Abstract

This dataset contains global model data generated for volcanic halogen simulations. Model used was the United Kingdom Earth System Model 1.0 (UKESM1.0), in an atmosphere-only configuration, with Met Office Unified Model version 11.2. The data is on a global N96 grid (192 x 144 points), and is a mid 1990s timeslice. These data were used to study the impact of co-emission of volcanic halogens on atmospheric composition and radiative forcing.

There are 6 experimental integrations for sulfur only (u-bw537, u-bw539, u-bw541, u-bs104, u-bs110, u-bs112) and sulfur & halogens (u-bw538, u-bw540, u-bw542, u-bs109, u-bs111, u-bs113), and a control (u-bs034) for each year. The files are labeled using variable codes such as m01s34i001 to determine the model variable field contained. A full description of what these are can be found in the included file variable_codes.txt.

The datasets are in NetCDF format, and were generated from the above model suites.

Title

UK Chemistry Aerosol Community Model - UKCA deployed on Cambridge University computer
Abstract

This computation involved: UK Chemistry Aerosol Community Model - UKCA deployed on Cambridge University computer. UKCA is a joint NCAS-Met Office programme funded by NCAS, GMR and DEFRA. Project partners are the Hadley Centre and the Universities of Cambridge and Leeds. Our objective is to develop, evaluate and make available a new UK community atmospheric chemistry-aerosol global model suitable for a range of topics in climate and environmental change research.
