Previous Info:
No news update for this record
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 are collected by the project team and transfered directly from the instrument to the computer database, before being transferred to the general database, where it is processed, averaged over minute time intervals and flagged where data is suspect. Once complete, data are uploaded to CEDA for archiving.
Data processing software found in: https://github.com/ncasuk/AMF_CVs/releases/tag/v1.0.0
Data Quality:
This data is then audited using a baseline zero level and the response factor every 6 month audit. If the zero-corrected O3 level falls below 0 or above 300 ppb it is flagged.
File Format:
NetCDF and CSV format
