Evaluación del modelo de superficie terrestre Noah-MP para la selección de esquemas de parametrización en la península ibérica

Abstract

This study evaluates the effectiveness of the Noah-MP Land Surface Model integrated into the WRF v3.9.1 framework for high-resolution climate modeling across the Iberian Peninsula (IP), focusing on its parameter sensitivity for accurately depicting the region's varied climate conditions. The study uses the ERA5 reanalysis data to drive WRF simulations at two resolutions: a broader 50 km domain aligning with the Euro-CORDEX area and a more detailed 10 km domain concentrated on the IP. The methodology incorporates a preliminary spin-up phase consisting of 30-year simulations to ensure soil variable stability, followed by a series of 52 one-year experiments over 26 different parameter settings aimed to improve the model's precision for both wet and dry years. Critical parameters, including vegetation dynamics and soil heat transfer processes, are adjusted to determine their optimal configurations. This approach seeks to improve the model's capability in capturing the climate dynamics and land-atmosphere interactions processes in the IP.
