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.","keywords":"ATMOSPHERICWINDS ATMOSPHERE ALTITUDE AEROSOLS ATMOSPHERICTEMPERATURE ATMOSPHERICCHEMISTRY ATMOSPHERICPRESSURE","publicationState":"published","dataPublishedTime":"2007-02-26T23:38:53","doiPublishedTime":null,"updateFrequency":"notPlanned","status":"completed","result_field":{"ob_id":"https://catalogue.ceda.ac.uk/api/v2/observations/6582/?format=json","dataPath":"/badc/nerc-assim-prog/data/atmoschem","oldDataPath":[],"storageLocation":"internal","storageStatus":"online","volume":75117961454,"numberOfFiles":100866,"fileFormat":"<div property=\"cedacat:formats\">\n<div class=\"formats\">Data availability and file format</div>\n\n<p>The file format is a column-based plain text file with one file for each day of observations from each instrument.
