摘要

A tropospheric chemical forecast system should consist of a reliable description of the dynamical state of the atmosphere, measurements of the global distribution of key chemicals, and realistic emission scenario's. New satellite missions such as Envisat will provide unique information on the columns of several key tropospheric species, e.g. ozone, NO_2, HCHO, CO, CH_4. In this paper we will discuss difficulties in the retrieval of quantitative tropospheric columns of trace gases such as NO_2 from GOME and SCIAMACHY satellite observations. A new integrated retrieval/modelling approach for tropospheric MO_2 is discussed. Secondly, an operational ozone forecast scheme is presented. This system provides meaningful ozone and clear-sky UV distributions for a forecast period of about six days, and can be viewed as a first step towards a chemical forecast system.
