Instead of an in-person meeting for winter 2019–2020, HAQAST hosted a series of webinars that started in February of 2020. HAQAST members and contributors led informational talks on using NASA tools, assessing the health burden of PM2.5, the future of HAQAST, plus a special session co-hosted with the American Lung Association.

 4 pm EST — A Special Session with HAQAST and the American Lung Association — Watch Video
Tracking to Help You Breathe: Data and Best Practices for Tracing the Health Impacts of Smoke for the Public Health Community —Join HAQAST and American Lung Association for a session tailored specifically for the public health community as we discuss what satellite products can and can’t provide for your health-impact assessments. We’ll focus our efforts on data, resources, and best practices for tracking the health impacts of wildfire smoke. This session is co-sponsored by the American Lung Association.

2/25 Tuesday

 4 pm EST — Brad Pierce, Space Science and Engineering Center — Watch Video
The Brightest Idea: New Capabilities for Infusing Satellite Data into Environmental Applications–International (IDEA-I) —  This HAQAST2020 webinar will provide an overview of new capabilities that have been developed within Infusing satellite Data into Environmental Applications – International (IDEA-I). These new capabilities include using Suomi NPP and JPSS satellite measurements for:
1) Trajectory forecasts initialized with the NOAA Unique Combined Atmospheric Processing System (NUCAPS) carbon monoxide retrievals to predict continental scale pollution transport.
2) Trajectory forecasts initialized with the SSEC Dual-Regression infrared sounder retrieval algorithm ozone and water vapor retrievals to predict stratospheric intrusions.
3) High-resolution trajectory forecasts using the Visible Infrared Imaging Radiometer Suite (VIIRS) Enterprise Aerosol Optical Depth (AOD) retrievals to predict regional impacts of wild-fire smoke.
The case studies for this workshop will focus on using IDEA-I during the recent NASA/NOAA FIREX-AQ field campaign.

2/27 Thursday

Noon ESTMark Zondlo, Princeton University — Watch Video
How to Navigate Satellite Ammonia Measurements: Best Practices and Considerations — Over the past decade, satellite measurements of ammonia have become a widespread and routine data product. This talk will give an overview of data availability and characteristics, the differences between the various measurements, and their strengths and limitations. Finally, the talk will demonstrate ways in which satellite ammonia measurements can be used to help air quality managers and other stakeholders.
 4 pm ESTDaniel Tong, George Mason University — Watch Video
Every Breath You Take: Satellite-Aided Analysis of Dust Events — We will discuss the trend of dust storms and their impacts on air quality, human health, and transportation safety. Recent advances in observing and modeling dust storms will be covered as well as a tutorial on how to use satellite and ground data to identify dust events and analyze their contributions to regional haze and NAAQS exceedances.

3/3 Tuesday

Noon EST — Susan Anenberg and Dan Goldberg, George Washington University; Michael Brauer, Institute for Health Metrics and Evaluation — Watch Video
Taking a Wider View of NO2 Pollution: Estimating NO2’s Health Impacts from Local to Global Scales — Current studies assessing the global burden of disease from air pollution include only premature mortality from PM2.5 and ozone. Several recent meta-analyses of epidemiological studies around the world show that traffic-related NO2 pollution is associated with pediatric asthma incidence. We will present approaches for estimating NO2 exposure in cities worldwide using satellite remote sensing, as well as recent and ongoing research estimating the global burden of NO2 pollution on pediatric asthma incidence.

3/5 Thursday

Noon ESTJason West, University of North Carolina — Watch Video
Pollutant Concentration Mapping to Support Health Impact Assessment: Global Ozone Concentrations, and PM from California Wildfires — In this webinar, Jason West and colleagues from UNC Chapel Hill will discuss data fusion for air quality and health. We will discuss methods of combining ground measurements, satellite observations, and computer models to best construct maps of air pollutant concentrations. We will also present two applications of this data fusion: one for the global mapping of ozone for the Global Burden of Disease Assessment, and the second, a mapping of PM2.5 from the October 2017 California wildfires.
 4 pm ESTDaven Henze, University of Colorado at Boulder — Watch Video
Tracking PM2.5: How Models and Remote Sensing can be Used to Estimate Global Health Impacts of Ambient Fine Particulate Matter (PM2.5) — Satellite-observations provide a means of measuring atmospheric composition with global spatial coverage vastly greater than current air pollution monitoring networks. Atmospheric models can be used to interpret these remote-sensing observations, along with other measurements and geophysical proxies, to estimate surface-level ambient fine particulate matter concentrations (PM2.5). This talk will review how the science of developing these estimates has evolved as well as current applications of these techniques to investigate the global health burden associated with exposure to PM2.5.

3/10 Tuesday

Noon ESTMinghui Diao, San Jose State University — Watch Video
The Air in Your Community: Estimating Surface PM2.5 in California with a Fusion of Monitor Data, Satellite Observations, and Downscale Modeling — Join Minghui Diao for this webinar introducing the process for estimating community-level PM2.5. Diao will introduce the four main methods of generating publicly available PM2.5 data, the methods her team uses for fusing ground monitors data, satellite data, and downscale model simulations, and a demonstration of the dispersion model simulation, which is ultimately how to get a community-scale estimate of surface PM2.5.
 4 pm ESTJeremy Hess, University of Washington — Watch Video
Sneeze and Wheeze in a Low Earth Orbit: Forecasting Pollen from Space — Pollen allergies impose a substantial disease burden, and the pollen season in the US is lengthening due to climate change. Unfortunately, the pollen sensor network is somewhat sparse—but weather data can be used to estimate pollen concentrations in places without sensors. We have developed new, higher performing pollen forecasts for the US that can help protect public health—from space!—and this webinar will detail these new pollen forecasts.

3/12 Thursday

 4 pm ESTSusan O’Neill, USDA Forest Service, Pacific Northwest Research Station and Sean Raffuse, University of California Davis — Watch Video
Where There’s Smoke: Satellite Data for Smoke and Fire — Join Susan O’Neill for a webinar exploring some of the cutting-edge tools, data sets, and resources that are available for smoke forecasting, data fusion, health impact analysis, and other information for air quality and public health stakeholders interested in tracking or assessing the impact of wildfire smoke. This webinar will use as its case study a retrospective analysis of the Northern California wildfires of 2017 and 2018.
