Characterization and Absolute Calibration of an AERONET-OC Radiometer
The Ocean Color component of the global Aerosol Robotic Network (AERONET-OC) utilizes CE-318 sun photometers modified for above-water radiometry from fixed structures such as oil rigs, lighthouses and service platforms. Primarily, AERONET-OC measurements allow determination of the water-leaving radi...
