Self-consistent retrieval of pressure/temperature and CO2 densities in the MLT from the SABER/TIMED limb radiances in the 15 and 4.3 μm channels
Abstract
The SABER/TIMED broadband infrared limb observations of the mesosphere and lower thermosphere (MLT) are providing important information about the composition and energy budget of this atmospheric region. However, until now the SABER/TIMED pressure and temperature were retrieved using radiances measured in the 15 µm CO2 band in combination with the WACCM model CO2 distribution. The SABER v2.0 operational processing uses a rigorous non-LTE, self-consistent, two-channel, simultaneous retrieval of pressure, temperature and CO2 density from SABER daytime broadband limb 15 and 4.3 µm radiances. Three years of simultaneous temperature/CO2 profiles have been produced thus far in a post processing mode. Results from these retrievals for various latitudes and seasons as well as their comparisons with other observations and model results are discussed.
