Methodology for Computation of UK Windstorm Gust Return Levels on a High Spatial Resolution (100 m) Grid

This document outlines the methodology employed by the Climate Extremes Group in the Department of Space and Climate Physics at University College London (UCL) to compute windstorm gust return levels (from 1 year to 1000 years) at high spatial resolution (100 m grid) for the whole UK. The methodology is summarised under eight headings. A ninth section addresses the precision of the gust return levels. A product format section, references and an appendix provide additional information.
