The SnifferDRONE | Sniffer Robotics
WEBThe patented* SnifferDRONE is an unmanned aerial system (UAS) useful for collecting land-based emissions data over large areas. The tool automates the method that is otherwise performed manually, referred to as surface emissions monitoring (SEM) providing a safer, more efficient, more effective, and comprehensive s ystem s olution.
How are Surface Emissions Measured? | QED Environmental Systems
WEBSurface emission monitoring refers to techniques which measure the levels of landfill gases released at a surface level. These methods may either be instantaneous or integrated. Instantaneous monitoring refers to measuring emissions of methane on the landfill surface at a given time and location.
What is Surface Emissions Monitoring? - Sniffer Robotics
WEBSurface emissions monitoring (SEM) describes a method for measuring gas emissions at or near ground surfaces. The term is most commonly referred to the method of detecting methane emissions over the surface of a landfill, but can also apply to monitoring methane emitted from buried natural gas pipelines, measuring methane …

WEBThe new Tier 4 process requires the completion of four quarters of instantaneous surface emission monitoring (SEM) with no exceedance of the 500 parts per million by volume (ppmv) threshold, measured as methane, followed by an annual report, and then ongoing quarterly SEM with no exceedances for active sites.
Surface Emissions Monitoring Solutions | QED Environmental Systems
WEBThe latest portable hand-held laser based technology, SEM 5000 provides a more accurate, responsive and intrinsically safe method for surface emissions monitoring. SEM5000 is selective, specifically to methane and is able to detect emissions from 0.5ppm to 100% concentration.
EPA Approves Drone-Based Landfill Methane Emissions Monitoring
WEBJan 26, 2023 · Certain landfills are required to perform surface emissions monitoring (SEM) procedures on a quarterly basis to demonstrate compliance with the 500 parts per million (ppm) above background concentration operational standard at …
US EPA Approves the SnifferDRONE™ for Monitoring Landfill Methane Emissions
WEBDec 22, 2022 · The US EPA approval allows the SnifferDRONE to be used as a pre-screening emissions monitoring tool for quarterly compliance purposes. The adoption of the OTM-51 method provides standardization in application method and reporting, helpful in driving better consistency in performance.
New solutions for landfill surface emissions monitoring
WEBMar 14, 2021 · The regulations require that landfills perform surface emission monitoring (SEM) to identify potential emission exceedances. Several technologies are used for conducting SEM, including flame ionization detectors (FIDs) and photoionization detectors (PIDs); however, new tunable diode laser absorption spectroscopy (TDLAS) technology can …
Understanding landfill gas monitoring techniques - Waste Today
WEBFeb 13, 2019 · Surface emission monitoring (SEM) is a technique that involves using a portable methane meter near the landfill’s surface to measure concentrations while traversing the site.
