Recently, satellite observations have been used to identify large emission events from oil and gas sources. For example, used the Sentinel-2 MultiSpectral Instrument to quantify emissions from a well pad in Algeria and a compressor station in Turkmenistan, and consistently estimated average emission rates of multiple tons per hour. Also in Turkmenistan, used three different satellite data sets to detect 29 events with emission rates >1800 kg/hr in the period between 2017 and 2020. Most current detections of individual emission events using satellite data are limited to emission rates in excess of 1000 kg/h, however, new satellite-based instruments are expected to reduce detection limits significantly. provide a review of the expected capabilities of satellite measurements to detect events. For point sources, events with emissions on the order of ~100 kg/hr could be detected by satellite imagers, whereas the detection threshold increases to ~1000 kg/hr for regional mappers.
