Ozone at different altitudes (TEMPO, 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.
