Haze layers at different heights, monthly (Suomi-NPP)

OMPS-NPP L3 LP Aerosol Extinction Vertical Profile 5 x 15 deg lat-lon grid multi-wavelength monthly V1 (OMPS_NPP_LP_L3_AER_MONTHLY) at GES DISC
atmosphere NASA GES_DISC Level 3 active
In plain English

What it measures. How much tiny airborne particles (aerosols) dim light at different heights high up in the atmosphere, given as monthly profiles from the ground up to about 41 km at six wavelengths of light.

How it's made. Derived from the OMPS Limb-Profiler sensor on the Suomi-NPP satellite, which looks sideways at the edge of the atmosphere, with the data averaged over each month onto a coarse map grid.

How & where you'd use it. Used to track haze and particles in the stratosphere, such as plumes from volcanic eruptions or wildfires, and how that layer changes month to month.

Official description

The OMPS-NPP L3 LP Aerosol Extinction Vertical Profile 5 x 15 deg lat-lon grid multi-wavelength monthly (AER) product contains the retrieved aerosol extinction coefficients measured by the Ozone Mapping and Profiling Suite (OMPS) Limb-Profiler (LP) sensor on the Suomi-NPP satellite. The AER product measures stratospheric aerosol abundance and evolution at 6 wavelengths (510, 600, 675, 745, 869 and 997 nm) to complement the OMPS LP measurements of stratospheric and mesospheric profile ozone. Each granule contains data from the daylight portion of each orbit averaged over an entire month in 5 x 15 deg lat-lon grids. Spatial coverage is global (-90 to 90 degrees latitude). The profiles are gridded from the ground up to about 41 km with a vertical resolution of the 1.0 km. The files are written using the Hierarchical Data Format Version 5 or HDF5.
