In this study, we evaluated the meteorological input for RET from reanalysis data.
Our assessment entails three components: uncertainty between products, nominal accuracy, and quantitative impact of uncertainty in inputs on RET.
The uncertainty between products was assessed by spatial and temporal pair-wise comparison. The nominal accuracy was assessed by comparison with time-series data from in-situ measurements. Finally, the impact of uncertainty in inputs on RET was assessed by two error propagation methods (Monte Carlo simulations and Taylor expansion)
