A 2001–2015 Archive of Fractional Cover of Photosynthetic and Non-Photosynthetic Vegetation for Beijing and Tianjin Sandstorm Source Region

The data cover land ranging from 38°50′ to 46°40′ N and from 109°30′ to 120°30′ E. The archive starts in January 2001 and ends in December 2015. It contains one raster layer per month for each of these variables:

Fractional cover of PV (%)

Fractional cover of NPV (%)

Fractional cover of bare soil (%)

The archive is managed in a Geographic Information System (GIS). All the layers are in the GeoTiff format. The valid data range spans from 0 to 100.The no data pixels are illustrated by 255.

The archive is organized in three large compressed files,one per variable. File names are according to the following conventions:

Characters 1–5: region name (btssr)

Characters 6–7: variable name (pv, np, or bs)

Characters 8–11: year (2001 to 2015)

Characters 12–13: month (01 to 12)

For example, ‘btssrnp200508’ refers to the fractional cover of NPV in August 2005 for the BTSSR.
