# NOAA SST: Sea Surface Temperature estimation

The two major inputs required for Potential Fishing Zone (PFZ) mapping are Chlorophyll and Sea Surface Temperature (SST) images. The information on Chlorophyll etc. is being derived from IRS-P4 OCM data. For SST NOAA-AVHRR data is the primary source of data. This module enables computation of Sea Surface Temperature (SST) using NOAA data supplied on CD either in LGSWOG or Level 1-B formats.

NOAA data needs to be loaded from this module as it downloads relevant ephemeris required for computation of SST.

The module facilitates:

· Downloading of NOAA AVHRR data in LGSWOG & Level 1-B Formats

· SST Computation for LGSWOG & Level 1-B Formats

· Panoramic Correction

· Provision for dynamic thresholds & coefficients

· Creation of Pseudo Color Table
