CHELSA climatologies at high resolution for the earth's land surface areas (Version 1.1)

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（http://chelsa-climate.org/）是一款针对地球陆地表面的高分辨率（30弧秒，约1公里）气候数据集。该数据集涵盖了1979-2013年期间每月和每年的平均温度与降水模式，以及由此派生的生物气候和年际参数。CHELSA_v1.1基于对ERA interim全球环流模型（http://www.ecmwf.int/en/research/climate-reanalysis/era-interim）进行的一种准机械统计降尺度，并结合了GPCC（https://www.dwd.de/EN/ourservices/gpcc/gpcc.html）和GHCN（https://www.ncdc.noaa.gov/ghcnm/）的偏差校正。
