Abstract

This dataset contains UK Met Office Daily Weather Reports (DWR) from ten sites from the UK Met Office Monthly Weather Records (1884-1993), using the recently-scanned UK Met Office Monthly Weather Reports (MWR). The data are presented as is, with no attempt to provide any corrections or calibration. Approximately half the stations exhibit sharp drops in thunderdays at various points between 1960 and 1990. Comparison with nearby Met Office Integrated Data Archive System (MIDAS) stations suggests the low thunderdays are the result of changes in observing practice, rather than genuine changes in thunderstorm occurrence. These potential data issues limit interpretation of the long-term trends.

DWR contain extensive logs of UK thunderstorm activity, in the form of thunderday observations. To date, only a very small fraction of these data have been digitised as part of the MIDAS dataset, and exclusively after 1950.

Previously used record identifiers:
No related previous identifiers.
Access rules:
Access to these data is available to any registered CEDA user. Please Login or Register for an account to gain access.
Use of these data is covered by the following licence: 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 originates from the Met Office it has been digitised by the data provider without further QC by the Met Office and therefore the Met Office is currently unable to confirm the accuracy of the keying. They have been digitised and deposited at the Centre for Environmental Data Analysis (CEDA) for archiving.

Data Quality:
The data was originally published by the Met Office shortly after its collection and was not subject to further Quality Control checks following publication. As a result it is possible that values from the Met Office MIDAS data base may differ from those held in the DWR and the MWR, and hence the data set available from the CEDA archive.
File Format:
Data are netCDF formatted
