Nitrogen dioxide (NO2) is unhealthy to breathe and is a necessary ingredient for the formation of unhealthy levels of surface ozone [NASA Air Quality]. NASA Aura's OMI sensor has been monitoring NO2 data since 2004 and has been used in a variety of health and air quality applications. The TROPOMI instrument onboard Sentinel-5P, launched in 2017, represents a significant improvement in spatial resolution over OMI. It will be better-suited for many applications currently using OMI data, including monitoring air pollution. In this advanced webinar, attendees will learn how to access and analyze TROPOMI data and learn about its applications.
By the end of this training, attendees will be able to:
- Understand the available data products
- Access and download TROPOMI data
- Analyze the data using Python tools
This webinar is intended for end-users who are already familiar with satellite observation capabilities and have used online image archives or analysis tools at basic to intermediate levels for air quality applications, such as emissions estimation using satellite observations.
- Parts 1 & 2 will be one hour long.
- Part 3 will be 2 hours long and include an opportunity for attendees to practice using TROPOMI data.
This webinar will primarily consist of going through an exercise on using updated python codes to work with TROPOMI data. This will include reading, mapping, extracting over a point location, gridding the data, and dumping the data to a CSV file.
