Time format below). Default:none.zlim: { <low> <high> }: Height limits (m). Default:{ 0 15000 }.zres: <value>: Height resolution (m). Default:50.bsd_lim: { <low> <high> }: backscatter standard deviation histogram limits (1e-6 m-1.sr-1). Default:{ 0.001 10 }.bsd_log: <value>: enable/disable logarithmic scale of the backscatter standard deviation histogram (trueorfalse). Default:true.bsd_res: <value>: backscatter standard deviation histogram resolution (1e-6 m-1.sr-1). Default:0.001.bsd_z: <value>: backscatter standard deviation histogram height (m). Default:8000.
Time format:
“YYYY-MM-DD[THH:MM[:SS]]”, where YYYY is year, MM is month, DD is day, HH is hour, MM is minute, SS is second. Example: 2000-01-01T00:00:00.
Examples:
Calculate statistics from processed lidar data in alcf_cl51_lidar
and store the output in alcf_cl51_stats.nc.
