Data from the European Centre for Medium Range Weather Forecasting

These data are global fields of temperature and winds on 31 model levels at T106 resolution. The data are in spectral form and in the grib format. NILU has developed user friendly software to extract and interpolate the data onto a lat. lon. grid at isobaric or isentropic levels. It is also possible to calculate potential vorticity. The T106 data are transferred to NILU through the Norwegian Meteorological Institute on a daily basis.
