- 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 (http://apps.ecmwf.int/datasets/data/tigge_lam/licence/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.
