The response to temperature of sample hyperspectral radiometers commonly used to support the validationof satellite ocean color data was characterized in the 400–800-nm spectral range. Measurements performed in the10–40C interval at 5C increments showed mean temperature coefficients varying from -0.04x10-2 (C)-1 at400 nm to +0.33x10-2 (C)-1 at 800 nm, which are largely explained by the temperature coefficient of thephotodetector array constituting the core of the sensor. Overall, the results indicate the possibility of applyingtemperature corrections with an uncertainty of approximately 0.03x10-2 (C)-1 for the class of hyperspectralradiometers investigated in the study.JRC.D.2-Water and Marine Resource
