Accurate Determination of Trace Gas Sources:
We make accurate in situ measurements of trace atmospheric gases such as CH4, C2H6, CO2, and O3. Our skilled team of scientists can carefully design the flight tracks, analyze the data, and apply budget techniques to the processed data to estimate the magnitude and location of these trace gas sources. Since much of the analysis is automated, we can provide source estimates almost immediately after a flight.
How we do it:
Understanding the size and location of trace gas emissions is the first step in remediation. Aircraft are often the optimal 3 dimensional research platform to do this. For example, by flying set of upwind and downwind legs throughout the atmospheric boundary layer the integrated changes in concentration within the enclosed volume, which is equal to the total source/sink within the volume, can be estimated almost immediately after a flight. We have the expertise and experience to optimize the flight strategy, carry out the analysis and estimate the errors in the source/sink estimates.
Scientific Aviation operates three fixed-wing, single-engine Mooney aircraft that have been carefully configured for atmospheric research. Air inlets have been installed on the outboard section of the wing, well away from the exhaust and propeller induced turbulence. In addition to trace gas measurements, supporting measurements include wind speed and direction, temperature, humidity, 3-dimensional location and time.
The three aircraft have interchangeable scientific payloads and 1200 watts of 110V 60 Hz power, but differ in terms of flight capability. All aircraft are fully FAA certified. A normal flight crew consists of a pilot and a flight scientist. Read about our team. Which airplane and payload are right for your project?
