ACSIS: UKESM1 simulations for the North Atlantic Climate System Integrated Study
Abstract
Three UK Earth Sysyem Model (UKESM1) hindcasts have been performed in support of the North Atlantic Climate System Integrated Study (ACSIS).
Data is provided as raw model output in Met Office PP (32-bit) format that can be read by the Iris (https://scitools-iris.readthedocs.io/en/stable/) or cf-python (https://ncas-cms.github.io/cf-python/) libraries.
This is global data at N96eL85 resolution (1.875 x 1.25, 85 model levels up to 85km). Simulations were performed on the Monsoon2 High Performance Computer (HPC).
The following fields are contained in the dataset: O3, NO, NO2, CO, CH4, 4x Stratospheric O3 tracers, and 30x idealised tracers emitted from various locations (15 with a 5-day e-folding lifetime, and 15 with a 30-day e-folding lifetime). Data is provided in mass mixing ratio (kg species/kg air).

Use of these data is covered by the following licence(s): http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/ When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record. |
| Data lineage: |
Data were produced by the project team using the UKESM1-StratTrop model deployed at NCAS-CAMBRIDGE and the output archived at CEDA |
| Data Quality: |
These simulations have been developed over a number of years and had code reviews performed to ensure the coding standard used. All code developments have since been committed to the UM and UKCA trunks for use by the community.

Process overview
| Title | UKESM1-StratTrop model deployed at NCAS-CAMBRIDGE |
| Abstract | One simulation is a UKESM1.0 configuration at UM version 11.5 with additional diagnostics added and "nudged" to ERA-Interim reanalyses for 1981-2014 (u-bv711 and u-bw316) and continued using SSP3-7.0 forcings to 2019 (u-by117). One simulation is a UKESM1.0 configuration at UM version 11.5 with additional diagnostics added and "nudged" to ERA-5 reanalyses for 1982-2014 (u-bw784) and continued using SSP3-7.0 forcings to 2020 (u-by803). The bugfix documented in Ranjithkumar et al. 2021 has been applied (DOI:10.5194/acp-21-4979-2021). One simulation is a UKESM-StratTrop configuration with stratospheric ozone improvements at UM version 11.5 with additional diagnostics and "nudged" to ERA-5 reanalyses for 1982-2014 (u-bv828 and u-bx320) and continued using SSP3-7.0 forcings to 2020 (u-by808). The bugfix documented in Ranjithkumar et al. 2021 has been applied (DOI:10.5194/acp-21-4979-2021). |
