ESRL's Global Monitoring Division conducts sustained observations and
research related to global distributions, trends, sources and sinks of
atmospheric constituents that are capable of forcing change in the climate
of the Earth. This research will advance climate projections and provide
scientific policy-relevant, decision support information to enhance
society's ability to plan and respond.
ESRL's Global Monitoring Division conducts research on the depletion
of the global stratospheric ozone layer and Antarctic ozone hole through
global surface-based monitoring of total-column ozone, ultraviolet radiation,
and ozone-depleting gases, including those regulated by the Montreal Protocol.
Continued surveillance is necessary in order to verify the expected
recovery of the ozone layer.
ESRL's Global Monitoring Division monitors levels of air quality
elements such as tropospheric ozone, carbon monoxide and aerosol
particles in non-source regions which may be affected by long range
transport from distant sources of industrial pollution. This large-scale
transport affects baseline air quality which must be monitored
in order to determine the importance of regional sources that may impact
the environment and public health.
NOAA's Earth System Research Laboratory (ESRL), Global Monitoring Division, is pleased to announce the 44th Global Monitoring Annual Conference to be held Tuesday and Wednesday, May 17th and 18th, 2016, in Boulder, Colorado.
In the Northern Hemisphere, the spring equinox promises warmer days and green plants. But for researchers at NOAA's South Pole Atmospheric Baseline Observatory, Sunday March 20 marks the start of the austral autumn, the last time they see the sun for six months.
The annual growth rate of atmospheric carbon dioxide measured at NOAA’s Mauna Loa Observatory in Hawaii jumped by 3.05 parts per million during 2015, the largest year-to-year increase in 56 years of research.
Carbon tetrachloride (CCl4) was once commonly used as a cleaning agent and remains an important compound in the chemical industry. As a result, production across the globe has been banned for uses that result in CCl4 escaping to the atmosphere. A new study, led by CIRES scientist Lei Hu and NOAA scientist Stephen Montzka of NOAA ESRL's Global Monitoring Division, reports that release rates are still 30 to 100 times higher than amounts reported to emission inventories.
NOAA/ESRL's Global Monitoring Division has introduced a 'Trends in Atmospheric Methane' web page. Similar to the existing 'Trends in Carbon Dioxide' web page, it displays graphs and data for the most recent globally averaged CH4 data.
Ann Thorne of the Global Monitoring Division received the NOAA Research Employee of the Year Award "For exceptional service to NOAA's Global Monitoring Division and Earth System Research Laboratory, and an unsurpassed spirit and dedication to the NOAA Boulder Student Program."
NOAA’s measurements of ozone at South Pole registered a record low for the month of October. This year, the average amount of ozone measured by a Dobson instrument at South Pole in the second half of October was 114 Dobson Units (DU), or 60 percent below the pre-ozone hole conditions.
