Abstract

Two UK Earth System Model (UKESM1) hindcasts have been performed in support of the Virtual Integration of Satellite and In-situ Observation Networks (VISION) project (NE/Z503393/1).

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 N96 L85 resolution (1.875 x 1.25, 85 model levels up to 85km). Simulations were performed on the Monsoon2 High Performance Computer (HPC).

The first dataset (Jan 1982 to May 2022) contains hourly ozone concentrations on the lowest model level (20m above the surface).

The second dataset (Jan 2010 to Dec 2020) contains hourly ozone concentrations and hourly Heaviside function on 37 fixed pressure levels. Data is only provided for days in which ozone was measured by the FAAM aircraft (for comparison purposes).

Ozone data is provided in mass mixing ratio (kg species/kg air).

Data lineage:

Data were produced using a dynamically-constrained version of 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.
