Daily minimum teperatures

Daily minimum temperature (sliding average of 3 days) at six altitude levels.

The 2010-2015 results are from the beta-release of the EUMETSAT ROM SAF reprocessed data set,
involving four satellite missions: GRACE, COSMIC, CHAMP and METOP. The average number of daily
profiles in the area north of +50 degrees is 400.
For 2016-2017 the results are based on the operational NRT ROM SAF product from METOP-A and -B. The
typical number of profiles in the area of interest is 160.
