A processing module is included in ATCOR-3 for hyperspectral sensors such as Hyperion or CHRIS/Proba.
These sensors may not have stable spectral calibration or may offer multiple spectral modes. Therefore,
atmospheric LUTs frequently must be recalculated to reflect updated spectral calibration. A simple interface
is available to specify required sensor information (number of channels, field of view, and channel spectral
response curves). This information is used to calculate sensor-specific atmospheric LUTs from the monochromatic
atmospheric database supplied with the add-on module. Although mainly intended for hyperspectral sensors, the
module can also be used to define new multispectral instruments. The distribution includes examples of sensor
definition files for CHRIS (hyperspectral template), ASTER (multispectral template), and Hyperion.

Examples of supported hyperspectral satellite sensors

  • CHRIS – Compact High Resolution Imaging Spectrometer, 400–1000 nm, 17–34 m depending on mode; modes 1, 3, 4, 5 supported. (Ref: ESA Proba/CHRIS)
  • Hyperion – 30 m, swath 7.5 km, 242 bands. (Ref: USGS EO-1 Hyperion)

Atmospheric Database

  • Atmospheres with different vertical profiles of pressure, air temperature, humidity, ozone content (water vapor columns 0.4 to 5.0 g/cm², sea-level to space).
  • Various aerosol types (rural, urban, maritime, desert).
  • Visibilities (surface meteorological range) 5 to 120 km (hazy to very clear).
  • Ground elevations 0 to 4.0 km (extrapolated for higher elevated regions).
  • Solar zenith angles 0 to 75 degrees.
  • Tilt geometries (e.g., SPOT, Ikonos) with tilt angles up to 50 degrees are supported.
  • Discrete relative azimuth angles 0 to 180 degrees (increment 30 degrees) for atmospheric LUTs of tilt sensors; interpolation applied if necessary.
  • Capability for mixing of atmospheres (water vapor, aerosol).

The sensor-specific database is available for standard multispectral sensors (e.g., Landsat TM, ETM+, SPOT, IRS-P6).
For sensors with varying spectral modes (e.g., CHRIS), the hyperspectral add-on module is recommended, allowing user-defined
sensors. Two monochromatic spectral databases are delivered with ATCOR-3 to generate the required sensor-specific atmospheric LUTs:
one for nadir-viewing sensors with spectral sampling of 0.4 nm from 350 nm to 2550 nm; and a second intended for CHRIS including
nadir plus tilt geometries of 35 degrees and 55 degrees with a 1 nm sampling grid covering 400 nm to 1050 nm.

The databases are calculated with the Modtran-5 code using the scaled DISORT option, and a correlated-k algorithm in atmospheric
absorption regions.
