Infrared radiances from the Limb Infrared Monitor of the Stratosphere (LIMS) instrument, mounted on the Nimbus-7 satellite, were stored on a Radiance Archive Tape (RAT). RAT data was used to derive a series of products, two of which are held here. Firstly, the LIMS Inverted Profile Archival Tape (LAIPAT). This dataset contains radiances (from RAT), which are used to derive daily inverted profiles of temperature.

RAT data was used to derive a series of products, two of which are held here. Firstly, the LIMS Inverted Profile Archival Tape (LAIPAT). This dataset contains radiances (from RAT), which are used to derive daily inverted profiles of temperature, and mixing ratios, water vapour, nitric acid, and nitrogen dioxide. Profiles are geolocated. Secondly, the LIMS Map Archival Tape (LAMAT). This dataset was processed to create daily maps in the form of Fourier coefficients for each parameter at 18 pressure levels (from 0.05 to 100 mbar). Data are organised into 38 4 deg. latitude bands. Data for the daily maps are interpolated to the two synoptic time (0000 GMT for night and 1200 GMT for day). Also included is the day/night combined (averaged) data. This dataset is public. Please note that a major reprocessing of the Nimbus 7 LIMS data has recently been completed. The purpose of these activity was to take advantage of the changes in the spectral line parameters that have occurred since the original archived version was created and to generate a data version that is compatible with the UARS data sets. Improvements in the algorithm have also been made. More information is available from the LIMS homepage at http://lims.gats-inc.com/ and version 6 data can be downloaded from GES DAAC.
