World Meteorological Organization (WMO) and its member nations have recognized the need to understand and control the increasing influence of human activity on the global atmosphere. WMO's Global Atmosphere Watch (GAW) defines the application and maintenance of global, long-term observations of the chemical composition and selected physical characteristics of the atmosphere with emphasis on quality assurance and control.

The socio-economic consequences of that influence affect human and ecosystem health, water quality, water supply and agricultural production, among others. This urged the definition of concrete actions to face the challenges related to stratospheric ozone depletion, changes in weather and climate related to atmospheric amounts of greenhouse gases and aerosols, and the risks of air pollution and its transport and deposition.

In support of the sciences related to Atmospheric Monitoring, at IES we provide state-of-art Air Quality Monitoring solutions such as:

• Trace Gas Detection including Greenhouse Gases,
• Portable Gas Analyzers, and
• Stack, Duct and Tunnel optical flow meters

IES also supports the monitoring of emissions into the atmosphere from industrial activities with the supply of measurment systems such as high-accuracy air flow sensors for stacks, ducts and channels and long-base flow sensors for ambient safety in Aluminium smelters.
