CHELSA climatologies at high resolution for the earth's land surface areas (Version 1.1). World Data Center for Climate (WDCC) at DKRZ. https://doi.org/10.1594/WDCC/CHELSA_v1_1
For a detailed description of the methods see: (http://128.84.21.199/abs/1607.00217)
CHELSA_v1.1 is based on a quasi-mechanistical statistical downscaling of the ERA interim global circulation model (http://www.ecmwf.int/en/research/climate-reanalysis/era-interim ) with a GPCC ( https://www.dwd.de/EN/ourservices/gpcc/gpcc.html )and GHCN (https://www.ncdc.noaa.gov/ghcnm/) bias correction.
Resolution: High resolution (30 arcsec, ~1 km), monthly mean coverage 1979 - 2013
Structure: Incorporation of topoclimate (e.g. orographic rainfall wind fields) Downscaled ERA-interim model.
Global grids with the extent: West 180.0001388888 East 179.9998611111 South 90.0001388888 N 83.9998611111, Cell Size 0.0083333333, Number of Columns 43200, Number of Rows 20880. Geographic projection
Boundary condition and input data: Downscaled ERA-interim model and incorporation of topoclimate (e.g. orographic rainfall wind fields)
Avoidance of spatial regression approaches and related problems
Allows calculation of derived parameters based on monthly values such as length of dry periods etc.
