All daily NOAA-11 Advanced Very High Resolution Radiometer satellite passes from 1 October 1993 on (generally 2 passes per day) have been remapped (earth-located) to our Georges Bank/Gulf of Maine "standard" region (given below) in a Mercator projection. Our standard region is bounded by:
Precision navigation of each image to within 1 or 2 pixels has begun with the image file names receiving a ".nav" file extension when navigation is completed. Be aware that "un- navigated" images (".rmp" file extension) may possess navigation errors of up to 6 or 7 pixels in the meridional and/or zonal directions. Note that only ".nav" files are being served here at this time.
Daily remapping and weekly backups of these data will continue until after completion of the GLOBEC and Gulf of Maine field programs are completed. Each of these images are in University of Miami XDR04 format, consisting of an 8-bit, 512 X 512 pixel binary image, preceded by three 512-byte header records. The size of each image file (in uncompressed form) is ~250K bytes.
Up until July 2012, these images were uncompressed and converted from DSP compressed files to gif images via the ferret application for display by your favorite browser, such as Firefox, Internet Explorer, and Safari. Starting July 29, 2012, the gif images were served from files converted to gif images in a batch operation by Kent Gardner at UMass/Dartmouth and served online without using ferret.
The center latitude is 42.309 degrees North and the center longitude
is 67.830 degrees West. The slope and Y-intercept for converting the 8-bit image byte values to SST in degrees Centegrade are 0.125 and 0, respectively.
The equation information (slope + intercept) are IDENTICAL for both the OI and realtime images, with SSTs going from 0 through 31.875 degrees Centigrade.
Near real-time, daily, satellite-derived sea surface temperature (SST) data, which cover Georges Bank and the Gulf of Maine were also available for browsing over the Internet in the Xbrowse format. However, this software is no longer available.
These images are no longer viewable via DODS which has been replaced by OPeNDAP. The images cannot be viewable via OPeNDAP either, since the University of Miami's DSP format is no longer supported.
You can capture the gif image as most browsers have that capability. In addition, you can download the DSP compressed file for your onw use using the link on the web page. Please contact Dr. James Bisagni directly.

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. |
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). |
