ACORN5 ATMOSPHERIC CORRECTION CAPABILITY

The Atmospheric CORrection Now (ACORN) software package provides an atmospheric correction of Hyperspectral and Multispectral data measured in the spectral range from 350 to 2500 nm.

ACORN is designed to work with all airborne and spaceborne calibrated hyperspectral and multispectral data types including HYPERION, ASTER, LANDSAT, ETM, AVIRIS, SPOT, IKONOS, etc.


ACORN provides advansed atmospheric correction for both Hyperspectral and Multispectral data and provides the following specific modes of Atmospheric Correction:

Mode 1 Radiative transfer atmospheric correction of calibrated hyperspectral data.

Mode 1pb Mode 1 for pushbroom imaging spectrometer with cross-track spectral calibration variation.

Mode 1.5 Radiative transfer atmospheric correction of calibrated hyperspectral data with water vapor and liquid water spectral fitting

Mode 1.5pb Mode 1.5 for pushbroom imaging spectrometer with cross-track spectral calibration variation.

Mode 2 Single spectrum enhancement of a hyperspectral atmospheric correction.

Mode 3 Atmospheric correction using the empirical line method for hyperspectral data.

Mode 4 User specified convolution of hyperspectral data to multispectral data.

Mode 5 Radiative transfer atmospheric correction of calibrated multispectral data.

Mode 5.5 Radiative transfer atmospheric correction of calibrated multispectral data with independently know water vapor image for spatially varying water vapor correction

Mode 6 Single spectrum enhancement of a multispectral atmospheric correction.

Mode 7 Atmospheric correction by the empirical line method for multispectral data.


ACORN include full documentation include a tutorial with examples of each mode of operation.

ATMOSPHERIC CORRECTION APPROACH

ACORN uses look-up-tables calculated with the Modtran 4 radiative transfer code to model atmospheric gas absorption as well as molecular and aerosol scattering effects. These modeled atmospheric characteristics are used to convert the calibrated sensor radiance measurements to apparent surface reflectance.The technique uses a fast and accurate look-up-table approach to calculate water vapor amounts on a pixel-by-pixel basis. The user may choose to use the water vapor absorption bands at 940 or 1150nm or both for the water vapor derivations. Additionally the user may input a visiblity or ask ACORN to attempt to estimate the visiblity from the data. A set of sophisticated artifact suppression options are included in the ACORN software. Full documentation, a set of examples and a tutorial are provided with ACORN.
