Return a list containing information of a regular grid / domain

gridInfo(file = file.choose(), z = F, geo = F, verbose = T)

Arguments

file

file name/path to a wrfinput, wrfchemi or geog_em file

z

TRUE for read wrfinput vertical coordinades

geo

True for use geog_em files

verbose

display additional information

Note

just WRF-Chem is suported by now
