Discussion

Analysis of NO2 from satellite data and ground measurements, indicating strong potential for health applications.

Satellite data from TROPOMI and TEMPO demonstrate a strong ability to monitor NO2 levels effectively across different locations.
Frequency distributions show TROPOMI and TEMPO have a JSD indicating better agreement at non-roadway monitors than interstates.
Seasonal analysis reveals that winter distributions align closely while summer shows more variation in NO2 levels.
Both satellite instruments demonstrate their capacity to support ground-based monitors, enhancing regulatory and public health efforts.

Acker et al. (2025) studied this question.
