Recently an interesting article found its way to my desk. It is titled ‘How Will the Stratosphere Affect Climate Change?’ and is in the June 15th 2007 issue of Science Magazine (Volume 316, Page 1576).

Forcing in the Stratosphere

March 28th, 2007 · No Comments

Recently I read an interesting paper in science magazine titled Anthropegenic and Natural Influences in the Evolution of Lower Stratospheric Cooling by V. Ramaswamy et al. Different atmospheric forcings (natural and anthropogenic) and their degree of influence are analyzed using data and models. NOAA satellites, specifically channel 4 of the microwave sounding unit (MSU), provide [...]
