AVIRIS-3 L2B Greenhouse Gas Enhancements, Facility Instrument Collection

Description

This dataset contains Level 2B (L2b) enhancements of greenhouse gasses (GHG) derived from imagery collected by the Airborne Visible / Infrared Imaging Spectrometer-3 (AVIRIS-3) instrument. Products include methane and carbon dioxide enhancements, each with per-pixel uncertainties and sensitivities to the background. Concentration enhancements are estimated from radiance measurements using a column-wise adaptive matched filter approach, which searches each pixel's radiance spectrum for deviations that are characteristic of a GHG's absorption spectrum. This is the NASA Earth Observing System Data and Information System (EOSDIS) facility instrument archive of these data. The NASA AVIRIS-3 is a spectral mapping system that measures reflected radiance at 7.4-nm intervals in the Visible to Shortwave Infrared (VSWIR) spectral range from 390-2500 nm.

22 False color image from orthocorrected radiance (left) and methane enhancement (right) from AVIRIS-3 data acquired on 2024-06-07 over the Gulf of Mexico about 10 km east of the Mississippi River Delta (approximately 29.10 latitude, -88.76 longitude). The enhancement image shows a methane plume associated with a oil rig visible in the upper central portion of false color image.
