Experts chart way ahead for satellite cloud and precipitation assimilation

Eighty of the world’s top experts on using satellite cloud and precipitation observations in numerical weather prediction came together at ECMWF from 3 to 6 February to review progress and chart the way ahead.

Some new ocean and sea-ice variables in S2S database

New ocean and sea-ice variables added to 60-day forecast database

Nine new ocean and sea-ice variables have been added to a multi-model sub-seasonal to seasonal (S2S) weather prediction database hosted by ECMWF. The new variables will help researchers to explore the predictability of ocean and sea-ice conditions.
