Science Features : TES
Entrainment rate (λ) in convective parameterizations is one of the most sensitive, yet uncertain, parameters affecting climate sensitivity, clouds, precipitation, and trace gas distributions.
In "Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space”, Aura data were presented as examples of satellite observations used as a global monitoring system for air quality & health and stratospheric ozone.
Peroxyacyl nitrate (PAN) is a critical atmospheric reservoir for nitrogen oxide radicals, and plays a lead role in their redistribution in the troposphere.
In the troposphere, ozone is both a major pollutant and a strong greenhouse gas. Although spaceborne and ground-based observations largely agree on the overall tropospheric ozone loading, estimates of decadal-scale trends vary significantly between datasets.
NASA Ozone Study May Benefit Air Standards (Science Daily article)
A new NASA-led study uses TES data to find that when it comes to combating global warming caused by emissions of ozone-forming chemicals, location matters.
The Global Carbon Cycle04.2011
- TES measurements provide constraints on carbon dioxide (CO2
) emission and uptake and methane (CH4
TES Water Vapor Isotopes04.2011
- Stable isotopes from TES is used to constrain convective parameterization in a climate model.
Ammonia from TES
- TES captures the variability of ammonia over the Earth's surface.
TES Hunts the Trail of Earth's Water
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.
TES Carbon Monoxide
High values of CO near biomass burning regions and NH cities. CO in the upper trop is lofted by convection and fires.
