  • The image aspect ratio is now correct. The images should be square. This problem within the IDL engine was solved November 2007 by switching to the ferret application to generate the images.
  • Images were constructed by first using bi-cubic spline interpolation of the 5-day averaged OI SST grids (produced at 5-day intervals through GOMRMRP funding). The 5-day images were then interpolated linearly in time to produce daily images.
  • Information/validation regarding the gridded OI data and the (ASCII) grids are available J. Bisagni at the address above.
  • Images are 512 X 512 pixels, possess a resolution of ~7 km and are displayed as .GIF images.
  • The archive "switches" from NOAA-11 to NOAA-9 during September 1994 due to the NOAA-11 failure in September 1994.
  • The archive currently ends on 5 August 1995 due to the failure of NOAA-9
  • *NOTE*: These data are preliminary. Adjustment of data from each satellite (NOAA-9, NOAA-11 and NOAA-14) relative to sea truth values from NOAA data buoys will result in a final calibrated data set at sometime in the future.
  • The colorbar used is derived from so-called Pete's Palette, or pete24, and converted to an equivalent palette in the ferret scheme. (See petespalette.spk.

You can capture the gif image if your browser has that capability.

As a courtesy, please notify Jim Bisagni via email about your intent to use the SST OI fields, so that he may keep a record.
