Anasphere is developing a sensor to measure atmospheric carbon dioxide (CO2) concentration under a NASA Phase I SBIR contract. Presently, there is much concern regarding both atmospheric and aquatic CO2 concentrations due to its significant role in climate change. Currently, there are discrepancies between modeled and measured CO2 fluxes between the atmosphere, water (e.g., oceans, lakes, rivers), and land largely due to lack of direct and accurate measurements of CO2 concentrations. Our goal at Anasphere is to provide an easy to use, inexpensive, and accurate way to measure atmospheric CO2 concentration in order to improve flux estimations. The more calculations that are made, the more likely it is that we will be able to accurately calculate CO2 gas flux between the atmosphere, water, and land and accurately estimate our CO2 sinks and sources. Anasphere's CO2 system can be used in conjunction with our meteorological systems - particularly SmartTetherTM - to yield a more complete atmospheric profile than what has previously been possible.
