Hi Kevin:
there are two issues going on:
1) we get constant, intermittent HTTP failures from
nomads.ncep.noaa.gov domain, in both the browser and TDS. I suspect
their servers are overwhelmed. Just retry.
2) that dataset has an ensemble dimension that IDV/CDM doesnt
recognize. the main problem is that the CDM doesnt currently parse the
"GRaDS" conventions, which doesnt seem to be published. theres probably
an NcML workaround in case that helps.

Hi all,
Any idea why IDV does not recognize GFS Ensemble files from
nomads.ncep.noaa.gov:9090/dods/gens as grid files?
For any of the catalog items listed when I browse this directory, I
get an error of the form (e.g. perturbation run # 20 from 12Z run today):
There was an error loading the data:
Error creating data source:dods.grid with:
http://nomads.ncep.noaa.gov:9090/dods/gens/gens20110406/gep20_12z
Grid data source failed making data set:
dods://nomads.ncep.noaa.gov:9090/dods/gens/gens20110406/gep20_12z
/gens/gens20110406/gep20_12z is not an available dataset
The specific exception is:
opendap.dap.DAP2Exception: /gens/gens20110406/gep_all_12z is not an
available dataset
Other models (e.g. GFS) load fine from this NOMADS server.
Thanks,
Kevin
