Intercomparison of stratospheric gravity wave observations with AIRS and IASI
Gravity waves are an important driver for the atmospheric circulation and have substantial impact on weather and climate. Satellite instruments offer excellent opportunities to study gravity waves on a global scale. This study focuses on observations from the Atmospheric Infrared Sounder (AIRS) onboard the National Aeronautics and Space Administration Aqua satellite and the Infrared Atmospheric...
متن کاملDerivation of tropospheric carbon dioxide and methane concentrations in the boreal zone from satellite-based hyper-spectral infrared sounders data
Introduction The development of space-borne hyper-spectral IR sounders (AIRS/EOS-Aqua, IASI/MetOp) opens new opportunities for detecting the variations of atmospheric carbon dioxide (CO2) and methane (CH4) concentrations. The capabilities to retrieve atmospheric column-average CO2 mixing ratio and similar column-average CH4 mixing ratio (or CH4 columns) from satellite measurements is of signifi...
متن کاملImproved hurricane track and intensity forecast using single field-of-view advanced IR sounding measurements
[1] Hyperspectral infrared sounders such as the AIRS and IASI provide unprecedented global atmospheric temperature and moisture soundings with high vertical resolution and accuracy. The AIRS and IASI data have been used in global numerical weather prediction models with positive impact on weather forecasts. The high spatial resolution single field-ofview soundings retrieved from AIRS have been ...
متن کاملMapping of the Carbon Dioxide Mid-tropospheric Mixing Ratio and Methane Total Column from Hyperspectral Sounders Data
This paper presents at first an updated status of atmospheric column-average CO2 mixing ratio XCO2 retrieval scheme based on clear-sky or cloud-cleared AIRS/EOS-Aqua data inversion algorithm. Maps of monthly averaged XCO2 estimates have been produced for extensive region of Siberia with spatial averaging about 1.5 x1.5. Similar methodology has been applied for the retrieval of “instant” XCO2 fr...
متن کاملGlobal survey of concentric gravity waves in AIRSimages and ECMWF analysis
Concentric gravity waves (CGWs) are atmospheric phenomena with ring-shape perturbations originating in the troposphere. They can propagate up to the ionosphere and thermosphere and dynamically couple the lower and upper atmosphere. In this study we developed a novel ring detection algorithm to extract CGWs from the Atmosphere Infrared Sounder (AIRS) radiance data and the European Center for Med...
