Document Summary
Problems: 1 climate response to changes in ozone. Simulations with a general circulation model (gcm) have been used to investigate the climate sensitivity to large changes in atmospheric ozone. Explain qualitatively the results below: a simulation in which all o3 above 30 km altitude is removed shows a large tropospheric warming (+1-3oc) and a very large stratospheric cooling (up to.

The figure below shows terrestrial emission spectra measured from a satellite over northern africa, the mediterranean sea, and and antarctica. The spectra are reported as a function of wavenumber, which is the inverse of wavelength. 142: estimate from the spectra the surface temperature of each region, explain the dips at 600-700 cm-1 (14-16 m m) and 1000-1050 cm-1 (9. 5-10 m m) in the emission spectra for the sahara and mediterranean sea.
