"Most of the NO2 pollution is at ground level, where ecosystems and people live and breathe."

Why does NASA measure NO2? NO2 is a criteria pollutant regulated by the U.S. EPA (and in many other countries) and can be harmful to humans. NO2 produces ozone, another pollutant, and produces acid rain, which is detrimental to ecosystems. Sources of NO2 are lightning, fires, soils, combustion of fossil fuels (e.g., cars, power plants, manufacturing). Most of the NO2 pollution is at ground level, where ecosystems and people live and breathe.

By the end of this session, you will be able to:

• Understand what satellites measure
• Describe the capabilities and limitations of satellite NO2 observations
• Find and download satellite imagery for NO2

Learning Objectives - 

• What is NO2?
• NASA Remote Sensing Basics
• Interpreting NO2 Imagery: Dos and Don'ts
• Downloading Data and Creating Imagery

Learners who have not completed the Fundamentals of Remote Sensing may not be prepared for the pace of the training.
