Data, Method, and Code

Data

• Sentinel-5P L2
• S5P-NO2-tropno-daily-check
• ERA5 hourly data on single levels from 1979 to present
• U.S. Vessel Traffic Data

Method

• U.S. AIS ship data is downloaded from MarineCadastre.gov and satellite/weather data are accessed from the Euro Data Cube Public Collections.
• Ship data is resampled into hourly ship density and converted into NetCDF files as the input of visualization and machine learning.
• An interactive tool is developed to show ship activities and NO2 pollution by combining all available data together.
• The analysis generated by the interactive tool can help us understand how COVID-19 and weather affect the patterns between shipping dynamics and observed air quality parameters.
• The pandemic and machine learning provide the unique opportunity of identifying shipping routes and exploring the effects of ship pollution over heavily populated areas.
