This dataset contains: mean growing season (March-September) Potential Evapotranspiration per municipality

COIN2 (COst of INaction 2) aims to quantify the future costs of not mitigating climate change, that would specifically affect Austria. To that end bias-corrected and down-scaled climate projections from the EURO-CORDEX ensemble are used to generate input data for a diverse set of impact models, spanning sectors from forestry and agriculture, health, water supply, tourism, etc.

From the original ÖKS15 (https://doi.org/10.60669/b37q-jd39) datasets:

SDM_ICHEC-EC-EARTH_rcp45_r1i1p1_KNMI-RACMO22E, SDM_ICHEC-EC-EARTH_rcp85_r1i1p1_KNMI-RACMO22E, SDM_IPSL-IPSL-CM5A-MR_rcp85_r1i1p1_IPSL-INERIS-WRF331F and SDM_MOHC-HadGEM2-ES_rcp85_r1i1p1_CLMcom-CCLM4-8-17,

mean daily temperature (tas), minimum (tn) and maximum (tx) daily temperature, mean daily global radiation (rsds) and mean daily 10m wind speed (wind) and from the DISCC-AT (https://doi.org/10.60669/gbdv-gq54) mean daily dewpoint temperature (td) datasets were used to calculate the 20year-mean monthly Potential Evapotranspiration (PET) based on the definition of FAO-56 Penman-Monteith (https://www.fao.org/4/X0490E/x0490e08.htm#penman%20monteith%20equation), averaged over the growing season months March to September for 3 distinct time periods: 2001-2020 (present), 2041-2060 (2050) and 2071-2090 (2080).

The outputs are available on the original ÖKS15 grid as netcdf files, and also averaged to one value per municipality (https://www.data.gv.at/datasets/566c99be-b436-365e-af4f-27be6c536358?locale=de Version: 20250101), as csv-files.
