Field Radiometric Calibration of a Micro-Spectrometer Based on Remote Sensing of Plateau Inland Water Colors

Remote sensing reflectance (Rrs), which is currently measured mainly using the above-water approach, most crucial parameter in remote inversion of plateau inland water colors. It very difficult to measure Rrs unmanned areas; thus, we provide a measurement solution micro-spectrometer. Currently, commercial micro-spectrometers are not factory calibrated for radiation, and radiometric calibration micro-spectrometer an essential step. This article uses Ocean Optics (STS-VIS) traditional spectrometer (Trios) simultaneously irradiance radiance diffuse plates with different values field calibration. The results show following: (1) fiber types have coefficients, integration time determined according diameter type fiber, (2) by comparing simultaneous STS-VIS Trios, mean absolute percentage difference (MAPD) both reached 18.64% 5.11% Qinghai Lake Golmud River, respectively, accurate measurements bodies. Hoh Xil Qarhan Salt bodies areas China was measured, this first collection situ spectral information shows that can perform areas. With breakthrough performance micro-spectrometer, able obtain more
