Notes
- 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.

email about your intent to
use the SST OI fields, so that he may keep a record.
