title: Data from: MERRAclim, a high-resolution global dataset of remotely sensed bioclimatic variables for ecological modelling

description: Species Distribution Models (SDMs) combine information on the geographic
 occurrence of species with environmental layers to estimate distributional
 ranges and have been extensively implemented to answer a wide array of
 applied ecological questions. Unfortunately, most global datasets
 available to parameterize SDMs consist of spatially interpolated climate
 surfaces obtained from ground weather station data and have omitted the
 Antarctic continent, a landmass covering c. 20% of the Southern Hemisphere
 and increasingly showing biological effects of global change. Here we
 introduce MERRAclim, a global set of satellite-based bioclimatic variables
 including Antarctica for the first time. MERRAclim consists of three
 datasets of 19 bioclimatic variables that have been built for each of the
 last three decades (1980s, 1990s and 2000s) using hourly data of 2 m
 temperature and specific humidity. We provide MERRAclim at three spatial
 resolutions (10 arc-minutes, 5 arc-minutes and 2.5 arc-minutes). These
 reanalysed data are comparable to widely used datasets based on ground
 station interpolations, but allow extending their geographical reach and
 SDM building in previously uncovered regions of the globe.

 data from MERRA. Temperature layers (BIO1-BIO11) are in degree Celsius
 multiplied by 10, humidity layers (BIO12-BIO19) are in kg of water/kg of
