Abstract

This dataset contains the output of gridded JULES (Joint UK Land Environment Simulator) runs from 1980-2019 over Europe before and after the 4DEnVar data assimilation of satellite ESA CCI (Climate Change Initiative) soil moisture, This output is from work-package WP1.2 of the HORIZON Europe EXPECT project: “Towards an Integrated Capability to Explain and Predict Regional Climate Changes”.

Forcing data from the Watch Forcing Data ERA5 data set was used. The ESA CCI soil moisture data was assimilated using the 4DEnVar technique of Pinnington et al. (2021), which assumes the 15 parameters of the Tóth pedotransfer function (PTF) are constant over the entire region of Europe. The JULES suite u-dx313 was used to determine the posterior PTF parameters for the time period 2014-2018, followed by full JULES runs with suite u-du244 for both the prior and the posterior PTF parameters from 1980-2019.

JULES for HORIZON Europe EXPECT

Abstract

JULES (Joint UK Land Environment Simulator) runs from 1980-2019 over Europe before and after the 4DEnVar data assimilation of satellite ESA CCI (Climate Change Initiative) soil moisture, as WP1.2 of the HORIZON Europe EXPECT project: “Towards an Integrated Capability to Explain and Predict Regional Climate Changes”.
