Linköping University uses a drone with a high-performance methane sensor to map and find methane emission sources. Sparv Embedded equipped the drone with sensors. The Sparvio system takes onboard readings of a range of parameters: methane, winds, air pressure, position, orientation and speed, temperature and humidity and also reads flight data from the drone itself. All data is timestamped and logged onboard. The data is also transmitted to a ground station via radio, where the operator can view graphs during and after the flight.
This article in ACS Earth and Space Chemistry describes results as of 2021. Among other results, the authors found that wind measurements onboard the drone revealed wind variations not present at ground-based weather stations.
Methane is an important greenhouse gas and the current knowledge of emission sources is lacking. Sparv Embedded is happy to help Linköping University and others to develop methods to explore the emissions. We continue to refine our solution in this area.
We are a European reseller of Aeris Technologies supporting their high-resolution sensors for methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), nitrous oxide (NO2), etc. We are also a reseller of the unique Anemoment wind sensors.
