Haze, dust and smoke in the air, live (Aura)

OMI/Aura Near UV Aerosol Optical Depth and Single Scattering Albedo 1-orbit L2 Swath 13x24 km V004 (OMAERUV) NRT
atmosphere NASA OMINRT Level Not provided
In plain English

What it measures. The same airborne-particle product as its standard sibling, measuring how much dust, smoke, and haze dim and absorb ultraviolet sunlight, but delivered quickly.

How it's made. A near-real-time version of the Aura Ozone Monitoring Instrument aerosol product, produced from one orbit at a 13x24 km footprint.

How & where you'd use it. Its speed makes it handy for watching unfolding events like dust outbreaks and wildfire smoke close to the time they happen.

Official description

The Aura Ozone Monitoring Instrument level-2 near UV Aerosol data product OMAERUV (Version 004) NRT is available from the NASA OMINRT for the public access. The OMAERUV retrieval algorithm is developed by the US OMI Team Scientists. Dr. Omar Torres (GSFC/NASA) is the principal investigator of this product. The OMAERUV product contains Aerosol Optical Depth, Aerosol Single Scattering Albedo, Absorption Optical Depth, UV Aerosol Index, and Aerosol Optical Depth over clouds at three wavelengths (354, 388, and 500 nm), and other ancillary and geolocation parameters, in the OMI field of view (13x24 km). The OMAERUV files are stored in the version 4.0 Network Common Data Form (NetCDF). Each file contains data from the day lit portion of an orbit (~53 minutes). There are approximately 14 orbits per day. The maximum file size for the OMAERUV data product is about 17 Mbytes.
