This list brings together the Web sites that are used at the
DDO to predict weather changes.
- NASA viewer
of the IR images from GOES-8. This is our most frequently used
site. However, it stops working after midnight for a few hours,
probably because the satellite goes into the Earth shadow (during this
time use images from GOES-10). Turn off the colour enhancement to see
thin clouds.
- GOES-8
and GOES-10 images are displayed rectified in this UNISYS site. The
service is convenient in that GOES-10 images are automatically shown
during the after-midnight break in the GOES-8 service.
- Real-time
weather service is reliable source showing the same data as the two
sites above, but in a different format. Select the IR data during the
night as the visual channel is then obvioulsy totally black.
- Intellicast gives mostly the location of rain and storms as seen by
the US radar. This site is now very commercial but may be
of use.
- Weather
models from the Canadian Meteorological Centre, updated every 3
hours and accessible via a nice interface specifically tailored for
observations at DDO.
- Weather
models from the German Weather Office. Reputed to be very
reliable. It helps to know the German language. Go to Top Karten and then
select a model (e.g. GFS) then the geographic are (e.g. N-Amerika). The menu at the
upper part of the page gives various data.
- RAMSDIS gives
access to many different weather maps.
- The
Environment of Canada Weather Office - various "products" of mixed usefullness.
- The Weather
Network, the same as on the Canadian TV Weather Channel.
- The
300 mb jet stream over North America. Cirrus clouds usually form
along the jet stream.
