Starting 3rd September

Session 2: Modelling Street Level PM Dispersal

Tue 8th Oct, 2024; Wed 9th Oct, 2024 | Dr. Konstantin Kuznetsov

Urban air quality monitoring is often restricted by the resolution of satellite imagery, typically between 100 and 1000 meters. A new approach combines satellite data with Computational Fluid Dynamics (CFD) modeling to retrieve road emissions and pollution concentrations at a detailed 1-meter resolution. This method developed by Dr Konstantin Kuznetsov simulates pollution dispersion in urban environments, accounting for factors like buildings, roads, and vegetation. In this second webinar, we will discuss the challenges of using coarse satellite imagery for urban pollution monitoring and how CFD modeling improves accuracy. We will also cover how combining Aerosol Optical Depth (AOD) data with ground-based measurements enhances emission retrievals, providing a clearer understanding of urban pollution patterns.

Session 1: Determining PM2.5 mass with Nephelometer optical measurements

Tue 3rd Sept, 2024; Wed 4th Sept, 2024 | Dr. Chong Li

Typically nephelometers use optical measurements to provide information about bulk particulate properties such as size and amount. AirPhoton nephelometers offer features that allow us to use GRASP to pull out additional information from the raw measurements such as size distribution and particulate mass. The SPARTAN network deploys our nephelometers around the globe alongside our filter based particle sampling stations. This provides us a unique data set to compare real time optical measurements and PM 2.5 retrievals with gravimetric based PM 2.5 measurements in a variety of environments and conditions. In our first webinar Dr. Chong Li will present the results of the work she has been doing with GRASP and machine learning to obtain PM2.5 dry mass estimates from AirPhoton nephelometer measurements deployed by the SPARTAN network.
