Dear member of CF community,
I got data from GCM-output to convert to netCDF with CF-standard.
The data include multiple forecasts from multiple analysis (6-hourly
analysis and additional 3h and 6h forecast).
Therefore I introduced an additional forecast dimension, but the
'CF-Convention compliance checker' refused that solution.
How should the structure looks like?
Thanks for your help,
Beate Geyer

dimensions:
time = UNLIMITED ; // (5 currently)
forecast = 3 ;
lat = 1 ;
lon = 1 ;
tbnds = 2 ;
variables:
float ASOD_T(time, forecast, lat, lon) ;
ASOD_T:units = "W m-2" ;
ASOD_T:long_name = "toa downward
shortwave radiation" ;
ASOD_T:standard_name =
"toa_incoming_shortwave_flux" ;
float forecast(forecast) ;
forecast:units = "h" ;
forecast:standard_name =
"forecast_period" ;
float lat(lat) ;
lat:units = "degrees_north" ;
lat:long_name = "latitude" ;
lat:standard_name = "latitude" ;
float lon(lon) ;
lon:units = "degrees_east" ;
lon:long_name = "longitude" ;
lon:standard_name = "longitude" ;
double time(time) ;
time:units = "minutes since 1970-01-01
00:00:00" ;
time:standard_name = "time" ;
time:bounds = "time_bnds" ;
double time_bnds(time, tbnds) ;
time_bnds:units = "minutes since
1970-01-01 00:00:00" ;
time_bnds:long_name = "time bounds" ;
// global attributes:
:Conventions = "CF-1.0" ;
data:
forecast = 0, 3, 6 ;
time = 17223720, 17224080, 17224440, 17224800, 17225160 ;
}
