Name
Climatologies at high resolution for the earth's land surface areas (Version 1.1)
Acronym
CHELSA_v1_1
Project(s)
CHELSA (Climatologies at high resolution for the earth's land surface areas)
Summary
CHELSA_v1.1 (http://chelsa-climate.org/) is a high resolution (30 arc sec, ~1 km) climate data set for the earth land surface areas. It includes monthly and annual mean temperature and precipitation patterns as well as derived bioclimatic and interannual parameters for the time period 1979-2013. 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.

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.
