Study of tropospheric ozone concentration trend of Kermanshah by meteorological parameter and ozone precursor and OMI images

Abstract: Clean air is a necessity for human well-being and health. Air pollution is a major threat to humans and other organisms and is considered as one of the environmental challenges. Today, with the increase in air pollution, the need to know more about the causes of its occurrence has been raised. The various consequences of air pollution have made air quality monitoring and control inev...

Ozone chemistry in aqueous solution -Ozone decomposition and stabilisation

Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. Additives can either accelerate the decomposition rate of ozone or have a stabilising effect of the ozone decay. By contro...

Ozone diagnostic

Nitrogen oxide (NO x =NO+NO 2) emissions from various sources contribute to the ozone budget. The identification of these contributions is important, e.g. for the assessment of emissions from traffic. The non-linear character of ozone chemistry complicates the online diagnosis during multi-decadal chemistry-climate simulations. A methodology is 5 suggested, which is efficient enough to be incor...

Monitoring of Sciamachy Total Column Ozone Using the Dao Ozone Data Asssimilation System

The total column ozone data from SCIAMACHY were monitored in the ozone data assimilation system at NASA’s Data Assimilation office (DAO). The ozone data from NOAA−16 Solar Backscatter UltraViolet/2 (SBUV/2) instrument are assimilated in the DAO’s system. The monitoring consists of computing the differences between SCIAMACHY observations and the ozone system forecast, i.e. observed−minus−forecas...
