The Extech Desktop Indoor Air Quality CO2 Monitor checks for carbond dioxide concentrations through the maintenance free NDIR CO2 sensor. Indoor air quality is displayed in ppm with good (0 to 800ppm), normal (800 to 1200ppm), and poor (>1200ppm) indications. A programmable visible and audible CO2 warning alarm will alert users if extreme readings are detected. Measurement ranges are 0 to 9,999ppm for CO2, 14 to 140°F for temperature, and 0.1 to 99.9% for relative humidity.
Applications include air quality monitoring in schools, office buildings, greenhouses, factories, hotels, hospitals, transportation lines, and anywhere that high levels of carbon dioxide are generated.

Flux towers track CO2 exchange between forests and atmosphere
Determining exchange rates of carbon dioxide between the earth’s forests and the atmosphere is turbulent business. 
 Wind above forest canopies swirls as vortexes of air enter and exit stands of trees. Across the globe, towers stand among the landscape, with sensors monitoring these eddies for carbon dioxide, water vapor and other gasses. These so-called “flux towers” collect data on carbon dioxide exchange rates between the earth and atmosphere. 
 Information gathered plays into the debate on the measurable effects of climate change. 
 Carbon dioxide flows between the earth, atmosphere and ocean in an attempt to reach equilibrium. As automobiles and energy production facilities burn fossil fuels, more carbon dioxide joins to the mix.

Long-standing environmental monitoring programs have the power to support a large number of research initiatives and policy changes—however, actually starting these networks can prove challenging. Not only is starting the program difficult, but keeping things operational for decades to come has also been challenging for environmental professionals hoping to make an impact with applied research. 
 
Jason Polk, Professor of Environmental Geoscience and Director of the Center for Human GeoEnvironmental Studies (CHNGES) at Western Kentucky University, is all too familiar with this process.

The prairies of Saskatchewan can be described as one of the least water-secure parts of Canada, making water quality monitoring essential for informed resource management in a region already facing water insecurity. While natural physical properties worsen some of the poor water quality conditions in the region, others are connected to land use. 
 
Having grown up spending summers on the shores of Lake Huron, Helen Baulch, an associate professor at the School of Environment and Sustainability at the University of Saskatchewan , has always been dedicated to the protection of water resources. 
 
Looking back fondly at her childhood playing along the shore, Baulch also recalls the invasion of quagga mussels during her teenage years and watching the lake change as a result.
