Finite Element Model for Atmospheric IR-Absorption
نویسنده
چکیده
The updating concerns mainly the sensitivity analysis. The model is not anymore monochromatic, the system matrix K is now calculated separately for the two contributions water vapor and CO2 : K=KH2O+KCO2. The contribution of 0.04 % CO2 is small as compared to the contribution of 3.5 % water vapor: for the global and annual mean evacuation the contributions of CO2 and water vapor could be dealt with in a monochromatic model. However, for the sensitivity analysis the two contributions have to be dealt with separately. The surface sensitivity for doubling CO2 concentration from 0.04% to 0.08% is now 0.03 °C.

Three-dimensional thermal and radiometric models have been developed to study the passive IR signature of a land mine. A finite element model is used to describe the thermal phenomena, including temporal variations, the spatial structure of the signature, and enviromental effects. The Crank-Nicholson algorithm is used for time-stepping the simulation. The mine and the surroundings are approxima...
