Remote-sensing reflectance determined from spectral data set within intercalibration campaign from Lake Süßer See (Germany) during the Inland Water Remote Sensing Validation Campaign 2017

Radiometric measurement with Trios Ramses system. All Trios measurements averaged over reliable common times. The viewing zenith angle was approx. 45°. The surface reflectance factors rho are only given for 40 or 50°. If rho is to high, there is an overcorrection of Lw and Rrs. For this three methods for correction are applied: constant factor rho, Mobley 1999 and Mobley 2015 (Mobley 1999 related to 50°, Mobley 2015 related to 40°).

Spectral particulate absorption and attenuation coefficients derived from unterwater measurements from Lake Geiseltal (Germany) during the Inland Water Remote Sensing Validation Campaign 2017

Measurements were taken from Wetlabs AC-S a spectral absoption and attenuation sensor and Wetlabs FL3W an underwater fluorometer with three channels(chlorophyll, pycoerythrin, CDOM flurorescence). Data is quality assured. The measured parameters from AC-S are attenuation and absorption coefficients (latter with scattering error). Results of attenuation channel used, results of absorption channel not used. Data are corrected for temperature and salinity, blank measurements of HE488 was used for blanking, remaining temperature effects are removed manual, choosen a correct temperature differences. Detector angle error of attenuation channel not corrected. All results are averages of measurements over 10-20 min. Total scattering coefficients provided, from AC-S attenuation minus PSICAM absorption results. The measured parameters from FL3W are using calibration of manufacturer. All results are averages of measurements over 10-20 min. For both sensors no standard deviations provided, but data are available.
