Atmospheric Tomography Mission (ATom)

The Atmospheric Tomography Mission (ATom) is a NASA-funded multi-agency effort using the NASA DC-8 research aircraft to systematically sample trace gases and aerosols from sea level to the stratosphere on 10 pole-to-pole flights covering the Atlantic and Pacific oceans over the next 3 years. ATom will study the impact of human-produced air pollution on greenhouse gases and on chemically reactive gases in the atmosphere with a focus on ozone, methane, and black carbon, as well as atmospheric particulate matter.

As Alaska warms, methane emissions appear stable

Analysis of nearly three decades of air samples from Alaska’s North Slope shows little change in long-term methane emissions despite significant Arctic warming over that time period, according to new research published in Geophysical Research Letters.

MLO Science Fair Awards

Every year MLO contributes to the local Science Fair event. This year Samantha Yamamoto & Maile Birlhante won the junior research award with their project 'Light Dispersing'. Kendra Puleo won the second award with 'Ocean acidification effect on the food chain.' Kylan K. Sakata won the senior division award with 'Verifying special relativity over time dilation through moon decay at variable altitudes' and Moana Lily Pinner won the second award with 'Investigating the SPF, anti-oxidant and anti cancer potential of turmeric and ginger.'

South Pole is last place on Earth to pass global warming milestone

The Earth passed another unfortunate milestone May 23 when carbon dioxide surpassed 400 parts per million (ppm) at the South Pole for the first time in 4 million years.

Arctic set for record-breaking melt this summer

The record heat baking Alaska is poised to smash a host of climate records in 2016, including the earliest snowmelt date at NOAA’s Barrow Observatory, the northernmost point in the nation.

Warming due to carbon dioxide jumped by half in 25 years

Human activity has increased the direct warming effect of carbon dioxide (CO2) in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Annual Greenhouse Gas Index .

Last light: Sunset at the South Pole

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.

Record annual increase of carbon dioxide observed at Mauna Loa for 2015

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.
When Less Is More

When Less Is More

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.

2015 Sets a Record Low for Antarctic Ozone Hole in October

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.

Scientists find Southern Ocean removing CO2 from the atmosphere more efficiently

Since 2002, the Southern Ocean has been removing more of the greenhouse gas carbon dioxide (CO2) from the atmosphere, according to two new studies. These studies make use of millions of ship-based observations and a variety of data analysis techniques to conclude that the Southern Ocean has increasingly taken up more CO2 during the last 13 years.
