Weekly NO2 Cycle Based on OMI Satellite Data

OMI data from NASA Giovanni

The weekly NO2 cycle is entirely due to man-made sources

In automobile-dominated Philadelphia, Friday exceeds Sunday by 50%

In the power plant-dominated Ohio River Valley, the difference is less than 10%

Thus, the OMI data offer a measurement-based NOx emission characterization

Friday Sunday
