• How do I get the TIGGE data?
  You can download the TIGGE data via one of the data portals hosted by either ECMWF or CMA, after a simple registration procedure. For further details, see the data access section of the tools page.
• Why can't I download the most recent data?
  Because of the data policy restricting the access to the TIGGE data with a delay of 48 hours after initial time of the forecasts (TIGGE data usage licence)
  
  
• How can I use TIGGE  if I can't read GRIB2 format data?
  Several tools are available to convert GRIB2 data to NETCDF, and also to use the data in either the original GRIB2 format or NETCDF - for more information, please see the links on the tools page.
