考虑地表二向反射的青藏高原Landsat地表反射率产品
Landsat surface reflectance products based on BRDF correction over Qinghai-Tibetan Plateau
摘要
Abstract
The surface reflectance products based on BRDF correction can decrease the variability of surface reflectance caused by changes in solar incidence angles and satellite viewing angles,so these products perform higher accuracy and radiative consistency by comparing with surface reflectance products that only undergo atmospheric correction.By using 6S-based atmospheric correction method and the C-factor BRDF correction method,the high-quality surface reflectance products over the Qinghai-Tibetan Plateau in 1990,2000,2010,2015,2020,and 2022 are generated.The processing steps to these products include radiometric calibration,atmospheric correction,and BRDF correction.The RMSE is less than 0.035,and R2 is more than 0.9 of the Landsat surface reflectance by validated with the field-measured surface reflectance data.The results are finally saved in GeoTIFF format,accompanied by corresponding quality and metadata files.The product can be applied in fields such as quantitative retrieval of remote sensing surface parameters,agriculture and forestry,and climate change research in Qinghai-Tibetan Plateau.关键词
