  <dc:description>Abstract: Original forest cover fraction, vegetation cover fraction and fraction of non-vegetated area on 250m grid resolution sinusoidal grid were obtained in HDF file format from https://lpdaac.usgs.gov/mod44bv061/, read together with the bit-encoded quality information and converted into netCDF file format with latitude/longitude coordinates of every 250m x 250m pixel, and decoded quality flag information included (see https://www.cen.uni-hamburg.de/en/icdc/data/land/modis-vcf-forest.html).

TableOfContents: forest cover fraction; other vegetation cover fraction; non-vegetated land cover fraction; forest cover fraction standard deviation; quality flag
