Yearly Tropospheric Nitrogen Dioxide Maps

OMI_trno2 - 0.10 x 0.10 Annual as Cloud-Optimized GeoTIFFs (COGs)
atmosphere NASA VEDA COG
In plain English

What it measures. Maps the average amount of nitrogen dioxide (NO₂) in the lower atmosphere each year, a pollutant from burning fuels, at fine global resolution.

How it's made. Built from NASA's OMI satellite instrument, packaged as web-friendly cloud-optimized image files.

How & where you'd use it. Supports tracking of long-term air-pollution trends across regions and years.
