Dear all,

 I had downloaded a netcdf ERA5 reanalysis data from the ECMWF.

I made some attempt to open/read such this file inside IDL V6.2 under windows system.

Unfortunately, I failed.

I will be appreciate  any one help me and have some tips to open/read such this data inside IDL V6.2 in

windows system.

Best Regards

Khaled

Dear Kevin,

here is the code I wrote..

=========

pro Open_read_ERA5_nc

filename='C:\Users\Khaled Tahoon\Desktop\NC\Era5_Reanalysis_hourly_19-7-2012.nc'
failname = NCDF_EXISTS()
help,filename, /structure
; Open the netCDF file:
id = NCDF_OPEN('filename')
; Get the variable ID for variable "Era5_Reanalysis_hourly_19-7-2012":
varid = NCDF_VARID(filename, 'Era5_Reanalysis_hourly_19-7-2012')
d_lev= ncdf_varid(varid,"lev")
print, d_lev
print, n_elements(filename.lev), n_elements(filename.lat), n_elements(filename.lon), n_elements(filename.time)
print, filename.level
print, filename.data
print, filename.lon
print, filename.lat
NCDF_CLOSE, filename

end

===========

this is the following error

Compiled module: OPEN_READ_ERA5_NC
IDL> .CONTINUE
NCDF_VARID: 1 is not a valid cdfid.
