Evaluation of snow extent time series in the Himalaya-Hindukush (1982-2018)- A Big Earth Data Platform for Three Poles

This dataset is derived from the paper: Xiaodan Wu, Kathrin Naegeli, Valentina Premier, Carlo Marin, Dujuan Ma, Jingping Wang, Stefan Wunderle. (2021). Evaluation of snow extent time series derived from AVHRR GAC data (1982-2018) in the Himalaya-Hindukush. The Cryosphere, 15,4261-4279.

ln this paper, the performance of the AVHRR GAC snowpack product in the Hindu Kush Himalayas is comprehensively evaluated for the first time on a long time scale (1982-2018) based on ground station data, Landsat data, and MODIS snowpack product, respectively, including the consistency of the accuracy/precision of the product over a long time series, and the consistency of the product with Landsat and MODIS snowpack data in terms of spatial distribution. The main factors affecting the accuracy of the AVHRR GAC snowpack product are also revealed.

File naming and required software

The dataset consists of data tables with the following names and contents data list: a list of data.
t1: Daily global Snow Cover Fraction - snow on ground (SCFG) from AVHRR (1982 - 2019) over Hindu Kush Himalayas (daily snow cover data for the Hindu Kush-Himalayan region over a long period of time (1982-2019)).
t2: Landsat TM/ETM snow data over the areas corresponding to two tiles of Landsat data (path 140, rows 40 and 41, denoted as "P140-R40/41 ") (Landsat snow data set for the "P140-R40/41" area).
t3: The topographical variability within a certain AVHRR GAC pixel over Hindu Kush Himalayas (topographical variability factor within 5 km scale image elements), which was calculated based on SRTM data.
