These
images were all obtained with the direct readout satellite
system in Mr. Baxter's room. The system consists of a
quadrafiler antenna on the roof, a 486 computer with a qfax
card, and software. All images are from NOAA satellites and
are unique to our location and station. The first image,
Manicougan, is interesting because it shows a circular white
ring in southeastern Canada. The ring is actually fog laying
in a low area that was probably caused by a meteorite
impact. This illustrates how some things become visible with
a satellite that otherwise are unobserved. The second image
is an IR, or infrared, image. It only shows heat but note
that water and land and the Bay are quite visible. This is
an early April picture and note the cool water temperature
from spring snow melt in the mountains running into the Bay.
The third image is a visible light image. Note the
geographic features present. Why do you think rivers show up
so well? What's the smallest thing visible? How could you
find out how big each pixel is?
