Arctic ROOS http://arctic-roos.org In situ observation systems: ship-borne systems, moorings, ice buoys, floats and drifters (DAMOCLES, etc.) Satellite remote sensing: polar orbiting satellites using active and passive microwave, optical and infrared instruments Modelling: data assimilation, nowcasting, short term forecasting, seasonal forecasting, climate modelling, model comparison and validation (MERSEA and MyOcean)

Satellite observations of sea ice Well-established for large-scale monitoring of ice area and extent Source: http://arctic-roos.org

MONARCH-A FP7 Space The aim is to generate a dedicated information package tailored to a subset of multidisciplinary Essential Climate Variables and their mutual forcing and feedback mechanisms associated with changes in terrestrial carbon and water fluxes, sea level and ocean circulation and the marine carbon cycle in the high latitude and Arctic regions.
