MesopauseIt is the temperature minimum at the boundary between the mesosphere and the thermosphere atmospheric regions.
MesosphereA Layer of atmosphere between the stratosphere and thermosphere (50-85 km above the earth’s surface). This region is situated between the stratopause and the mesopause, in which the temperature generally decreases with height.
Mission LiFE It was introduced by Prime Minister Modi at the COP26 in Glasgow in November 2021. It is an India-led global mass movement that will nudge individual and collective actions towards the protection and preservation of environment.
MistLiquid (water) droplets smaller the 10 micron in diameter suspended in the atmosphere reducing visibility to between 1 and 2 km.
MitigationThe action of reducing the severity, seriousness, or painfulness of something.
Mixing HeightIt is the height to which the lower atmosphere will undergo mechanical or turbulent mixing, producing a nearly homogeneous air mass.
MonitoringTo measure quantitatively or qualitatively the level of a substance over a period of time. The periodic or continuous sampling and analysis of air pollutants in ambient air or from individual pollution sources.
Montreal ProtocolThe Montreal Protocol on Substances that Deplete the Ozone Layer (a protocol to the Vienna Convention for the Protection of the Ozone Layer) is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion.
MutagenicThe ability of a chemical or physical agent to produce heritable changes in the DNA of living cells.
MutationsThe changing of the structure of a gene, resulting in a variant form which may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.
