ocm_tsm - Computes the total suspended matter product from Oceansat-1 OCM using three calibrated channels (OCM channels 3, 5 & 6).

This function requires a TeraScan Oceansat license.

SYNOPSIS

ocm_tsm   [ inputfile outputfile ]
ocm_tsm   [ outputfile ... directory ]

There are no parameters.

DESCRIPTION

The function ocm_tsm calculates the reflectance for OCM channels 3, 4, & 5 in the 490, 555, and 670 nm wavelengths. The reflectances are utilized in the ISRO total suspended matter (mg/L) algorithm to derive the output product. Input is calibrated and well navigated OCM channels 3, 5, & 6.

The ocm_tsm function derives the Total Suspended Matter variable and writes it to the output dataset:
 

Variable Units Description
