GML conducts research that addresses three major challenges: greenhouse gas and carbon cycle feedbacks, changes in clouds, aerosols, and surface radiation, and recovery of stratospheric ozone.
As atmospheric greenhouse gas levels continue to rise, it is important to understand the basics of what these gases are, how NOAA monitors them, and what they mean for our global climate. Continue reading to learn all about carbon dioxide and why it keeps making headlines.

Montzka, senior scientist for the Global Monitoring Laboratory, is recognized for his distinguished contributions to the field of atmospheric sciences, particularly for measuring and interpreting trends in greenhouse gas and ozone-depleting substance concentrations worldwide. He is among 26 AAAS Fellows elected from NOAA since 1976.

Scientists from NOAA’s Global Monitoring Laboratory (GML) have undertaken novel development of an uncrewed aircraft system (UAS) “hexacopter” that will enable the lab to not only recommence a long-standing mission that was recently forced to halt, but paves the way toward enhanced operations in the future. The composition of Earth’s atmosphere is rapidly changing due to anthropogenic releases of carbon dioxide (CO2) and methane (CH4), which are powerful greenhouse gasses driving global warming. Also, human-made chemicals such as CFC-11 and CFC-12 (refrigerants) are destroying the ozone layer that filters out ultraviolet (UV) radiation. These CFCs and their counterparts destroy enough of the protective stratospheric ozone layer to produce the Antarctic “Ozone Hole”.
