2. Greenhouse gas monitoring - Wikipedia

   en.wikipedia.org/wiki/Greenhouse_gas_monitoring

   Greenhouse gas monitoring is the direct measurement of greenhouse gas emissions and levels. There are several different methods of measuring carbon dioxide concentrations in the atmosphere, including infrared analyzing and manometry. Methane and nitrous oxide are measured by other instruments.

3. Atmospheric methane - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_methane

   Methane concentration at NOAA's Mauna Loa observatory through July 2021: A record-high of 1912 ppb was reached in December 2020. [44] CH 4 has been measured directly in the environment since the 1970s. [45] [11] The Earth's atmospheric methane concentration has increased 160% since preindustrial levels in the mid-18th century. [11]

4. Headspace gas chromatography for dissolved gas measurement

   en.wikipedia.org/wiki/Headspace_Gas...

   One of the most widely used methods for headspace analysis is described by the United States Environmental Protection Agency (USEPA). Originally developed by the R.S. Kerr USEPA Laboratory in Ada, Oklahoma as a "high quality, defendable, and documented way to measure" methane, ethane, and ethene, [7] [8] RSKSOP-175 is a standard operating procedure (SOP) and an unofficial method employed by ...

5. Carbon monitoring - Wikipedia

   en.wikipedia.org/wiki/Carbon_monitoring

   Carbon monitoring as part of greenhouse gas monitoring refers to tracking how much carbon dioxide or methane is produced by a particular activity at a particular time. For example, it may refer to tracking methane emissions from agriculture, or carbon dioxide emissions from land use changes, such as deforestation, or from burning fossil fuels, whether in a power plant, automobile, or other device.

   The world saw a record jump in levels of methane in the atmosphere last year as the main heat-trapping greenhouse gases reached new highs, UN experts said.

7. Tunable diode laser absorption spectroscopy - Wikipedia

   en.wikipedia.org/wiki/Tunable_diode_laser...

   Tunable diode laser absorption spectroscopy (TDLAS, sometimes referred to as TDLS, TLS or TLAS [1]) is a technique for measuring the concentration of certain species such as methane, water vapor and many more, in a gaseous mixture using tunable diode lasers and laser absorption spectrometry.
