met_zm

Extract zonal mean from meteorological data.

The calling sequence is:

# calling met_zm
$ ./met_zm  <ctl> <zm.tab> <met0> [<met1> ...]

The required arguments are: * ctl: The file containing the control parameters. * zm.tab: The output file where the zonal means are stored. * met0 [\<met1> ...]: The meteorological input files from which the zonal mean should be calculated.

Example control-file settings for creating a global zonal mean with a latitude band width of 10 degrees from ERA5 data:

ZM_DLAT = 10

Example call:

./met_zm zm.ctl zm_era5_2017_01_08_17_1_1.tab era5_2017_01_08_17.nc

The optional control parameters required are listed as follows:

parameter	purpose	default
ZM_Z0	Altitude range start [km]	-999
ZM_Z1	Altitude range end [km]	-999
ZM_DZ	Altitude interval [km]	-999
ZM_LON0	Longitude range start	-180
ZM_LON1	Longitude range end	180
ZM_LAT0	Latitude range start	-90
ZM_LAT1	Latitude range end	90
ZM_DLAT	Latitude interval	-999

Note: if ZM_DZ, ZM_Z0, ZM_Z1 are not defined, the output dimension of altitude will follow the meteorological data.
