Infrastructure – In-situ Data
Main use of in-situ data is for calibration and
validation of satellite data
Reduce bias of satellite-derived data
Reduce the need for high radiometric calibration
Maximise/enhance the effectiveness of satellite data
Constrain models (data assimilation)
European Environment Agency (EEA) led work for
Copernicus under the FP7 GMES In-Situ
Coordination “GISC” project (finished October 2013)
GMES In-situ Coordination – GSIC
Goals:
To document the in-situ data required by the services
To identify gaps
To design an innovative and sustainable framework for
open access to in-situ data
Monitoring networks currently provide robust
integrated information and calibrate and validate
the data from satellites
