Ozone at each height in the air, from NASA's TEMPO instrument on the Intelsat 40e satellite (beta)
What it measures. How ozone is distributed at different heights in the atmosphere, broken into 24 layers, plus total, stratospheric, and lower-atmosphere ozone amounts and their error estimates, on a regular grid.
How it's made. Made from the TEMPO instrument watching North America, by combining many Level 2 scans into gridded maps; this is an early 'beta' release.
How & where you'd use it. Helps study the vertical structure of ozone for air quality near the surface and the protective ozone layer higher up. As a beta product, it is mainly for early familiarization.

Official description
Ozone profile Level 3 (BETA) files provide ozone profile information on a regular grid covering the TEMPO field of regard for nominal TEMPO observations. Level 3 files are derived by combining information from all Level 2 files constituting a TEMPO East-West scan cycle. The files are provided in netCDF4 format, and contain information on ozone partial columns at 24 layers with the last layer 0-2 km above the surface, total, stratospheric, and tropospheric ozone columns, and their random-noise and total retrieval errors, a priori ozone profile and a prior error, effective cloud fraction and effective cloud top pressure. The re-gridding algorithm uses an area-weighted approach.
