Abstract: This exploratory analysis is focused on mainland Portugal and aims to compare the intensity-duration-frequency (IDF) curves built upon ERA5-Land reanalysis data and the ones established based on ground observations. The results achieved so far clearly indicate that there is still a long way to go before concluding about the feasibility of using reanalysis data to characterize the intensive rainfall in Portugal.
