We have made measurements using an electric, zero emissions, remote control model aircraft equipped with a compact methane sensor to quantify CH4 emissions around near-field gas and oil facilities. The remote control aircraft can sample much closer to local sources than conventional manned craft and higher maneuverability.
The scientific objectives are to address the following questions:
What are CH4 plume sizes and magnitudes from gas/oil facilities?
What are the spatial and temporal characteristics of the CH4 plumes?
What are the emissions of methane from these sources?
- Between 1901–2012, “almost the entire globe has experienced surface warming… Each of the last three decades has been successively warmer at the Earth’s surface than any preceding decade since 1850.”
- ”The rate of sea level rise since the mid-19th century has been larger than the mean rate during the previous two millennia…. It is virtually certain that global mean sea level rise will continue beyond 2100.”
- ”Atmospheric concentrations of CO2, methane, and N2O have increased to levels unprecedented in at least the last 800,000 years….Most aspects of climate change will persist for many centuries even if emissions of CO2 are stopped.”
- “Heat waves are very likely to occur more frequently and last longer…. Extreme precipitation events…will very likely become more intense and more frequent by the end of this century.”
- ”A nearly ice-free Arctic Ocean in September before mid-century is likely.”
- “Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system…. Limiting climate change will require substantial and sustained reductions of greenhouse gas emissions.”

What if predicting the flu was as common as forecasting the weather? That’s the concept behind Sickweather, a Baltimore start-up that mines public data from Facebook and Twitter for key words and phrases about symptoms of sickness. The Signal’s Lisa Morgan interviews Sickweather’s Graham Dodge. News link is http://www.wypr.org/podcast/5313-cloudy-chance-influenza
This study is also utilizing our machine learning approach.
