Description

The OMPS-N20 L2 NM Aerosol Index swath orbital V2 for Near Real Time. For the standard product see the OMPS_N20_NMUVAI_L2 product in CMR .The aerosol index is derived from normalized radiances using 2 wavelength pairs at 340 and 378.5 nm. Additionally, this data product contains measurements of normalized radiances, reflectivity, cloud fraction, reflectivity, and other ancillary variables.
