Ky. Kondratyev et Ca. Varotsos, Global tropospheric ozone dynamics - Part II: Numerical modelling of tropospheric ozone variability - Part I: Tropospheric ozone precursors [ESPR 8 (1) 57-62 (2001)], ENV SCI P R, 8(2), 2001, pp. 113-119
Various causes of tropospheric changes have been considered in Part I in co
nnection with the analysis of observation data. It is clear however, that t
he principal instrument for understanding numerous and often interacting ca
uses of ozone changes is numerical modelling. A review of the current statu
s of the numerical modelling has been made for the variability of the ozone
concentration in the troposphere. Observation data on tropospheric ozone a
nd relevant numerical modelling results show that a necessity exists to get
more adequate global observational data.
