Abstract
This dataset contains model output data on sulphate aerosols, aerosol size distributions and radiative fluxes produced from experiments that used different values of cloud-water pH. The composition-climate model HadGEM3-UKCA was run over the period 1970 to 2009 to investigate the effect of temporal changes in cloud-water pH on sulphate aerosol formation and the subsequent impact on climate. HadGEM3-UKCA is the climate model configuration of the Met Office Unified Model (UM). Vn7.3 of the UM was used in this study and included a branch to the CLOMAP-Mode aerosol scheme. Model simulations were conducted at a global resolution of 1.875° x 1.25°.

Public data: access to these data is available to both registered and non-registered users.
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 generated using the Met Office Unified Model (UM) Vn7.3 and used in a climate model configuration termed HadGEM3-UKCA that has interactive aerosols (GLOMAP-Mode) and chemistry at a global 140km horizontal resolution (N96, 1.875 x 1.25). Selected model output variables have been processed and converted to CF-netCDF by the author using the IRIS tool developed by the Met Office and then passed on to the Centre for Environmental Data Analysis (CEDA) for archiving. |
