Introduction FRAPPÉ - the Front Range Air
Quality Photochemistry Experiment - aims to characterize and
understand summertime air quality in the Northern Front Range
Metropolitan Area. FRAPPÉ is a collaborative effort between the
Colorado Department of Public Health and the Environment, the
University of Colorado and Colorado State University, UC Berkeley,
and other university collaborators, local projects and agencies
including local school districts, NASA, NOAA, and NCAR. This
mission will be closely coordinated with the NASA DISCOVER-AQ
project, which has agreed to conduct their final aircraft
deployment in the Colorado Front Range.

Aqua Satellite Swath
Our atmosphere supports and protects life on Earth. NASA
satellites observe the impact that 7 billion humans are having on

Blue Marble Nightlights
From space Earth at night reveals concentrations of human activity
- and this activity is correlated to air pollutants.

Blue Marble (no
clouds) with Pollution PIP's
NASA satellites observe the impact of 7 billion humans.
-Slash-and-burn deforestation over Mexico
-Los Angeles smog
-pollution over China
-haze over Bangladesh from fire and burning fossil fuels
-West Africa fires and smoke from agricultural clearing
-smog over France
-smog over U.S. East Coast
Natural air pollution caused by: volcanoes, sand storms,
fires started by lightening
Nitrogen Dioxide over Night Lights - OMI
Nitrogen Dioxide is released into the air by burning coal,
gasoline, and other fossil fuels. It is unhealthy to breathe and
reacts with other gases to produce ozone, which is also unhealthy
-Globally, greatest NO2 emissions are from industrial, urban
centers (coal, gas-fired power plants, vehicles), forest
-High levels of NO2 contribute to:
1) haze that reduces visibility
2) irritation of the eyes, nose, throat, and lungs
3) acid rain
-Strong seasonal pattern corresponds to more heating and longer
pollutant lifetime in winter
-Emissions controls have successfully decreased NO2 in some areas,
but new development corresponds to increasing NO2

Earth at Night: 1992, 2002,
Earth is never dark everywhere, except briefly during a rare total
solar eclipse, but here the whole Earth is shown at night over 20
years: 1992, 2002, 2012. Notice how many more lights turned on over
two decades. More people. More cities. More lights. More energy
What do most power plants use to generate electricity?
Humans are having a noticeable effect on our atmosphere. More
people and industry impact air quality, especially in places like
China and India with growing populations and development.

Aerosols from GEOS-5 and the GOCART
-sea salt from the oceans (blue)
-dust off the deserts (red)
-soot/black carbon aerosols (green) can occur naturally (e.g.
forest fires caused by lightening) or from human activity (e.g.
agricultural fires, fossil fuel combustion).
-sulfate aerosols (white) comes from the combustion of fossil
fuels and the eruption of volcanoes, most commonly found downstream
of large industrial areas.
The good news is that there have been improvements in air quality
over the United States and Europe thanks to tougher regulations and
using cleaner energy sources.
Monitoring our atmosphere with satellites and working together
with other countries, we can identify pollution sources to clean up
our air. Our atmosphere is essential for life on Earth.
