Information on 220 Channel
AVIRIS Data Set
Location
This data is from the AVIRIS (Airborne Visible/Infrared Imaging Spectrometer) built by JPL and flown by NASA/Ames on June 12, 1992. The scene is over an area 6 miles west of West Lafayette. The scene is a subset of a significantly larger image file.
These data are calibrated data. In other words the data values in the scene are proportional to radiance. 1000 has been added to the calibrated data so that all data values in this scene are positive. To convert the scene data values (SDV) to radiance values (RV), one must first subtact 1000 and then divide by the gain_factor that JPL used which is 500.
RV = (SDV-1000) / 500.
The RV units are W * cm^-2 * nm^-1 * sr^-1.
This information is dated November 1992. It came with the tape documentation from JPL for this AVIRIS data.
Spectral Calibration
FWHM = Full Width Half Maximum. In other words it is the width of the spectral band.
