Nitrogen dioxide (NO2) is found in the troposphere (the layer of the atmosphere closest to the surface) and in the stratosphere (the layer of the atmosphere that protects us from harmful UV radiation). When we measure NO2 from space-based instruments, we measure the combined NO2 in both layers. Separating the stratospheric and tropospheric content is critical to the application and interpretation of these satellite observations. In our latest article that has just been published in Atmospheric Measurement Techniques, we show how this will be possible for a new geostationary satellite instrument called TEMP (anticipated to launch sometime around 2021).

Research on Tap: Understanding and Forecasting Change in Our Natural World
This afternoon, Jeff is participating in a "Research on Tap" event at BU, focused on gathering together investigators across many disciplines who are interested in exploring how to forecast changes in the natural world. Jeff will be discussing links between variability in the natural environment and global air quality. The event was hosted by Gloria Waters (Vice President and Associate Provost for Research at BU) and Prof. Mike Dietze (Associate Professor in the Department of Earth & Environment at BU).
GEMS Meeting in Seoul
This week, Jeff is in Seoul, Korea, to attend the 9th Geostationary Environmental Monitoring Spectrometer (GEMS) Science Team Meeting. GEMS is a geostationary satellite instrument that will be dedicated to monitoring tropospheric pollution over Asia. Jeff will be presenting his work on an algorithm to separate the signal of NO2 in the stratosphere from the total atmospheric column, in order to determine the amount of NO2 in the troposphere alone.
Welcome to Marissa
Welcome to Marissa Lee, who is joining the Geddes group as a work-study student this year. Marissa is an undergraduate student at Boston University, majoring in Earth and Environmental Science with a minor is Remote Sensing and GIS.
Is the U.S. the cleanest country on the planet?
Last week, Jeff was quoted in an article from politifact.com discussing the truth in a statement from President Trump about how clean the air and water is in the United States. Thanks to Manuela Tobias for reporting.
Welcome to Taylor
Welcome to Taylor Adams, who is joining the Geddes group as a Ph.D. student this fall. Taylor earned a BA in Chemical and Biomolecular Engineering from the University of Tennessee Knoxville. In addition to research with the Geddes group, Taylor will be in the inaugural cohort of the BU URBAN trainee program.
Boston Globe Interview
On Monday July 9, the Boston Globe featured an interview with Jeff about his research projects at Boston University. Jeff talks about the importance of understanding the interactions between emissions from natural and human systems, and about sampling air pollution in the Boston area. Thanks to Emily Williams for reporting. To read the full interview, click here.

TEMPO Meeting in Boulder
Jeff travels to Boulder, CO this week for the annual TEMPO Science Team meeting. TEMPO is a geostationary satellite instrument that will be dedicated to monitoring tropospheric pollution over North America. Jeff is working on an algorithm to separate the signal of NO2 in the stratosphere from the total atmospheric column, in order to determine the amount of NO2 in the troposphere alone.
Canadian Chemistry Conference in Edmonton
This week, Jeff is in Edmonton to present his research at the 2018 Canadian Society of Chemistry meeting (http://www.csc2018.ca/). His talk is entitled "Investigating Rapid Contemporary Changes in Biosphere-Atmosphere-Chemistry Interactions with a Chemical Transport Model".
