Low-Cost Hab Platform To Measure Particulate Matter In The Troposphere, Mark J. Potosnak, Bernhard Beck-Winchatz, Paul Ritter
Low-Cost Hab Platform To Measure Particulate Matter In The Troposphere, Mark J. Potosnak, Bernhard Beck-Winchatz, Paul Ritter
2017 Academic High Altitude Conference
High-altitude balloons (HABs) are an engaging platform for formal and informal STEM education. However, the logistics of launching, chasing and recovering a payload on a 1200 g or 1500 g balloon can be daunting for many novice school groups and citizen scientists, and the cost can be prohibitive. In addition, there are many interesting scientific applications that do not require reaching the stratosphere. In this poster presentation we discuss a novel approach based on small (30 g) balloons that are cheap and easy to handle, and low-cost tracking devices (SPOT and 900 MHz spread spectrum) that do not require a …

A High-Altitude Balloon Platform For Determining Regional Uptake Of Carbon Dioxide Over Agricultural Landscapes, Angela M. Bouche
2017 Academic High Altitude Conference
Interactions between the biosphere and atmosphere are an important part of the global carbon cycle, and quantifying the carbon dioxide exchanges between them is helpful in predicting the uptake of carbon dioxide from anthropogenic sources by the biosphere in the future. In the Midwestern United States, agricultural systems cover a large part of the landscape, so understanding their role in influencing the global carbon budget is crucial as anthropogenic sources of carbon dioxide grow larger. Carbon dioxide exchanges can be measured by eddy covariance at the ecosystem level (bottom-up approach) or regionally by inversion techniques (top-down approach). Here we describe …
