%description
Download climate data for a bounding box, polygon or point and return tidy
tables. Sources are the 'ERA5' reanalysis (Hersbach et al. (2020)
<doi:10.1002/qj.3803>) from the 'Copernicus' Climate Data Store
<https://cds.climate.copernicus.eu/>, India Meteorological Department
(IMD) gridded rainfall and temperature (Pai et al. (2014)
<doi:10.54302/mausam.v65i1.851>), 'HadEX3' climate extremes (Dunn et al.
(2020) <doi:10.1029/2019JD032263>) and 'CRU TS' (Harris et al. (2020)
<doi:10.1038/s41597-020-0453-3>). Computes heat stress indices, including
wet-bulb globe temperature (Liljegren et al. (2008)
<doi:10.1080/15459620802310770>) and the Universal Thermal Climate Index
(Bröde et al. (2012) <doi:10.1007/s00484-011-0454-1>), and heatwave
indicators, including the Excess Heat Factor (Nairn and Fawcett (2015)
<doi:10.3390/ijerph120100227>).
