standard_name = 'lwe_thickness_of_precipitation_amount'

long_name = 'Total precipitation amount'

units = 'mm'

description = 'Total rainfall'

label_units = 'mm'

plot_label = 'Total rainfall (mm)'

cell_methods = 'time: sum'

coordinates = 'geo_region'

region

Size: 23x1

Dimensions: region

Datatype: int32

Attributes:

units = '1'

standard_name = 'region'

geo_region

You can load/ read the data from netCDf file using ncread.

data = ncread("myncFile",'rainfall') ;
