Zhang, Y; Zheng, ZJ; Hu, XQ; Rong, ZG; Zhang, LJ (2013). Lake Qinghai: Chinese site for radiometric calibration of satellite infrared remote sensors. REMOTE SENSING LETTERS, 4(4), 315-324.

Abstract
Lake Qinghai is the most important of the Chinese radiometric calibration sites (CRCSs) for on-orbit radiometric calibration of satellite infrared (IR) channels. This letter introduces the site and describes annual CRCS field experiments, the buoy measurement facilities and surface temperature spatial distribution analysis based on Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra (EOS AM) satellite and buoy data for Lake Qinghai. The lake located at a high altitude (3196 m) has clean water, a stable geological substrate and a dry and clear atmosphere, with few aerosol particulates. The spatial distribution of the water surface temperature is very uniform. For these reasons, Lake Qinghai is a good thermal IR target for the radiometric calibration of Earth observation remote sensors and is used not only for Chinese satellites but also for on-orbit radiometric calibration of many Earth observation satellites.
