3 Hourly ICON outputs from irrigation long-term simulation

While some regional simulations in Europe have focused on short-term impacts during a single growing season, comprehensive long-term simulations across the entire continent are lacking. Our study aims to quantify the long-term impact of irrigation on surface and atmospheric variables over the EURO-CORDEX domain using convection-permitting ICON simulations that cover a period of 12 years.

The irrigation parameterization is based on the CHANNEL scheme in WRF (Valmassoi et al. 2020). The daily irrigation volume matches the readily available water (RAW), which is the amount of total available water (TAW) a crop can absorb from the root zone without stress. The irrigation event starts on May 1st of each year at 5 UTC for 5 hours, with a frequency of every 12 days.
