Daily albedo product coupling topographic effects retrieved from MODIS data over the Qilian Mountain area(2019)

This dataset is the daily temopral resolution land surface albedo product over Qilian Mountain Area in 2019, with a spatial resolution of 500m. The BRDF / albedo model coupled with topographic effects is used to retrieve the parameters from MODIS land surface reflectance, where the prior knowledge is introduced for quality control. MODIS surface reflectance data is downloaded from the official website, and the daily resolution BRDF is composited with a period of 5 days, and albedo is estimated. The validation results shows it meets the accuracy requirements of albedo application. Compared with similar products, it has more advantages in capturing rapidly changing surface features, and has better temporal and spatial continuity. It can effectively support the study of radiation balance and environmental change in Qilian mountain area.

File naming and required software

File naming convention: MOD0AL.YYYYDDD.hHHvVV.hdf(YYYY: year, DDD: Day (Julian day) HH and VV refer to MODIS standard tile number ), such as MOD0AL.2016001.h24v04.hdf, which represents the albedo of tile h24v04 on the first day of 2016
Data version number: v1
Projection: Standard sinodiol projection is consistent with MODIS products
Data format: HDF 2400 rows * 2400 columns*20波段
Fill value: 32767
Scale: / 10000 (integer value storage, divided by 10000, is the albedo)
