Single-footprint retrievals for AIRS using a fast TwoSlab cloud-representation model and the SARTA all-sky infrared radiative transfer algorithm
(Copernicus GmbH, 2018)
One-dimensional variational retrievals of temperature and moisture fields from hyperspectral infrared (IR) satellite sounders use cloud-cleared radiances (CCRs) as their observation. These derived observations allow the ...
Non-Gaussian Analysis of Observations from the Atmospheric Infrared Sounder Compared with ERA and MERRA Reanalyses
(American Meteorological Society (AMS), 2017-05-17)
Statistical relationships between higher-order moments of probability density functions (PDFs) are used to analyze top-of-atmosphere radiance measurements made by the Atmospheric Infrared Sounder (AIRS) and radiance ...
Creating a Single Radiance Climate Record from AIRS, IASI and CrIS
We investigate three key aspects for creating a climate record from multiple hyperspectral infra-red sensors. The motivation is to produce a multi-decade continuous record of global radiance measured leaving the atmosphere. ...
A 4‐year zonal climatology of lower tropospheric CO₂ derived from ocean‐only Atmospheric Infrared Sounder observations
(American Geophysical Union, 2008-09-20)
A 4‐year zonally averaged climatology of atmospheric CO₂, ocean only, between ±60° latitude has been derived from the Atmospheric Infrared Sounder (AIRS) radiances. Using only very clear fields of view, the CO₂ profile in ...
Two-year comparison of radiances from the Atmospheric Infrared Sounder (AIRS) and the Infrared Atmospheric Sounding Interferometer (IASI)
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2009-08-12)
The radiometric intercomparison of instruments is a key element in developing climate-quality data records. In this study we compare data from the first two years of the Infrared Atmospheric Sounding Interferometer (IASI) ...
Spectral calibration in hyperspectral sounders
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2009-08-21)
It is widely accepted that the knowledge of the frequencies of the spectral response functions (SRF) of the channels of hyperspectral sounders at the 10 parts per million (ppm) of frequency level is adequate for the retrieval ...
