MODIS Terra surface reflectance products over the Tibetan Plateau (2000-2019)
1)File name rules:the data of land surface reflectance is stored in units of years in a floder named surface_reflectance, and the subfolder's name is presented as "date",for example, 2000; the name rule of each file of land surface reflectance result is "MOD09A1_date_sur_refl_bxx.tif",for example, MOD09A1_2001017_sur_refl_b02.tif; the name rule of quality indentification data is "MOD09A1_date_sur_refl_qc_500m.tif" and "MOD09A1_date_sur_refl_state_500m.tif"; the name rule of angle data is "MOD09A1_date_sur_refl_szen.tif", "MOD09A1_date_sur_refl_szen.tif" and "MOD09A1_date_sur_refl_raz.tif", which represent the file of solar zenith angle, view zenith angle and relative azimuth angle; and the name rule of date description is "MOD09A1_date_sur_refl_day_of_year.tif". 2)How to use the dataset: the dataset can be opened by ArcGIS, envi, QGIS and so on, the surface reflectance data are multiplied 0.0001 when used, and the background filling value is -28672; the background filling value of band specific quality data (sur_refl_qc_500m) is 4294967295; the background filling value of surface reflectance state(sur_refl_state_500m) is 65535; and the angle data are multiplied 0.01, and the background filling value is 0.
Using this data, the data citation is required to be referenced and the related literatures are suggested to be cited.
