1. A method for generating information about a system, wherein the system comprises a data management platform, a first reference gas monitor positioned at a first reference gas monitor location, a first gas sensor node, and a second gas sensor node, the method comprising:
positioning the first gas sensor node at a first gas sensor node location that is within a distance limit of the first reference gas monitor location;
positioning the second gas sensor node at a second gas sensor node location, wherein the second gas sensor node location is further away from the first reference gas monitor location than the first gas sensor node location is from the first reference gas monitor location;
periodically gathering over a time interval, using the first reference gas monitor, gas quality measurement data for the first reference gas monitor location;
periodically gathering over the time interval, using the first gas sensor node positioned at the first gas sensor node location, gas quality measurement data for the first gas sensor node location;
calculating, using the data management platform, a calibration profile for the first gas sensor node based on:
the gathered gas quality measurement data for the first reference gas monitor location; and
the gathered gas quality measurement data for the positioned first gas sensor node location;
applying the calculated calibration profile to gas quality measurement data gathered by the second gas sensor node positioned at the second gas sensor node location to obtain calibrated gas quality measurement data for the second gas sensor node location; and
storing the calibrated gas quality measurement data for the second gas sensor node location in storage media of the system.
