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.

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 NCAS British Atmospheric Data Centre (NCAS BADC) Data Center Contact +44(0)1235 446432 British Atmospheric Data Centre STFC Rutherford Appleton Laboratory Harwell Oxford OX11 0QX UK badc@rl.ac.uk distributor https://catalogue.ceda.ac.uk/uuid/1f07bbdcd5ced0b485dd4f32298201f1 CEDA Data Catalogue Page Detail and access information for the resource information http://data.ceda.ac.uk/badc/nerc-assim-prog/data/atmoschem DOWNLOAD Download Data download dataset Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08 Data collected and prepared by project participants before submission to BADC for archiving
