收藏资源简介:
Albedo data products are derived from NEON Airborne Observation Platform (AOP) Imaging Spectrometer (NIS) data collected in North-South oriented flight lines to reduce BRDF effects. These data are processed to orthorectified directional surface reflectance and then to Albedo as best practically approximated by wavelength-integrated surface reflectance, weighted with the global flux on the ground. L3 Albedo is distributed in 1 km by 1 km tiles at a 1 m spatial resolution. Instrumentation: NEON Airborne Observation Platform (AOP) Imaging Spectrometer (NIS) - NASA/JPL AVIRIS-NG
反照率(Albedo)数据产品源自美国国家生态观测站网络(NEON)机载观测平台(Airborne Observation Platform, AOP)成像光谱仪(NIS)采集的数据,此类数据采用南北向飞行航线采集以降低双向反射分布函数(Bidirectional Reflectance Distribution Function, BRDF)效应。相关数据首先被处理为经正射校正的定向地表反射率数据,随后进一步处理为反照率,其最优实际近似方式为波长积分地表反射率,并以地面全球通量进行加权计算。L3级反照率数据以1km×1km的瓦片形式分发,空间分辨率为1m。仪器信息:NEON机载观测平台(AOP)成像光谱仪(NIS)——美国国家航空航天局/喷气推进实验室(NASA/JPL)机载可见光/红外成像光谱仪-下一代(AVIRIS-NG)
