Abstract

The Cambridge Chemical Assimilation Data was produced as part of the Assimilation of Remote-sensed Data for Applications in the Atmospheric and Oceanographic Sciences (ARDAAOS) Natural Environment Research Council (NERC) thematic programme. It presents Chemical assimilation data from multiple sources, which is processed into a common file format making it easy to compare data from the various field campaigns and satellite missions.

Access rules:
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: 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 collected and prepared by project participants before submission to BADC for archiving

Data Quality:
Experimental data collated by project participants as part of a data assimilation project
File Format:
Data availability and file format

The file format is a column-based plain text file with one file for each day of observations from each instrument. The data usually consist of the date, time and location of the measurement along with the measurement itself and an estimate of the error on that value. In addition to these we add several other quantities describing the atmosphere at that location and time. The full list is given in the table below. Those quantities marked with an asterisk (*) are used as co-ordinates and may be used to specify limits in the search process.

 Day  Month  Year*  Day of year*
 Time (GMT)  Longitude*  Latitude*  Temperature
 Pressure*  Geopotential height*  Potential temperature*  Potential vorticity
 Equivalent latitude*  Equivalent length  Data  Error
