Abstract

Number concentration and size distribution of ambient aerosol particles in air measurements made at 7m above ground level using a 3082 Scanning Mobility Particle Sizer (SMPS) in combination with a 3750 Cloud Particle Condenser (CPC) at the Manchester Air Quality Site (MAQS) for the Integrated Research Observation System for Clean Air (OSCA) project.

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. CPC data were checked using intercomparison with other CPC instruments. 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:
No response or zero factor implimented but intercomparison between CPCs Data obtained and PSI is passed through inlet to check for alignment on various occasions. For intercomparison document, see GitHub folder.
File Format:
NetCDF and CSV format
