Air Quality Dashboard: A new public-facing dissemination system for trends in air quality and its impact on public health and agriculture

Rajesh Kumar (RAL), Forrest Lacey (ACOM) and Jennifer Boehnert (RAL), NCAR

We have created a user-friendly ESRI based air quality dashboard to communicate air quality information from a high-resolution (12 x 12 km 2 ) reanalysis developed over the contiguous US (CONUS) from  2005 2018. The dashboard maps and communicates the historical modeled air quality data and its impacts on public health and agriculture aggregated at the state and county level. A Stream lit python-based website has also been developed where users can select based on time and space and download aggregated and extracted data as a CSV file. The air quality reanalysis is generated using a newly developed chemical data assimilation system that simultaneously assimilates aerosol optical depth (AOD) retrievals from the Moderate Resolution Imaging Spectroradiometer (MODIS), and carbon monoxide (CO) retrievals from the Measurement of Pollution in the Troposphere (MOPITT) in the Community Multiscale Air Quality (CMAQ) model driven by the Weather Research and Forecasting (WRF) model.
