Dataset brief description

1996 daily cloud-free, AVHRR-derived, optimally interpolated SST images

Dataset description

PI: J. J. Bisagni
Dataset: Daily Cloud-Free, AVHRR-Derived, Optimally Interpolated (OI) SST images

OI SST Images

Daily AVHRR-derived OI SST images for the GOMRMRP & U.S. GLOBEC Georges Bank Program studies

Domain: 39.107 - 45.511 degree North latitude, 63.504-72.164 degree West longitude,

4 October 1993 - 31 December 1998

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.

Downloading the image

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.

Processing description

The image aspect ratio is not quite right. The image should be square. This problem within the IDL engine will be solved shortly (May 20, 2002)
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.

Instruments List

Advanced Very High Resolution Radiometer:

Short name: AVHRR

PI supplied instrument name: Advanced Very High Resolution Radiometer

Dataset-specific description:

Advanced Very High Resolution Radiometer (AVHRR). Carried aboard the National Oceanic and Atmospheric Administration`s (NOAA) Polar Orbiting Environmental Satellite series, the AVHRR sensor is a broad-band, 4- or 5-channel scanning radiometer, sensing in the visible, near-infrared, and thermal infrared portions of the electromagnetic spectrum.
Additional description.

Generic description:

"The AVHRR instrument consists of an array of small sensors that record (as digital numbers) the amount of visible and infrared radiation reflected and (or) emitted from the Earth's surface" (more information).
