2. a. How do we use solid angles in satellite meteorology? equator and from the subpoint to 45° west c. The increase in carbon dioxide levels in the atmosphere is contributing to climate change. Which terms would be affected in the Radiative Transfer Equation? Explain your reasoning. d. Discuss what type of satellite imagery or sensors may be useful to monitor climate change? e. Some climate models predict a 2 C temperature change due to the increased CO2 levels. The current average global temperature is is C. Compare the maximum wavelength of the terrestrial radiation now to the maximum wavelength with a 2 C increase in temperature.Explanation / Answer
2 A) The solid angle subtended by a surface S is dened as the surface area of a unit sphere covered by the surface’s projection onto the sphere.2 That’s a very complicated way of saying the following: You take a surface. Then you project it onto a unit sphere (a sphere of radius 1). Then you calculate the surface area of your projection. That’s it. Solid angle is, eectively, a measure of how big an objec tlook sto an observer.
c)Since it is obvious that the cloud cover has a strong influence on the up- and downwelling fluxes in the atmosphere and also on the strength of the GH effect, performed line-by-line radiation transfer (LBL-RT) calculations under different cloudiness conditions, ground temperatures, and humidity to evaluate the influence of CO2 on global warming influence of lineshape effects on RT calculations and their consequences for the ECS.
d)Satellite remote sensing has provided major advances in understanding the climate system and its changes, by quantifying processes and spatio-temporal states of the atmosphere, land and oceans.
Photo interpretation of analog images involves visual inspection and annotation; interpretation of digital imagery expands on this to include complex computer-based numerical processing as well.
