Data to support "Reduced winter-time Clear Air Turbulence in the trans-Atlantic region under Stratospheric Aerosol Injection by Katie L Barnes, Anthony C Jones, Paul D Williams and James M Haywood, Submitted to Geophysical Research Letters, November 2024"

<p>This dataset contains all the UKESM1 climate model output needed to reproduce Figures 1-4 in the paper "Reduced winter-time Clear Air Turbulence in the trans-Atlantic region under Stratospheric Aerosol Injection by Katie L Barnes, Anthony C Jones, Paul D Williams and James M Haywood, Submitted to Geophysical Research Letters, November 2024". UKESM1 is the Met Office Earth System Model (N96 resolution) with simulations using a fully-coupled ocean-atmosphere following CMIP6 protocol.</p> <p>All files are CF-1.7 compliant and in NetCDF format with appropriate metadata. Each file contains 6 hourly data for the 30 simulated years used in the paper (50 for the pre-industrial control period).</p> <p>The following simulations are included, following ScenarioMIP and GeoMIP specifications:</p> <p>Folder | Simulation name | Time period<br>-------------------------------------------------------------<br>piControl | PiControl | 2250-2299<br>historical | Historical | 1985-2014<br>ssp245 | SSP2-4.5 | 2070-2099<br>ssp585 | SSP5-8.5 | 2070-2099<br>g6sulfur | G6sulfur | 2070-2099</p> <p>The files use CMIP-like naming conventions.</p> <p>VARIABLE_LEVEL_TIMEPERIOD_MODEL_EXPERIMENT_STARTDATE-ENDDATE_SEASON.nc</p> <p>The variables comprise:</p> <p>Short name | Description (units, if any)<br>-------------------------------------------------------------<br>ua | zonal wind (m.s-1)<br>va | meridional wind (kg.m-3)<br>ta | air temperature (K)</p> <p>All figures in the paper were produced using Python (3.11) and Iris scientific analysis software.</p> <p>All data is Crown Copyright, Met Office, and is made available under the terms of the Non-Commercial Government Licence: http://www.nationalarchives.gov.uk/doc/non-commercial-government-licence/version/2/</p> <p>Description of the UKESM1 model is provided in Sellar, A.
