A Meteorology is the science of weather-related phenomena. See weather, climate.

Methane (CH4) is a hydrocarbon that is a greenhouse gas with a global warming potential most recently estimated at 21. Methane is produced through Anaerobic (without oxygen) decomposition of waste in landfills, animal digestion, decomposition of animal wastes, production and distribution of natural gas and petroleum, coal production, and incomplete fossil fuel combustion.

Methanol (CH3OH) is a colorless poisonous liquid with essentially no odor and little taste. It is the simplest alcohol with a boiling point of 64.7 °C (degrees Celsius).

A Methanotrophic is Having the biological capacity to Oxidize Methane to CO2 and water by metabolism

A Method is a procedure, technique, or tool for performing a scientific activity.

The Method Detection Limit is the minimum concentration of an analyte that undergoes the entire measurement process and can be reported with a stated level of confidence that the analyte concentration is greater than zero.

A Methodology is a documented process or procedure for describing the philosophy of and procedures for performing a sequence of events, such as an analytical process, management of project activities, or the manner in which data are to be evaluated.

Methyl in the environment context refers to a hydrocarbon group, or alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms (–CH₃). This group is a fundamental component of many organic compounds, including various environmental pollutants and some substances that play significant roles in biological systems and industrial applications. In environmental science, the focus often falls on methyl compounds due to their impacts on air and water quality, soil health, and living organisms, including their role in the formation of more complex pollutants.

A methyl bromide is the gaseous compound CH3Br used primarily as an insect fumigant; found to be harmful to the stratospheric ozone layer which protects life on earth from excessive ultraviolet radiation.

A Methyl bromide (CH3Br) is an effective pesticide; used to fumigate soil and many agricultural products. Because it contains bromine, it depletes stratospheric ozone when released to
