Preliminary discussion on some oxidant measurements at Vlaardingen, the Netherlands

摘要: Abstract Measurements of the oxidant level with a Mast-Brewer ozone meter have been made since June 1968 in highly industrialized region Netherlands. Data for summer and autumn are summarized frequency tables. On 11 days exceeded an equivalent concentration 10 p.p.h.m. by mass. these duration sunshine was considerable stable layer occurred below 2000 m; on other hand, 7 during which did not exceed 3 mass there also m, but negligible. Thus, it appears that photochemical production oxidants occurs to extent this area under certain weather conditions. It is shown diurnal variation reverse sulphur dioxide concentration.
