REFERENCE MODEL FOR CH4 AND N2O AND TRENDS

Conference item

Data from the Stratospheric and Mesospheric Sounder on Nimbus 7 have been used as the basis for a model of the abundances of nitrous oxide and methane in the stratosphere. A version of this was produced two years ago (Taylor, Dudhia and Rodgers, /1/ - hereafter called paper 1) and in this new paper we consider some of the possible error sources in more detail, as well as long-term trends. The principal source of error in the SAMS retrievals is thought to be the use of climatological ozone profiles to invert the temperature profile data. However, we find that the effect is too small, and of the opposite sign, to explain the discrepancies between satellite and in-situ measurements, noted in paper 1. As expected, no systematic trends which exceed the estimated error in the data are found in either methane or nitrous oxide. © 1989.
