Ozone amounts at different heights (Suomi-NPP)

OMPS-NPP L2 NP Ozone (O3) Vertical Profile swath orbital
atmosphere NASA GES_DISC Level 2 active
In plain English

What it measures. How much ozone is present at different heights in the atmosphere, reported at 15 pressure levels in the upper atmosphere, plus the total ozone overhead and a measure of haze that absorbs ultraviolet light.

How it's made. Derived from ultraviolet light measurements by the OMPS instrument on the Suomi-NPP satellite, processed into vertical ozone profiles covering most of the globe each day.

How & where you'd use it. Monitoring the ozone layer and its vertical structure, and supporting research on atmospheric chemistry and air quality.

Official description

The OMPS-NPP L2 NP Ozone (O3) Total Column swath orbital product provides ozone profile retrievals from the Ozone Mapping and Profiling Suite (OMPS) Nadir-Profiler (NP) instrument on the Suomi-NPP satellite. The V8 ozone profile algorithm relies on nadir profiler measurements made in the 250 to 310 nm range, as well as from measurements from the nadir mapper in the 300 to 380 nm range. Ozone mixing ratios are reported at 15 pressure levels between 50 and 0.5 hPa. Additionally, this data product contains measurements of total ozone, UV aerosol index and reflectivities at 331 and 380 nm. Each granule contains data from the daylight portion of each orbit measured for a full day. Spatial coverage is global (-82 to +82 degrees latitude), and there are about 14.5 orbits per day, each has typically 80 profiles. The NP footprint size is 250 km x 250 km. The files are written using the Hierarchical Data Format Version 5 or HDF5.
