Emissions impact climate and air quality
We help find and quantify them
Drone Flux Measurement
A new highly accurate dronebase method of measuring fugitive climate gasses from different sources. Developed by Explicit, the DFM method uses a sniffer drone integrated with high performance gas and wind sensors.
Emissions impact both climate and air quality significantly, yet many of the sources remain scarcely documented. Using the DFM method, we can monitor them correctly and implement the right mitigating actions.
DFM - Key benefits
From climate gas to emissions result
Combining sensors, software and lab services in one integrated solution, Explicit provides a full ISO 17025 compliant service.
Site survey & sampling plan
Preliminary analysis of the site: identification of possible sources, risk zones, feasible flight paths etc. Organization of the campaign.
Drone set-up and data collection
Gas and wind sensors are integrated to the drone. Through an adaptive flight pattern, the drone flights a vertical wall downwind from the site of interest, collecting thousands of data points.
Preliminary and final analysis
An automatized analysis provides the pilot real-time feedbacks on the flight.
Once the data collection is concluded, the analyst processes the data.
A detailed emission report containing the average emission rates and visualizations to support source localization is presented to the client.
Data are collected downwind from the site of interest, so that the emission plume is entirely intercepted by the drone. Because both gas and wind data are closely correlated in time and space, Explicit is able to accurately calculate the net emission rate (kg/h) across the inspected area and provide a consistent representation of the flux density of the gas flowing from the site.
- Final emission rate is calculated using the data collected during at least 3 flights
- 20 % uncertainty in the final result
- Possibility to quantify subsection contributions
