RISThe Effects of Surface Longwave Spectral Emissivity on Atmospheric Circulation and Convection over the Sahara and Sahel
Publisher: American Meteorological Society
Abstract: AbstractThis study quantifies the impact of the inclusion of realistic surface spectral emissivity in the Sahara and Sahel on the simulated local climate and beyond. The surface emissivity in these regions can be as low ...
A Neural Network–Based Cloud Mask for PREFIRE and Evaluation with Simulated Observations
Publisher: American Meteorological Society
An Observationally Based Global Band-by-Band Surface Emissivity Dataset for Climate and Weather Simulations
Publisher: American Meteorological Society
Abstract: hile current atmospheric general circulation models (GCMs) still treat the surface as a blackbody in their longwave radiation scheme, recent studies suggest the need for taking realistic surface spectral emissivity into ...
Comparisons of Clear-Sky Outgoing Far-IR Flux Inferred from Satellite Observations and Computed from the Three Most Recent Reanalysis Products
Publisher: American Meteorological Society
Abstract: he far-IR spectrum plays an important role in the earth?s radiation budget and remote sensing. The authors compare the near-global (80°S?80°N) outgoing clear-sky far-IR flux inferred from the collocated Atmospheric Infrared ...

A Physically Based Algorithm for Non-Blackbody Correction of Cloud-Top Temperature and Application to Convection Study
Publisher: American Meteorological Society
Abstract: loud-top temperature (CTT) is an important parameter for convective clouds and is usually different from the 11-?m brightness temperature due to non-blackbody effects. This paper presents an algorithm for estimating ...
A Radiative–Convective Equilibrium Perspective of Weakening of the Tropical Walker Circulation in Response to Global Warming
Publisher: American Meteorological Society
Abstract: oth observational analysis and GCM simulations indicate that the tropical Walker circulation is becoming weaker and may continue to weaken as a consequence of climate change. Here, the authors use a conceptual radiative?convective ...
Direct Influence of Solar Spectral Irradiance on the High-Latitude Surface Climate

Improved Representation of Surface Spectral Emissivity in a Global Climate Model and Its Impact on Simulated Climate
Publisher: American Meteorological Society
Abstract: AbstractSurface longwave emissivity can be less than unity and vary significantly with frequency. However, most climate models still assume a blackbody surface in the longwave (LW) radiation scheme of their atmosphere ...
A Global Climatology of Outgoing Longwave Spectral Cloud Radiative Effect and Associated Effective Cloud Properties
Publisher: American Meteorological Society
Abstract: ongwave (LW) spectral flux and cloud radiative effect (CRE) are important for understanding the earth?s radiation budget and cloud?radiation interaction. Here, the authors extend their previous algorithms to collocated ...
