Previous version of 6S

6SV1.0B (May, 2005) 

1. Scalar (ignoring the effects of polarization)

1. Vector (accounting for polarization)

2. Fixed number of scattering angles (83), used for the specification of an aerosol phase function

2. Ability to vary the number of scattering angles (up to 100)

3. 10 node wavelengths

3. 20 node wavelengths

4. Fixed number of calculation layers (26) and angles (48)

4. Ability to change the number of calculation layers and angles

5. Default exponential vertical aerosol profile

5. Default exponential + user-defined (up to 50 layers in the height range 0-100 km) vertical aerosol profiles

 6. Several new subroutines, simulating measurements of the ALI, ASTER, ETM, HYPBLUE, VGT, and VIIRS instruments, have been integrated into the the vector 6S. Currently, the 6S list of satellite instruments include:

AATSR

ALI

ASTER

AVHHR

ETM

GLI

GOES

 HRV

HYPBLUE

MAS

MERIS

METEO

MODIS

MSS

POLDER

SeaWiFS

TM

VIIRS

VGT

 

The spectral response curves for all these instruments can be found in the 6S manual, version 3. The new subroutines were developed by Dr. T. Miura, University of Hawaii at Manoa, Honolulu, USA. Download the vector 6S with the new subroutines.

7. 6SV1.0B is participating in a joint vector/scalar RT code comparison project performed by the MODIS atmospheric correction group in collaboration with the NASA Goddard Space Flight Center. All information about this project, including the descriptions of the codes, conditions and results of the comparison, is posted at http://rtcodes.ltdri.org.
