A pre-operational Data Targeting System (DTS) was developed to assess the feasibility of operational adaptive control of the observing system and as a facility to aid research projects using data targeting. The DTS was developed and hosted at ECMWF. The work was jointly funded by EUCOS and the EC as part of the PREVIEW Integrated Project (work package WP3320) of the EU 6th Framework Programme.

The objective of the EU-funded DEMETER project is to develop a well-validated European coupled multi-model ensemble forecast system for reliable seasonal to inter annual prediction. Six comprehensive European global coupled atmosphere-ocean models are being installed at ECMWF, those of: ECMWF, Météo-France, LODYC, Met Office, MPI, INGV, INM-HIRLAM and CERFACS.

Divergence of horizontal air flow or winds is a measure of the spreading out of air at a particular point. Divergence is +ve where air spreads out; –ve where air converges...
