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.\nPAYLOAD WEIGHT AND INTERFACE\nTo 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.\nMEASUREMENT APPROACH\nMeasurements 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.\nTo give an example of the intention;\nAt 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).\nAt timestamp 2, (1 second in the future, if operating at 1 Hz), a new volume of air V2 is ingested and analysed to give measurements of N2O(t=2), CO2 (t=2) and CH4(t=2).\nAnd so on, at the ‘Hz’ rating the device operates at.\nMeasurement must be conducted in-situ/in-flight at real time while the UAV operates; storing volumes of air for after-operation analysis would not be suitable.\nCONCLUSION\nAfter a market evaluation it is believed there is only one solution which can fulfil the combined requirements – the Aeris Sensors MIRA Strato.
