GF1 WFV Surface Reflectance product
收藏资源简介：
GF1 WFV SR products are generated by the SR retrieval procedure (AirSR) and the GF1 WFV images received by the remote sensing satellite ground station of China. AirSR adopts a per-pixel atmospheric correction method based on the 6S radiative transfer model and MODIS AOD (Aerosol Optical Depth) spatial fusion. The MODIS AOD products used include MOD08D3, MOD09CMA, and MCD19A2, which are spatially fused using the Universal Kriging Method (UK) to obtain a complete coverage of AOD data. The required atmospheric water vapor content and ozone data are from MCD19A2 and MOD09CMG products, which can be downloaded from the MODIS product website (https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/). AirSR also considers the influences of solar zenith angle and satellite observation zenith angle. contacts: zhangzhaoming@aircas.ac.cn/zhangzm@radi.ac.cn
高分一号（GF1）宽幅视野（WFV）超分辨率（SR）产品由空气超分辨率（AirSR）反演流程与中国遥感卫星地面站接收的GF1 WFV遥感影像共同生成。空气超分辨率（AirSR）采用基于6S辐射传输模型与MODIS气溶胶光学厚度（Aerosol Optical Depth, AOD）空间融合的逐像素大气校正方法。所用MODIS AOD产品涵盖MOD08D3、MOD09CMA及MCD19A2，通过泛克里金法（Universal Kriging, UK）实现空间融合，以获取全覆盖的气溶胶光学厚度数据。所需大气水汽含量与臭氧数据取自MCD19A2与MOD09CMG产品，可从MODIS产品官网（https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/）下载获取。空气超分辨率（AirSR）同时兼顾了太阳天顶角与卫星观测天顶角的影响。 联系方式：zhangzhaoming@aircas.ac.cn/zhangzm@radi.ac.cn
