Data and services from NADIR

Do you want access to NADIR?

You need to sign the THESEO 2000 data protocol and the ECMWF data protocol in order to get access to all the data available in NADIR. You can get hold of these protocols by contacting the NADIR team at NILU by e-mail at nadirteam@nilu.no

Meteorological data

NADIR provides meteorological forecasts and analyses from ECMWF. These data are available:

12 UT analyses and 1,2,3,4,5 and 8 days forecasts of T, PV and P at eight isentropic levels from 350K to 950 K. These data are calculated by Bjørn Knudsen at DMI.

12, 36 and 60 hours forecasts of the above mentioned parameters based on the midnight analysis. These forecasts are 12 hours more recent than the ones above, and should therefore be used for short term planning.

Analyses and 1,2,3,4 and 5 days forecasts of T, GPH, u and v at 13 isobaric levels from 1000 to 10 hPa. These data are provided through DNMI.

All the above mentioned data cover the region from 30N to the North Pole and the horizontal resolution is 2.5 by 2.5 degrees.

6-hourly global T₁₀₆ analyses at 60 model levels from the surface to 0.1 hPa. These parameters are available: T, GPH, u, v and PV. Data can be interpolated to isobaric and isentropic levels. The horisontal resolution of extracted data is 1.125 by 1.125 degrees. These data are provided through DNMI.

10-day backward trajectories ending at a large number of sites and grid points. Provided by Bjørn Knudsen, DMI.

PV etc. at stations. Threse data give PV and some other parameters above a selected set of measurement sites. Provided by Bjørn Knudsen, DMI.

More info is to be found on the NADIR web page.

Meteorological maps

Maps of the most important meteorological parameters are available at the NADIR data base. These maps are updated daily.

More info can be found on the NADIR web page.

Experimental data

Experimental data from the European THESEO 2000 and American SOLVE activities are stored in the NADIR database. Mirror routines on zardoz and the NASA homologue makes sure that the two databases are up to date with all experimental data. More information is to be found on the NADIR homepage.
