About

A research project on the air over the Bay

Nitrogen in the air settles into the Chesapeake Bay as nitrate and feeds the algal blooms behind its low-oxygen dead zones, in a watershed home to more than 18 million people. This project asks how well open ground and satellite measurements can estimate ground-level NO₂ and ozone across the Bay, hour by hour, and shows the answer honestly, including where it falls short.

Research prototype: not for health or regulatory decisions.

Scope

What this is, and isn't

It is a research prototype: an LSTM and simpler models estimating surface NO₂ and O₃ on a 0.1° grid, scored openly against EPA monitors, with every number downloadable.

It isn't an air-quality forecast service, a health tool, or an official data product. Its skill has only been shown near monitors, and it estimates the next hour only, not days ahead.
