The Limb Infrared Monitor of the Stratosphere (LIMS) version 6 Level-3 data product consists of daily, 2 degree zonal Fourier coefficients, of vertical profiles of temperature, geopotential height, and mixing ratios of ozone (O3), nitrogen dioxide (NO2), water vapor (H2O), and nitric acid (HNO3). The data are on 28 pressure levels, equally spaced logarithmically, between 316 hPa and 0.01 hPa. Version 6 LIMS data have improved accuracy and precision of measured geophysical parameters.

The data files are in an ASCII text format compressed using gzip. The LIMS instrument was launched on the Nimbus-7 satellite and was operational from 25 October 1978 until May 28, 1979.

These data supercede the previous version 5 products, known as the LIMS Map Archival Tape (LAMAT) and the LIMS Seasonal Map Archival Tape (LASMAT).
