Abstract: The response to temperature of sample hyperspectral radiometers commonly used to support the validation of satellite ocean color data was characterized in the 400–800-nm spectral range. Measurements performed in the 10–40C interval at 5C increments showed mean temperature coefficients varying from -0.04x10-2 (C)-1 at 400 nm to +0.33x10-2 (C)-1 at 800 nm, which are largely explained by the temperature coefficient of the photodetector array constituting the core of the sensor. Overall, the results indicate the possibility of applying temperature corrections with an uncertainty of approximately 0.03x10-2 (C)-1 for the class of hyperspectral radiometers investigated in the study.
