Hello ECMWF community,
I am trying download the diabatic heating by radiation, shortwave and longwave radiative heating rate variables from Complete ERA5 global atmospheric reanalysis, using the next script.
#!/usr/bin/env python
import cdsapi
c = cdsapi.Client()
c.retrieve(‘reanalysis-era5-complete’, { # Requests follow MARS syntax
# Keywords ‘expver’ and ‘class’ can be dropped. They are obsolete
# since their values are imposed by ‘reanalysis-era5-complete’
‘date’ : “2020-02-01/to/2020-02-14”, # The hyphens can be omitted
‘levelist’: ‘137’, # 1 is top level, 137 the lowest model level in ERA5. Use ‘/’ to separate values.
‘levtype’ : ‘ml’,
‘param’ : [‘130214’, ‘201013’, ‘201014’], # Full information at https://apps.ecmwf.int/codes/grib/param-db/
# The native representation for temperature is spherical harmonics
‘stream’ : ‘oper’, # Denotes ERA5. Ensemble members are selected by ‘enda’
‘time’ : ‘00/to/23/by/3’, # You can drop :00:00 and use MARS short-hand notation, instead of ‘00/06/12/18’
‘type’ : ‘fc’,
‘area’ : ‘-55/-75/-68/-45’, # North, West, South, East. Default: global
‘grid’ : ‘1.0/1.0’, # Latitude/longitude. Default: spherical harmonics or reduced Gaussian grid
‘format’ : ‘netcdf’, # Output needs to be regular lat-lon, so only works in combination with ‘grid’!
}, ‘ERA5_diab.nc’) # Output file. Adapt as you wish.
However, the script generated an error and MARS returned no data. Are these variables available for download? Could anyone help me resolve this error, please?
Cheers,
Christian
