A Bio-Optical Model for retrieval of Oceanic Chlorophyll
We have developed one R_{rs} --> C algorithm that computes the
chlorophyll concentration (C) for a given set of remote sensing
reflectances ( R_{rs}).
Our approach has three attractive features:
- We do not invoke the "isotropic" assumption, because we use a coupled
air-ocean radiative transfer model (CAO-DISORT);
- We avoid uncertainties associated with atmospheric contributions,
because we use a transparent atmosphere in this case (no atmosphere);
- We have validated our approach against the R_{rs} <--> C data provided
in the SeaBASS data base for a large range of chlorophyll concentrations
and solar zenith angles.
Current version:
Version 1.2:

Click on the link to download the code for the algorithm. Included in this package is
the necessary LUT (Look-Up Table) and an example input and output file.
The computer program (Fortran 90) implementing the algorithm can be viewed
without downloading the entire package
by clicking
HERE.
There is a
README file for the program as well.
NOTE: The bio-optical model package has been updated to version 1.2.
If you downloaded version 1.0, between February 7th and February
15th, then the LUT file "rrs_16_5_9.dat" contains a few errors. Version
1.1 contains the corrected LUT file as well as the
old broken file called "rrs_16_5_9-donotuse.dat". Version 1.2 only
contains the corrected LUT, renamed "rrs_LUT.dat". Older versions are still
available for download below.
Older versions:
Version 1.1:
stamnes_rrs-1.1.tar.gz
Version 1.0:
stamnes_rrs-1.0.tar.gz
