Abstract

This dataset contains netcdf files produced from the output of UK Met Office Unified Model atmosphere-only simulations over West Africa for current vegetation and 1950s vegetation scenarios. The region covered is 20W to 20E, 0N-25N and simulations were run for 5 days from 1st June 2014 conditions using boundary conditions and sea surface temperature from ERA-Interim reanalysis.

The files contain ensemble means (from 10 member ensembles) and the results of a paired Student's T-Test between the two scenarios. There are also files for specific longitude bands and some averaged over 16W-16E, 4N-15N for all land, deforested land and unchanged land. The data is mostly hourly and allows analysis of the impact of recent deforestation in this region. The simulations were run by Julia Crook (University of Leeds) on the ARCHER supercomputer.

This data was collected as part of the NERC project 'Vegetation Effects on Rainfall in West Africa (VERA)'.
