Global ozone forecasting
The availability of near-real time ozone observations from satellite instruments has recently initiated the development of ozone data assimilation systems. In this paper we present the results of an ozone assimilation and forecasting system, in use since Autumn 2000. The forecasts are produced by an ozone transport and chemistry model, 5 driven by the operational medium range forecasts of ECMWF...
متن کاملGlobal Transport of Ozone
The three principal ~chanisD8 for large scale atmospheric transport of tropospheric ozone [injection from the stratosphere, transport from regions of net production in the boundary layer and distribution of °3 precursors resulting from either stratospheric injection or surface emissions] are examined in the light of current observations. While the actual °3 climatology may be much more complex ...

متن کاملA global tropospheric ozone climatology from trajectory-mapped ozone soundings
A global three-dimensional (i.e. latitude, longitude, altitude) climatology of tropospheric ozone is derived from the ozone sounding record by trajectory mapping. Approximately 52 000 ozonesonde profiles from more than 100 stations worldwide since 1965 are used. The small number of stations results in a sparse geographical distribution. Here, forward and backward trajectory calculations are per...
متن کاملSurface Ozone Measurements from a Global Network
From a network of sites, primarily in the Atlantic and Pacific Ocean regions, measurements of the surface ozone concentration yield information on the seasonal, synoptic, and diurnal patterns. These sites, generally removed from the effects of local pollution sources, show characteristics that typify broad geographical regions. At Barrow, AK; Mauna Loa, HI; American Samoa; and South Pole, data ...
