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

Global long-term measurements of Ozone indicate an apparent increase within the past hundred years

Key factors that determine the abundance of O3 in the lower troposphere are:

  • Emissions of the precursors NOx and reactive VOCs
  • Atmospheric production and destruction of O3 (lightning)
  • Turbulent transport (Stratospheric-Tropospheric exchange)
  • Advection from upwind sources
  • Deposition onto surfaces

O3 monitors, in the measurement networks, are mainly point monitors at ground level that yield no information about the vertical distribution of ozone

Vertical profiling measurements are conventionally obtained with balloon-borne sensors. However, this method provides very poor temporal (in most cases 2 measurements/day) and spatial resolution

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)
