Science Features : 2005

Aura Science Result Image NASA Satellite Eyes Atmosphere to Improve Pollution and Climate Forecasting
Thanks to the latest sophisticated, satellite-based instruments, local and regional air pollution and their sources can now be observed closely from space.
Aura Science Result Image Eruption of Anatahan
This image of the volcanic eruptions from Anatahan (Mariana Islands) shows sulfur dioxide concentrations in the atmosphere on April 7, 2005, over 30 hours after the eruption.
Aura Science Result Image OMI Measurement of Nitrogen Dioxide
This image from Aura's OMI instrument shows the total column amount of nitrogen dioxide, a precursor to the formation of tropospheric ozone.
Aura Science Result Image Destruction of Arctic Ozone this Winter
An unprecedended suite of simultaneous measurements by MLS allows more accurate quantification of ozone destruction in the 2004-2005 Arctic winter.
Aura Science Result Image MLS detects SO2 and HCI injected into the stratosphere by the 27 January 2005 New Guinea Manam volcano.
These images show MLS detection of enhanced SO2 and HCI in the lower stratosphere over New Guinea on January 28, following eruption of Manam volcano on January 27.
Aura Science Result Image Sulfur Dioxide Plume From Manam Volcano
When the Manam volcano erupted explosively in the middle of the night on January 27, 2005, it sent a cloud of ash and sulfur dioxide over New Guinea.
