Nationwide study measures short-term spike in particulate matter due to Independence Day fireworks

From our nation’s founding, the Fourth of July has been synonymous with fireworks. While many grew up learning that fireworks can be dangerous to the eyes and hands if not handled properly, fireworks also produce air pollutants, including particulate matter, that are linked to short-term or long-term health effects.

NOAA has authored a new study appearing in the journal Atmospheric Environment that quantifies the surge in fine particulate matter – particles that are two and one half microns in diameter (PM2.5) – on July 4, using observations from the 315 U.S. air quality monitoring sites that operated from 1999 to 2013. The new study is the first nationwide quantitative analysis of the effects.

New study shows Arctic Ocean rapidly becoming more corrosive to marine species

New research by NOAA, University of Alaska, and Woods Hole Oceanographic Institution in the journal Oceanography shows that surface waters of the Chukchi and Beaufort seas could reach levels of acidity that threaten the ability of animals to build and maintain their shells by 2030, with the Bering Sea reaching this level of acidity by 2044.

Stricter limits for ozone pollution would boost need for science, measurements

Stricter limits for ozone pollution would boost need for science, measurements

A tougher federal standard for ozone pollution, under consideration to improve public health, would ramp up the importance of scientific measurements and models, according to a new commentary published in the June 5 edition of Science by researchers at NOAA and its cooperative institute at the University of Colorado Boulder.

The commentary, led by Owen Cooper of the Cooperative Institute for Research in Environmental Sciences and NOAA’s Earth System Research Laboratory, looks at how a new, stricter ozone standard would pose challenges for air quality managers at state and local levels. Last November, the Environmental Protection Agency proposed lowering the primary ozone standard from 75 parts per billion (ppb) to 70 or 65 ppb, based on ozone’s known effects on children, the elderly, and people who have lung diseases such as asthma. A decision by the EPA administrator is expected in October 2015.

NOAA represents US in Atlantic Ocean Research Alliance mapping survey

NOAA represents US in Atlantic Ocean Research Alliance mapping survey

Today, a multi-national team of Canadian, European and American ocean mapping experts launch the first trans-Atlantic mapping survey under the Atlantic Ocean Research Alliance. The expedition will map from St. John, Newfoundland to Galway, Ireland. 

The survey is one of the first projects to be launched by the Alliance, formed in May 2013 following the Galway Statement on Atlantic Ocean Cooperation, whose goals are to join resources of its three signatories to better understand the North Atlantic Ocean and to promote the sustainable management of its resources.

NOAA researchers will use 2015 season to improve hurricane track and intensity forecasts

This hurricane season, NOAA’s Office of Oceanic and Atmospheric Research will work with NOAA’s National Weather Service to upgrade weather forecast models and conduct research with unmanned air and water craft to improve forecasts of hurricane track and intensity.

NOAA scientists tackle mystery of nighttime thunderstorms

This summer, more than 20 NOAA scientists will stay up late to learn why some thunderstorms form and grow at night, without the energy from the sun's heat. They will be participating in the Plains Elevated Convection At Night (PECAN), a large, intensive field campaign to collect data before and during nighttime thunderstorms in the western Great Plains from June 1 to July 15. 

Research needed to resolve connections between Arctic warming and severe weather

Research needed to resolve connections between Arctic warming and severe weather

It is too soon to know if recent extreme cold weather such as the last two East Coast winters are linked to Arctic climate warming, according to new research published in the Journal of Climate by James Overland of NOAA, and other authors from North America, Asia and Europe.

NOAA Scientists Provide Expertise for the $2 Million Wendy Schmidt Ocean Health XPRIZE

We caught up recently with Remy Okazaki at NOAA’s Pacific Marine Environmental Laboratory in Seattle.  Remy is a chemist with the University of Washington Joint Institute for the Study of the Atmosphere and Ocean (JISAO) working with PMEL’s carbon team on the $2 million Wendy Schmidt Ocean Health XPRIZE, a global competition to advance ocean pH sensing technology to better understand, measure and address ocean acidification. On May 14, XPRIZE will begin the final phase of testing in deep water off the northern coast of Oahu, Hawaii, aboard the R/V Kilo Moana research vessel.
New research will help forecast bad ozone days over the western U.S.

New research will help forecast bad ozone days over the western U.S.

New research published in Nature Communications led by Meiyun Lin of NOAA’s Geophysical Fluid Dynamics Laboratory and NOAA’s cooperative institute at Princeton University, reveals a strong connection between high ozone days in the western U.S. during late spring and La Niña, an ocean-atmosphere phenomena that affects global weather patterns.
Greenhouse gas benchmark reached

Greenhouse gas benchmark reached

For the first time since we began tracking carbon dioxide in the global atmosphere, the monthly global average concentration of this greenhouse gas surpassed 400 parts per million in March 2015,  according to NOAA’s latest results.
