The new CEOS Cal/Val Portal

The CEOS Cal/Val Portal provides support to worldwide activities on calibration and validation, and specifically ensures that sensor intercalibration is favoured in a standardised way. The overall goal is to increase measurement accuracy of all the sensors which will be supported by this system and to increase the inter-operability between EO platforms
