Greenhouse gas emissions caused by human activities remain one of the most important subjects of internationaldiscussions. The routine gas flaring has been estimated to be responsible for as much as 1% of global carbon dioxideemission per year. Gas flaring analysis is one of the key-interest subjects in remote sensing community. Some of theexisting publications use remote sensing techniques with satellite imagery to derive information about flame temperatureand further about to estimate the volume of the flared gas. The often missing element is an in-situ measurement analysisof gas flames, combining signals recorded by a camera on-ground and data on flared gas volume, temperature and gastype. In order to address this problem, an experiment was conducted, in which the gas flame was recorded by thermalcameras on-ground, simultaneously to an aerial survey and the gas flow was measured at the same time on-ground. Themeasurement setup was designed in cooperation between Institute of Optical Sensor Systems of German AerospaceCenter (DLR) and German Federal Institute for Materials Research and Testing (BAM). Cameras recording in thermaland mid-wave IR wavelengths were used to record the burning gas on-ground and from the aerial survey. All themeasurements have been compared and statistically analysed with respect to the recorded temperature. The purpose ofthe examination was to describe the signal changes in thermal imagery with respect to changes in energy, emitted by theburning process. This approach will allow for later calculation of the amount of energy in form of thermal radiation sentfrom the flame to the satellite.
