The RadCalNet portal is available at www.radcalnet.org. The portal and its services are currently being beta tested and are not yet open to the public. The portal should however be accessible to the public by summer 2017.
The RadCalNet portal was developed in the frame of the ACTION project, an ESA initiative led by NPL, aiming at supporting the emergence of an operational network of automated instruments for the radiometric calibration of high spatial resolution optical sensors. The outputs of this project are available here
