Health and Air Quality Articles

Photo of industrial smoke stacks.Every year, around 7 million deaths occur due to exposure from air pollution and 9 out of 10 people worldwide breathe polluted air, according to the World Health Organization. Scientists, health officials, and air quality managers around the globe are conducting research into this silent but deadly killer. With the information acquired from both ground-based and satellite- based data, decision makers are able to monitor and respond to events. These articles, many from the Sensing Our Planet series, highlight some of these efforts.

Aerosols | Air Quality | Atmospheric Chemistry

Aerosols
Aerosols are particulate matter, like dust, ash and smoke, from both natural or anthropogenic, or human-caused, sources. They are found in the atmosphere around the globe.

The power of particles
Can smoke spark severe tornadoes?

Volatile trees
Forests fill the air with more than just a fresh scent.

Himalayas heat pump
Polluted air over Asia is changing patterns in remote mountain ranges.

Smoke over Athens
The effects of forest fires show up in a multi-satellite view of pollution.

Aerosols over Australia
Researchers explore the links between atmospheric aerosols, climate change, and ultraviolet rays.

Following the World Trade Center plume
Remote sensing helps track the drift of harmful pollutants following the World Trade Center collapse.

Nature’s contribution
Researchers investigate how much wildfires contribute to pollution, and how far this pollution can travel.

When the Dust Settles
Each year, several hundred million tons of African dust are transported westward over the Atlantic to the Caribbean, Central America, and South America.

Volcanoes and Climate Change
Large-scale volcanic activity may last only a few days, but the massive outpouring of gases and ash can influence climate patterns for years.

Effects of Emissions on Climate Change
Qualitative improvement of the IPCC scenarios.

A Burning Question
Atmospheric aerosols’ effect on surface temperatures.

Air Quality
Air quality is impacted by elements in the atmosphere, such as nitrogen dioxide, carbon monoxide, and tropospheric ozone. These elements can react with others, forming particulate matter and ozone, producing haze and even acid rain.

Out of Africa
Researchers revise the story behind Puerto Rico’s 2015 drought.

Under CATS eyes
Tracking a volcanic plume reaches new heights, faster.

A rising problem
Tackling Denver's ozone requires looking high and low.

Carbon control
Radiocarbon and satellite data hint at the future of California emissions.

Crisis in the Crescent
Drought turns the Fertile Crescent into a dust bowl.

Crazy bad air
Open sharing of pollution data helps Chinese netizens brave the politics of murky air.

A black cloud over Cairo
The source of a yearly scourge is revealed.

Heart disease is in the air
The air you breathe could be harming your heart.

Probing the Arctic atmosphere
One of the least industrial areas of Earth is a crossroads for pollution.

Regional pollution goes local
Distant pollution sources worsen local air quality in southeastern Texas.

Pollution trials for the Beijing Olympics
Satellites reveal that traffic restrictions successfully reduced atmospheric nitric oxide by 40 percent.

On the trail of global pollution drift
Scientists use NASA's Tropospheric Emission Spectrometer (TES) to study drifting pollution and its sources.

Critical Chemistry
Mapping out global distribution and concentrations of reactive nitrogen species — a chemical precursor to ozone.

Atmospheric Chemistry
There are many elements that make up our atmosphere, like nitrogen, oxygen, and carbon. How they react with other elements influence atmospheric chemistry.

In the Arctic darkness
Beneath a frozen surface, stirrings.

Mercury raining
Today's forecast calls for atmospheric explosions and mercury rain.

A new pole hole
In winter 2011, an ozone hole appeared over the Arctic for the first time.

The UARS Cornucopia: A Legacy of Research
Nine years after its initial deployment, the Upper Atmosphere Research Satellite (UARS) is more than just an antiquated piece of metal floating around in space.

Carbon Conundrum
Research results highlight the role of new data sets in understanding global change, Schimel said, as well as the usefulness of computer models that connect the atmosphere and the biosphere.

Outer Limits
Upper atmosphere's role in Earth's climate remains to be determined.

UARS: A Model Dataset
The UARS satellite has revolutionized our view of the mesosphere.
