Dr. Jennifer Kaiser

Jennifer Kaiser is the Greene Early Career Professor at Georgia Institute of Technology. Her research combines suborbital and satellite-based observations with chemistry-transport modeling to probe the emissions and impact of a wide range of sectors. She is a steering committee member of the IGAC (International Global Atmospheric Chemistry) AMIGO (Analysis of eMIssions usinG Observations) group, which aims to organize the international scientific community on the topic of observation-based emissions constraints.

HAQAST Project: Using Earth Observations to Investigate Diurnal Bias in Sectorized Emissions, and its Impact on Simulating Exposure of Air Pollution and Implications for Control Strategy Design and Public Health Assessment

Jen’s team will use Earth observations to investigate biases in emissions and provide estimates of how time sensitive sector sources are for improved decision-making in air quality and environmental health management. This project will use NASA’s TEMPO instrument for hourly satellite data during the day (as well as other instruments including TROPOMI, MODIS, and MAIA when available), ground-based observation networks (including SLAMS, PAMS, NCORE, CSN, IMPROVE and ASCENT), and modeling. 

Project goals / deliverables:

1. Quantify diurnal biases in the sectorized emissions of US EPA’s National Emissions Inventory (NEI) using Earth observations
2. Study the impact of diurnal bias in the sectorized emission on the accuracy of predictions of air quality and population-level exposures, and identify implications for control strategy design and health assessments
3. Develop fields of time-split sectorized source contributions and exposures to inform end-users
