A workshop by ESA at ESRIN, Frascati, Italy will be held from February 27th to March 1st aiming at discussing Land Product Validation:
Retrieving land parameters globally from space has a significant heritage, currently based on satellite missions across the visible and infrared spectral domain, including ERS, Envisat, SPOT-VGT, Landsat and Proba-V. The list of available sensors has recently been extended by the onset of the Copernicus Sentinel-2 and Sentinel-3 missions. In future, missions such as FLEX and BIOMASS, introducing also different observation techniques such as SAR, will complement the list of sensors contributing to the retrieval of land parameters.
Land parameters address surface characteristics across a wide spectrum, including information about vegetation, albedo, temperature, fires, inland waters and snow. To compare observations across different sensors common approaches and protocols for calibration and validation need to be defined, including standards for Fiducial Reference Measurements. With the long-term availability of some of these measurements also the option for climate relevant data series emerges and calls for data harmonisation across sensors.
