Levels of "background ozone" -- ozone pollution present in a region but not originating from local, human-produced sources -- are high enough in Northern California and Nevada that they leave little room for local ozone production under proposed stricter U.S. ground-level ozone standards, finds a new NASA-led study. more >>
Rapid population growth and industrialization have driven substantial increases in Asian ozone precursor emissions over the past decade. Global efforts may be required to address regional air quality and climate change. more >>
Continental precipitation not routed to the oceans as runoff returns to the atmosphere as evapotranspiration. Partitioning this evapotranspiration flux into interception, transpiration, soil evaporation, and surface water evaporation is difficult using traditional hydrological methods, yet critical for understanding the water cycle and linked ecological processes. more >>
TES profiles for the vertical distribution of carbon monoxide emitted by the many wildfires burning in Northern California in late June/early July 2008, illustrate the fires' impact on air quality. more >>
TES team members attended the ASSFTS (Atmospheric Science from Space using Fourier Transform Spectrometers) meeting in November 2007 in Toulouse, France, and joined in discussions of the new results from spaceborne FTS instruments.
NASA's newest detective in the mysteries of atmospheric water vapor tracks observations of heavy and light water vapor to retrace the "history" of water over oceans and continents, from ice and liquid to vapor and back again. more >>
The California Institute of Technology (Caltech) Postdoctoral Scholars Program at the Jet Propulsion Laboratory (JPL) invites applicants for two postdoctoral research positions with the Tropospheric Emission Spectrometer (TES) group. more >>
A NASA and university study of ozone and carbon monoxide pollution in Earth's atmosphere is providing unique insights into the sources of these pollutants and how they are transported around the world. more >>
By investigating the relationship between ozone and carbon monoxide, science investigators using TES data are able to detect pollution drift patterns, and may also be able to reveal ozone sources. more >>
The TES science team meeting will be held at the University of Phoenix in Pasadena on Nov 13 & 14, 2006. We will discuss instrument status, validation, science results, science planning, and algorithm changes.
Aura was transported from NGST to Vandenberg Air Force Base, California to begin launch preparations. The spacecraft will undergo final tests and integration with a Boeing Delta II rocket for a scheduled launch in June.
