Driving a single CTM with different analyses: impact on solar heating, photolysis rates and chemical lifetimes

The BASCOE CTM can currently be driven by 3 different sets of meteorological analyses: ECMWF operational products, ERA-Interim reanalyses and Canadian operational products. We will show the impact of these different analyses on photodissociation rates, photochemical lifetimes and solar heating rates in the stratosphere. In a first step this sensitivity study is done for one-month periods representative of solstice (January 2011) and equinox conditions (April 2011).
