Farewell to a pioneering pollution sensor

On Jan. 31, NASA ended the Tropospheric Emission Spectrometer's (TES) almost 14-year career of discovery. Launched in 2004 on NASA's Aura spacecraft, TES was the first instrument designed to monitor ozone in the lowest layers ...

Team measures lightning-produced ozone with Lidar

Scientists at The University of Alabama in Huntsville (UAH) have used UAH's Rocket-city Ozone (O3) Quality Evaluation in the Troposphere (RO3 QET) Lidar to measure ozone that was chemically produced by summertime lightning ...

NASA examines global impacts of the 2015 El Nino

People the world over are feeling, or soon will feel, the effects of the strongest El Niño event since 1997-98, currently unfolding in the eastern equatorial Pacific Ocean. New satellite observations are beginning to show ...

Natural ozone changes suggest good news for future

(Phys.org) —New NASA research on natural ozone cycles suggests ozone levels in the lowest part of Earth's atmosphere probably won't be affected much by projected future strengthening of the circulating winds that transport ...

Europe clears the air

Satellite measurements show that nitrogen dioxide in the lower atmosphere over parts of Europe and the US has fallen over the past decade. More than 15 years of atmospheric observations have revealed trends in air quality.

Superconducting submillimeter-wave limb-emission sounder (SMILES)

The Superconducting Submillimeter-Wave Limb-Emission Sounder (SMILES) is the first onboard mechanically cooled superconducting mixer and high-resolution system for measuring atmospheric minor constituents related to stratospheric ...
