Abstract: A method includes receiving data indicative of properties of a substrate support from one or more sensors of a removable sensor assembly disposed proximate to the substrate support. The method further includes providing data based on the data indicative of properties of a substrate support to a physics-based model of the substrate support. The method further includes receiving predicted performance data of the substrate support from the physics-based model.

Abstract: Systems, devices and methods including a handheld sensing device comprising: a sensor configured to measure ambient methane, ethane, propane, butane, and/or pentane concentrations; and a handle, where the sensor is disposed on a first end of the handle; control electronics comprising: a processor having addressable memory, the processor in communication with the sensor, where the processor is configured to: receive the measured ambient gas concentrations; and detect elevated ambient gas concentrations that may be attributed to a natural gas emissions source based on the measured ambient gas concentrations.

Abstract: Systems, devices, and methods including a processor having addressable memory, the processor configured to: receive an unmanned aerial vehicle (UAV) data packet, where the UAV data packet comprises methane concentration data and UAV information from a UAV flight path; receive at least one Meteorological data packet, where the Meteorological data packet comprises weather data; combine the UAV data packet with a nearest Meteorological data packet; and determine a methane emission rate of a methane source based on the combined UAV data packet and the nearest Meteorological data packet.

Abstract: Systems, devices, and methods for receiving, by a ground control station (GCS) having a processor with addressable memory, a plurality of point source gas concentration measurements; receiving, by the GCS, a meteorological data corresponding to each point source concentration gas measurement; determining, by the GCS, if each point source gas concentration measurement is an elevated ambient gas concentration; generating, by the GCS, a back trajectory for each elevated ambient gas concentration; storing, by the GCS, the position of each generated back trajectory in a grid; determining, by the GCS, a probability of a gas source location corresponding to the stored positions in the grid; and generating, by the GCS, an overlay showing the probability of the gas source location.

Abstract: Systems, devices, and methods including a processor having addressable memory, the processor configured to: receive a trace-gas data packet, where the trace-gas data packet comprises a trace-gas concentration data from a trace-gas sensor and a location data for the trace-gas sensor from a location sensor, where the location data for the trace-gas sensor comprises a trajectory of the trace-gas sensor in space; receive at least one Meteorological data packet from one or more weather stations, where each weather station is distal from the trace-gas sensor, where each weather station generates a corresponding Meteorological data packet, where each Meteorological data packet comprises weather data; combine the trace-gas data packet with a selected spatial and temporal Meteorological data packet; and determine a trace-gas emission rate of a trace-gas source based on the combined trace-gas data packet and the selected Meteorological data packet.
