Overview
The Extech Desktop Indoor Air Quality CO2 Monitor checks for carbon 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
Applications include air quality monitoring in schools, office buildings, greenhouses, factories, hotels, hospitals, transportation lines, and anywhere where 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.

Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question.

Stream velocity measurements can be combined with water level measurements to calculate stream flow and chemical parameter loads.

In the eastern basin of Lake Erie, off the coast of Dunkirk, New York, a data buoy collects valuable water quality, weather, and wave data that inform residents and regulatory groups of conditions on the water. 
 
Since 2011, Buffalo State University’s Great Lakes Center has maintained and operated the Dunkirk buoy with funding from the Great Lakes Observing System (GLOS) and field support from the NYSDEC Lake Erie Fisheries Research Unit.
