Scientists from Global Monitoring Laboratory contributed to the Bulletin of American Meteorological Society State of the Climate 2020 report report as editors and authors.
GML scientist Glen McConville and Lapenta intern Leah Barkai started the calibration of Dobson World standard instrument D083 at the GML Mauna Loa Observatory on July 12, 2021, and will continue the calibration until the end of August.
Global Monitoring Laboratory and NASA team up in the DCOTSS (Dynamics and Chemistry of the Summer Stratosphere) project to study the convective impact of the North American Monsoon Anticyclone on stratospheric composition and ozone depletion.
The Global Monitoring Laboratory is currently redesigning the 41-year-old, balloon-borne frost point hygrometer that measures vertical profiles of water vapor from the surface to about 28 km above sea level in the middle stratosphere.
The Global Monitoring Laboratory finished homogenizing multiple NOAA satellite and in-situ ozone records up until 2020, which will be used for trend analysis to understand the current status of ozone depletion in the stratosphere.
During COVID-19 shutdowns last year, ozone levels in the lower atmosphere fell by seven percent across much of the Northern Hemisphere, according to a new study.
Persistent cold temperatures and strong circumpolar winds supported the formation of a large and deep Antarctic ozone hole that will persist into November, NOAA and NASA scientists reported today.
In April 2020, the Global Monitoring Laboratory’s measurement record of upper atmospheric water vapor over Boulder, Colorado, surpassed 40 years in length.
Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October, resulting in the smallest ozone hole observed since 1982.
The ozone hole that forms in the upper atmosphere over Antarctica each September was slightly above average size in 2018, NOAA and NASA scientists reported today.
