Thermospheric/Ionospheric Extension of the Whole Atmosphere Community Climate Model
2007Abstract : A key question in space weather and space environment study is to understand and to quantify the contribution to thermospheric/ionospheric variability by processes from both the lower atmosphere and from the magnetosphere and solar input. The primary goal of this project is address this question by developing a model that encompasses the ...

Communication-Avoiding for Dynamical Core of Atmospheric General Circulation Model
Proceedings of the 47th International Conference on Parallel Processing, 2018Dynamical core is one of the most time-consuming parts in the global atmospheric general circulation model, which is widely used for the numerical simulation of the dynamic evolution process of global atmosphere. Due to its complicated calculation procedures and the non-uniformity of latitude-longitude mesh, the parallelization suffers from high ...

Modeling The Atmosphere As An Unguided Optical Communications Channel
SPIE Proceedings, 1989Due to the increasing number of applications for optical communications, methods such as computer simulation are needed for the performance analysis of these systems. The objective of this paper is to propose a system level model for simulating the Earth's atmosphere as an unguided optical communications channel.

Atmosphere Propagation and Communication Channel Model for Laser Wavelengths
IEEE Transactions on Communications, 1970The advent of the laser has generated much interest in its use for communication. Consideration is given in this paper to obtaining a communication channel model of the atmosphere for laser frequencies. For this purpose a fairly exhaustive, tutorial, and partly critical review of a major part of the extensive literature pertaining to theoretical and ...

A New Moist Turbulence Parameterization in the Community Atmosphere Model
Journal of Climate, 2009Abstract A new moist turbulence parameterization is presented and implemented in the Community Atmosphere Model (CAM). It is derived from Grenier and Bretherton but has been heavily modified to improve its numerical stability and efficiency with the long time steps used in climate models. A goal was to provide a more physically realistic

This chapter addresses the problem of multimodal analysis of human face-to-face communication. This is imporant since in the near future, smart environments equipped with multiple sensory systems will be able to sense the presence of humans and assess recognize their behaviours, actions, and emotional states.

Deep Learning based cloud parametrization for the Community Atmosphere Model
2020<p>Despite significant progress in climate modeling over the last decades, the spread in simulated equilibrium climate sensitivity, i.e. the change in global mean surface temperature after a doubling of atmospheric CO2 concentrations, has not decreased since the 1970s.
