The importance of Ozone on Earth climate
and Atmospheric radiation balance

In Atmospheric Science, Ozone is considered to be one of the most significant trace gasses. Stratospheric ozone prevents UV solar radiation from reaching the earth’s surface protecting flora and fauna from its harmful effects. Moreover, it contributes to stratospheric warming. On the other hand, tropospheric ozone is considered as anthropogenic greenhouse gas and secondary air pollutant. It is formed by photochemical reactions involving Nitrogen Oxides (NOX) and Volatile Organic Compounds (VOCs)

Impacts of high tropospheric Ozone concentrations

Tropospheric Ozone is an important greenhouse gas, pollutant, and source of OH radicals. It is regarded as the third most important contributor to global warming following Carbon Dioxide and Methane [IPCC 2007]

Tropospheric ozone is known to damage plants, reducing plant primary productivity and crop yield

It is related to the concentration of Methane and other hydrocarbons in the atmosphere through chemical processes assisted by absorption of UV solar radiation

Ozone is also toxic to humans and vegetation because it begins oxidizing biological tissue and causes harmful respiratory effects in cases of long exposure at high concentrations

Ozone contributes to deterioration of materials and buildings affecting monuments of invaluable cultural heritage

Tropospheric Ozone Monitoring

Advantages of
DIAL remote sensing Technique

Continuous monitoring of the vertical distribution of Ozone (24/7 configuration)

Increased raw signal spatial resolution (3.5m – 15m) along with very high temporal resolution (few minutes)

Increased range of measurements typically from 50m up to 12km

Measurements for
Wavelength pairs for DIAL 

266-289nm, O3 measurements within the PBL, (Altitudes<2km)

289-299nm, O3 measurements over the PBL, (Altitudes 2km – 6km)

299-316nm, O3 measurements, (Altitudes 6km – 12km)

Typically, the systematic error in ozone concentration vertical profiles remains lower than 5% (nighttime) and 10% (daytime)

Data acquisition/analysis supported by Raymetrics software:

  • Safe operation even if the user is not familiar to laser technology
  • Fully automated, user friendly, operation and remote control of the system for 24/7 data acquisition
  • Live data processing and display of the retrievals in 2D and 3D imaging
