ObjectivesObjectivesThe general goal of the project is to:The general goal of the project is to:

1.1. investigate/develop quantitative methods for investigate/develop quantitative methods for the optimal design of observing systems for the optimal design of observing systems for nowcasts/forecasts in coastal/shelf seas, nowcasts/forecasts in coastal/shelf seas,

2.2. demonstrate these techniques on SST and T/S demonstrate these techniques on SST and T/S profile observing networks in the Baltic and profile observing networks in the Baltic and North SeaNorth Sea

in the Baltic and North Sea is in general in the Baltic and North Sea is in general sufficient for generating daily gridded SST sufficient for generating daily gridded SST maps in 10km resolution, provided all the maps in 10km resolution, provided all the data resources can be fully exploited. This data resources can be fully exploited. This includes AATSR, 3 NOAA-AVHRR, GTS, includes AATSR, 3 NOAA-AVHRR, GTS, monitoring cruises, buoys, Ferry boxes and monitoring cruises, buoys, Ferry boxes and national coastal stations. national coastal stations.

More observations should be made More observations should be made available in the eastern Baltic and coastal available in the eastern Baltic and coastal upwelling area, e.g., ferrybox lines from upwelling area, e.g., ferrybox lines from Riga – Helsinki and from Klaipeda – Riga – Helsinki and from Klaipeda – Sassnitz.Sassnitz.
