Data from Cambridge Chemical data assimilation model at Cambridge University computer for the Assimilation of Remote-sensed Data for Applications in the Atmospheric and Oceanographic Sciences (ARDAAOS) NERC Research Programme Project

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.

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
