llbox : extract a latitude-longitude box¶
Extract a lat-lon domain using CDO
References : https://code.zmaw.de/projects/cdo/embedded/1.6.4/cdo.html#x1-1250002.3.4
Provider / contact : climaf at meteo dot fr
Input : any object or dataset
Mandatory argument:
latmin
: minimum latitudelatmax
: maximum latitudelonmin
: minimum longitudelonmax
: maximum longitude
Output : the same object, extracted
Climaf call example
>>> ds= .... #some dataset, with whatever variable
>>> sub_ds=llbox(ds, latmin=30, latmax=60, lonmin=-30, lonmax=30)
Side effects : none
Implementation : using cdo with operator sellonlatbox
through script mcdo.sh, which can also select a
variable, a time period …;
Note : it is generally more cost-effective to select the latlon box at the stage of the dataset definition, as in e.g.:
>>> dg=ds(experiment="AMIPV6ALB2G", variable="tas", period="1980-1981", domain=[10,80,-50,40])
