[RegCNET] Error reading SST data from ERA Interim

[Béatrice MOREL]

Dear RegCM's users,

I am trying and running RegCM 4.1 with the SST data from ERA-Interim at 1.5° resolution.

I have downloaded data directly from the ERA Interim website. The downloaded file has the following attributes:

ncdump -h sstERAIN.2004_2005.nc 
netcdf sstERAIN.2004_2005 {
dimensions:
	longitude = 240 ;
	latitude = 121 ;
	time = UNLIMITED ; // (2924 currently)
variables:
	float longitude(longitude) ;
		longitude:units = "degrees_east" ;
		longitude:long_name = "longitude" ;
	float latitude(latitude) ;
		latitude:units = "degrees_north" ;
		latitude:long_name = "latitude" ;
	int time(time) ;
		time:units = "hours since 1900-01-01 00:00:0.0" ;
		time:long_name = "time" ;
	short sstk(time, latitude, longitude) ;
		sstk:scale_factor = 0.000600706197210905 ;
		sstk:add_offset = 287.908701051615 ;
		sstk:_FillValue = -32767s ;
		sstk:missing_value = -32767s ;
		sstk:units = "K" ;
		sstk:long_name = "Sea surface temperature" ;

// global attributes:
		:Conventions = "CF-1.0" ;
		:history = "2012-03-26 08:46:58 GMT by mars2netcdf-0.92" ;
}


I have modified the subroutine mod_sst_ersst.f90:

- with regards to the name of the input file which covers the period of interest (2004-2005)
- to change varname from "sst" to "sstk" 

But I am not sure whether the data file has the correct format as I get an error when executing sst:

The error I get looks like:

Cannot get sstk  from file
NetCDF: Not a valid ID                                                         
  
ERROR READ SST

Does anyone have any idea why I get this error?

Many thanks by advance for your response.

Best regards,
