NYCCAS Air Pollution Rasters
Citywide raster files of annual average predicted surface for nitrogen dioxide (NO2), fine particulate matter (PM2.5), black carbon (BC), and nitric oxide (NO); summer average for ozone (O3) and winter average for sulfure dioxide (SO2). Description: Annual average predicted surface for nitrogen dioxide (NO2), fine particulate matter (PM2.5), black carbon (BC), and nitric oxide (NO); summer average for ozone (O3) and winter average for sulfure dioxide (SO2). File type is ESRI grid raster files at 300 m resolution, NAD83 New York Long Island State Plane FIPS, feet projection. Prediction surface generated from Land Use Regression modeling of December 2008- December 2019 (years 1-11) New York Community Air Survey monitoring data.As these are estimated annual average levels produced by a statistical model, they are not comparable to short term localized monitoring or monitoring done for regulatory purposes.

Freshness
The publisher's promise
How the agency that publishes this data says it keeps the data current.
DormantNo automatic refresh
- Automatic refresh
No scheduled refresh runs for this dataset, and a refresh you ask for on this page is refused.
- The publisher set a regular schedule for this dataset but has not updated it for far longer than that schedule, so the automatic queue skips it. An hourly triage lifts this fence once the publisher updates it again, which takes up to about 7 hours 15 minutes. This fence does not stop a refresh you ask for on this page.
- Our catalog lists this dataset without keeping a copy of its rows, so the automatic queue has no copy to refresh. This fence refuses a refresh you ask for on this page.
