NASA satellites continue to capture remarkable new images of the wildfires raging in Southern California. Aura's OMI images show the smoke aerosol layer generated by the fires in Southern California as it drifts over the Pacific Ocean.
Recent observations by the HIRDLS and CALIPSO experiments provide more detailed observations of the subvisible cirrus. This information will help describe the physics of cirrus formation, and possible future changes in stratospheric and upper tropospheric water vapor.
The HIRDLS instrument aboard the Aura satellite is measuring temperature profiles of the atmosphere, revealing small-scale atmospheric buoyancy waves (also known as "gravity waves") in fine detail.
Prolonged low temperatures in September 2006 increased by the longevity of 'active chlorine', leading to a record area and depth of the ozone hole.
For the first time, NASA scientists have used a shrewd spaceborne detective to track the origin and movement of water vapor throughout Earth's atmosphere.
Proposed orbit change for the Aura spacecraft
10.29.2007 - The Aura spacecraft currently flies about 15.22 minutes behind Aqua in the A-Train. The Aura Project is proposing to move Aura spacecraft closer to Aqua. Aura would follow Aqua by about 8 minutes along the same track after the move.
NASA Keeps Eye On Ozone Layer Amid The Montreal Protocol's Success
09.13.2007 - NASA scientists will join researchers from around the world to celebrate the 20th anniversary of the Montreal Protocol, an international treaty designed to reduce the hole in Earth's protective ozone layer.
A NASA Space Sleuth Hunts the Trail of Earth's Water
01.31.2007 - For the first time, NASA scientists have used a shrewd spaceborne detective to track the origin and movement of water vapor throughout Earth's atmosphere. This perspective is vital to improve the understanding of Earth's water cycle and its role in weather and climate.
Sources of the World's Tiny Pollutants
01.30.2007 - Pinpointing pollutant sources is an important part of the ongoing battle to improve air quality and to understand its impact on climate. Scientists using NASA data recently tracked the path and distribution of aerosols -- tiny particles suspended in the air -- to link their region of origin and source type with their tendencies to warm or cool the atmosphere.
