Ozone amounts at different altitudes (Sentinel-5P)

Sentinel-5P TROPOMI Ozone Profile 1-Orbit L2 30km x 30km V2 (S5P_L2__O3__PR_HiR) at GES DISC
atmosphere NASA GES_DISC Level 2 active
In plain English

What it measures. How much ozone sits at different altitudes in the atmosphere, building a vertical profile rather than a single total amount, at a fairly detailed map scale.

How it's made. Calculated from the light spectra recorded by the TROPOMI instrument on Europe's Sentinel-5P satellite, processed one orbit at a time into ozone profiles.

How & where you'd use it. Useful for tracking the vertical distribution of ozone, including the protective ozone layer high up and ozone lower in the air; it supports air-quality and atmospheric studies.

Official description

Starting from August 6th in 2019, Sentinel-5P TROPOMI along-track high spatial resolution (~5.5km at nadir) has been implemented. S5P_L2__O3__PR_HiR data collection contains the high spatial resolution products. The Sentinel-5 Precursor (Sentinel-5P or S5P) satellite mission is one of the European Space Agency's (ESA) new mission family - Sentinels, and it is a joint initiative between the Kingdom of the Netherlands and the ESA. The sole payload on Sentinel-5P is the TROPOspheric Monitoring Instrument (TROPOMI), which is a nadir-viewing 108 degree Field-of-View push-broom grating hyperspectral spectrometer, covering the wavelength of ultraviolet-visible (UV-VIS, 270nm to 495nm), near infrared (NIR, 675nm to 775nm), and shortwave infrared (SWIR, 2305nm-2385nm). Sentinel-5P is the first of the Atmospheric Composition Sentinels and is expected to provide measurements of ozone, NO2, SO2, CH4, CO, formaldehyde, aerosols and cloud at high spatial, temporal and spectral resolutions. This product contains ozone profile with a vertical resolution of 6 km and a horizontal resolution of 30x30km2 observed at about 13:30 local solar time from spectra measured by TROPOMI
