Time period

The recent data will be treated in priority. The period 1997-2000 is the first objective. This period will be then extended to the actual years to treate the new sensors (ENVISAT, AEOS2, AQUA and MSG). The study period will then cover the years before 2009, last year of the AMMA program.

Temporal resolutions

The temporal resolution of each product will be chosen according to the resolution of the sensor used and the considered scale and temporal variability of the geophysical parameter. For exemple, for the large scale products, the temporal resolution can vary from some hours to one month.
