Dr. Joanna Joiner Named Recipient of 2020 William Nordberg Memorial Award for Earth Science

06/24/2020
We are thrilled to announce the selection of Dr. Joanna Joiner as the 2020 William Nordberg Memorial Award for Earth Science winner.

Dr. Joiner is being recognized for exceptional scientific breakthroughs and leadership in the remote sensing of clouds, trace gases, and photosynthesis.

Dr. Joiner serves as Deputy Project Scientist for the NASA EOS Aura satellite and is the lead for the U.S. OMI Science Team, managing the core team that provides critical support for OMI science team members and the wider user community. Together with her international co-Leads, Dr. Joiner accepted the 2018 USGS Pecora Award on behalf of the entire OMI Science Team.

Of particular note is Dr. Joiner’s innovative application of inelastic rotational Raman scattering (the Ring Effect) in UV remote sensing to derive trace-gas vertical profiles and to measure the Solar Induced Fluorescence (SIF) of chlorophyll as a means of estimating gross primary production (GPP) over land surfaces. These contributions, and insights that have produced additional improvements to SO2 retrieval, represent major advances in the field of UV remote sensing, having wide practical implications.

Dr. Joiner will be presented with the William Nordberg Memorial Award during a future Scientific Colloquium that will be scheduled once we are all back on Center.

Earth Matters Blog: Nimbus-4–A Satellite Pioneer For Ozone Research

04/09/2020
When NASA launched the Nimbus-4 satellite 50 years ago, nobody knew the ozone layer over Antarctica was thinning. And nobody knew that chlorofluorocarbons (CFCs)—long-lived chemicals that had been used in refrigerators and aerosol sprays since the 1930s—were responsible.

Earth Day Countdown Blog: T-17–Chemistry in the Atmosphere

04/05/2020
Air pollution can appear as a gray or orange haze enveloping a city. What the naked eye can’t see are the hundreds of chemical reactions taking place to produce that pollution. NASA science can reveal a more complete picture of atmospheric chemistry.

Version 2 Aura Ozone Monitoring Instrument (OMI) SO2 Product Release

04/01/2020
