2.1.4. Meteorological Datasets

The reanalysis meteorological datasets from 2003 to 2016 were obtained from the ERA-Interim global reanalysis data (https://apps.ecmwf.int/datasets/data/interim-fulldaily/levtype=sfc/, accessed on 13 December 2020). Here, we selected 2 m temperature, total precipitation and photosynthetically active radiation (PAR) from ERA-5. All of these variables were obtained from the surface-level fields of this reanalysis at 0.125◦ for a daily interval. The potential evapotranspiration (PET) was downloaded from the gridded Climatic Research Unit (CRU) datasets (https://catalogue.ceda.ac.uk/uuid/10d3e3640f004 c578403419aac167d82, accessed on 27 January 2021). The original climate datasets from 2003 to 2016 were aggregated to a monthly time scale at a 0.05◦ spatial resolution to calculate climatic limitation indices.
