Version 2 Sulfur Dioxide (SO2) Earth System Data Record (ESDR) Released

10.30.2020
The GES DISC (610.2) and the NASA Goddard Atmospheric Chemistry and Dynamics Laboratory released a new Version 2 of Sulfur Dioxide (SO2) Earth System Data Record (ESDR). The data are based on Backscatter Ultraviolet (BUV) measurements from the Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper (NM), flown on the NASA/NOAA Suomi National Polar-orbiting Partnership (S-NPP) satellite.

U.S. Patent Awarded for Detecting Hydroxyl

07.10.2020
Steven A. Bailey (550) and Thomas F. Hanisco (614) were awarded a patent for their method to detect OH (hydroxyl radicals) in an atmosphere. U.S. Patent Number: 10697890 is entitled “Apparatus and Method of Hydroxyl Detection” and was awarded on June 30, 2020. The patent came from their research on hydroxyl radiometers.

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.

Overview

The Atmospheric Chemistry and Dynamics Laboratory studies the ozone layer, a responsibility the Clean Air Act assigns to NASA. In addition, there is increasing concern about the global aspects of tropospheric pollution, and the coupling between chemical composition and climate.

One of the Laboratory's principal missions is to understand the behavior of stratospheric ozone and trace gases that influence ozone. Ozone and trace gases such as methane, nitrous oxide, and the chlorofluorocarbons profoundly influence Earth's habitability.

The Laboratory also studies the processes that control the composition of Earth's troposphere, the impact of human activity on global atmospheric pollution, and the impact of climate change on future concentrations of stratospheric ozone and tropospheric gases.
