Description
SUMMARY The University of Edinburgh Field Spectroscopy Facility requires a sensor system/analyser with the capability to measure N2O (nitrous oxide), CO2 (carbon dioxide) and CH4 (methane) concentrations at altitude/height simultaneously and in real time, at a detection limit in the <1 ppb for methane, <0.5 ppb for N2O and < 200 ppb for CO2. The concentrations are required for flux measurements, and therefore the temporal frequency of measurements is important, measurement frequency needs to be no less than 1 Hz, ideally at 5 Hz. PAYLOAD WEIGHT AND INTERFACE To enable use of the facility’s existing UAV equipment the sensor must be able to interface with a DJI M400 drone, and the total sensor weight must be under 7kg. MEASUREMENT APPROACH Measurements of these gasses must be made simultaneously, to a synchronised timing and measurement frequency, and the measurement at a given timestamp should be taken from the same shared volume of air. This should produce a single combined data series. To give an example of the intention; At timestamp 1, a volume of air, V1, has been ‘ingested’, and will be tested by the analyser to give measurements of N2O(t=1), CO2 (t=1) and CH4(t=1). At timest…
