Dear ECMWF software support,
I am a graduate student at Penn State University researching hurricane Sandy
track and cyclone phase space forecasts from the ECMWF ensembles and other
forecasts. I need the data in GRIB1 format for use in the GFDL vortex tracker
to generate the phase space forecasts. I downloaded the GRIB2 TIGGE data, but
this data cannot be converted to GRIB1 using the program cnvgrib, even though
all the other TIGGE models successfully convert.
Is there a good method to convert ECMWF TIGGE data from GRIB2 to GRIB1? Is
Grib_API able to do this? It is OK if some of the data is lost; I just need to
have usable GRIB1 data on which to run the vortex tracker.
Thank you very much,
Alex Kowaleski
