Air temperature at different altitudes (Suomi-NPP, daily)

OMPS-NPP LP L2 Temperature Vertical Profile swath daily 3-slit V1.0 (OMPS_NPP_LP_L2_Temp_DAILY) at GES DISC
atmosphere NASA GES_DISC Level 2 active
In plain English

What it measures. Air temperature high up in the atmosphere, from roughly ground level up to about 60 km, covering the stratosphere and the start of the mesosphere.

How it's made. Produced from the Limb-Profiler sensor on the Suomi-NPP satellite, which looks sideways through the edge of the atmosphere; the readings are turned into vertical temperature profiles for each daylight orbit over a full day.

How & where you'd use it. Useful for studying the upper atmosphere, tracking how its temperature shifts with seasons and over years, and feeding climate and ozone research.

Official description

The OMPS-NPP LP L2 Temperature Vertical Profile swath daily 3-slit collection contains the temperature profile measured by the Ozone Mapping and Profiling Suite (OMPS) Limb-Profiler (LP) sensor on the Suomi-NPP satellite. The product measures the temperature in the stratosphere and lower mesosphere. Each granule contains data from the daylight portion of each orbit measured for a full day. Spatial coverage is global (-90 to 90 degrees latitude), and there are about 14.5 orbits per day, the data from the center of the LP three slits are used to make a vertical profile. The profile is measured from the ground up to about 60 km with a vertical resolution of the retrieved profiles of approximately 1.8 km. The data are written using the Hierarchical Data Format Version 5 or HDF5.
