Dirty Finger Print

“Then God said, ‘Let us make man in our image, after our
likeness; and let them have dominion over the fish of the sea, and over the birds
of the air, and over the cattle, and over all the earth, and over every creeping
thing that creeps upon the earth.'” – Genesis 1:26

“And the Lord said, ‘Who then is the faithful and wise steward, whom his master
will set over his household, to give them their portion of food at the proper time?'”
– Luke 12:42

Satellite produces global air pollution map

Energy and Environment Based on 18 months of Envisat observations, this high-resolution global atmospheric map of nitrogen dioxide pollution makes clear just how human activities impact air quality. ESA’s ten-instrument Envisat, the world’s largest satellite for environmental monitoring, was launched in February 2002. Its onboard Scanning Imaging Absorption Spectrometer for Atmospheric Chartography (SCIAMACHY) instrument records the spectrum of sunlight shining through the atmosphere. These results are then finely sifted to find spectral absorption ‘fingerprints’ of trace gases in the air.
