Sep 2022: New paper on Hurricane Ida's impact on air pollution
Tabitha Lee used TROPOMI satellite to detect tropospheric NO2 changes due to the landfall of Hurricane Ida on Louisiana coast on Aug 29, 2021. The paper was published on Environmental Science & Technology Letters. It is the first study using satellites to quantify the disruption of short-lived extreme weather events such as hurricanes on the chemical composition of the atmosphere, and the impact was shown to be large. See this news piece on the paper.
Sep 2021: Tabitha awarded FINESST grant from NASA
Ph.D. student Tabitha Lee was awarded Future Investigators in NASA Earth and Space Science and Technology (FINESST) research grant for 3 years. The grant will support her thesis research on developing new approaches of using TROPOMI data to better identify unreported emission sources of NOx. Congrats Tabitha! See this news piece on her grant.

She is looking forward to her LaRC visit this summer! See this news piece on her fellowship and her first publication.
Dec 2019: Group made multiple presentations at AGU in San Francisco
Six members from the group went to the 2019 AGU Fall Meeting in San Francisco during 9-13 Dec 2019. Our presentations are listed below. We all had a fun and fruitful week at AGU!
Yuxuan Wang (invited talk): Impact of drought on air quality
Wei Li (talk): Transport effects on ozone variability in San Antonio and Houston
Sally Wang (poster): Predicting wildfire burned area inSouth Central USusing integrated machine learning techniques
Elizabeth Klovenski (poster): Understanding Drought Perturbations on Biosphere-Atmosphere-Chemistry Relationship with GISS ModelE + MEGAN simulations
Claudia Bernier (poster): Clustering Surface Ozone Diurnal Cycles to Understand the Impact of Circulation Patterns in Houston, TX
Nan Lin (poster): Comparative study of GEOS-Chem and WRF-GC in the United States
Jun 2019: Group awarded new grants from NASA and NOAA
Yuxuan Wang received two new grants to investigate atmospheric chemistry impacts of droughts. The first grant is from NASA Atmospheric Composition Modeling and Analysis Program (ACMAP) and the objective is to improve our understanding of how biogenic volatile organic compounds (BVOC) emissions respond to drought stress using a multitude of observations (aircraft, surface, and satellite) and modeling (GEOS-Chem). We will collaborate with Drs. Alex Guenther and Saewung Kim at UCI on the NASA project [Read more].
The second grant is from NOAA Atmospheric Chemistry Carbon Cycle and Climate (AC4) Program. With the NOAA grant, we will conduct a holistic and long-term analysis of atmospheric composition changes during droughts in the continental U.S. and with such observational constraints, we will develop process-based metrics to evaluate earth system models in simulating the coupling of drought and atmospheric composition. Our collaborators include Dr. Jun Wang from U. Iowa and GFDL.
4/8/2019: Sally defended her Ph.D. thesis!
Sally successfully defended her Ph.D. thesis entitled "Impact of Biomass Burning on Regional Air Quality and Weather Patterns in Texas" on April 8, 2019. This is an important milestone not only for her personally but also for the group as she is the first Ph.D. graduated from our group at UH. Here is a memorable photo when Sally received a surprise party by the sweet undergraduate students in the Atmospheric Biogeochemistry lab session she's been teaching this semester.
3/1/2019: Group awarded a new grant from TCEQ
We are excited to be awarded a new grant from TCEQ to conduct synthesis analysis of mesoscale and synoptic-scale circulation patterns on ozone transport and formation in Houston and San Antonio. This project builds upon our prior work on background ozone and large-scale meteorological drivers of ozone variability in the region. It will allow us to study mesoscale circulation such as the sea breeze and assemble the mesoscale and synoptic-scale pieces into a coherent picture of the weather patterns conducive to high ozone in the Houston and San Antonio areas. Stay tuned to our progress in the Publication and Presentation page!
10/31/2018: Elizabeth wins NASA Fellowship
Ph.D. student Elizabeth Klovenski was awarded a NASA ASTAR Fellowship to study drought effects on BVOC-chemistry-climate interactions. She will primarily use the GISS ModelE, a leading earth system model. The Fellowship will support her for 3 years, including her visits and training at NASA Goddard. Congratulations! [Read more]
