Dynamics Explorer - 1 (DE-1)
Spin-Scan Auroral Imager (SAI)
Survey images from the Dynamics Explorer - 1 Spin-scan Auroral Imager's
(DESAI) Vacuum Ultra-Violet (VUV) photometer (labeled "C") are available
as GIFTM images and are sorted by year
(1981 to 1991) and Day-of-Year (DOY). For each DOY, there are
sub-directories that correspond to the VUV photometer's
filter number and name used with that sequence
of images. In the filter sub-directory the image filenames are labeled
by the time of the first SAI image in the sequence, i.e.,
HHMMSS_C.gif. E.g., the 1981/266 136W filter images starting at
23:32:00 UT are found in the file /1981/266/1_136W/233200_C.gif.
To request any DESAI science-level data please send e-mail to
Mary Rae Dvorsky.
Alternatively, you can use the NASA Data Archive and Distribution Service's
automated request system at the NASA Space Science Data Center (NSSDC) to
retrieve DESAI MAF data.
DESAI Image Analysis Software
A package of sample image analysis programs in FORTRAN is available to
demonstrate how to read and manipulate DESAI images in the MAF format.
This also includes complete documentation on the MAF image format.
Three different compressed ZIP binary archives are currently available.
If you do not have ZIP software, but have another type you can contact
Dynamics Explorer and SAI Related Photo Gallery
A gallery of Dynamics Explorer related
images and photographs collected over the years is available for
downloading. Most are scans of photgraphs or logos.
