Environment Canada http://weatheroffice.ec.gc.ca
The nation's official source of weather and environmental data. Includes dewpoint
temperature data.
Clear Dark Sky http://cleardarksky.com
Localised sky condition predictions by Attila Danko based on weather (cloud cover,
temperature, and humidity) data as well as Moon position and phase. Brilliant!
CSAC http://ClearSkyAlarmClock.com
Already, the clear sky predictors by Attila are pretty amazing. But Mark Casazza
has added an outstanding feature: you can receive an email notification of possible
clear skies! Based on criteria you specify, his system will send you a brief email,
as an "alarm," so you can prep your 'scope. Now works with multiple
sites!
GOES http://adds.aviationweather.gov/satellite/
Provided by NOAA's National Weather Service Aviation Weather Center. The animated
GOES satellite infrared colour and black & white visible images help one determine
what has just happened and allow some extrapolation.
College duPage http://weather.cod.edu/analysis/
The Next Generation Weather Lab is used by storm chasers! Very good satellite
imagery, visible and infrared again, plus water vapour, radar, and so on.
Intellicast http://www.intellicast.com
Referred to this site by an RASC member. Features animated infrared satellite
views over large areas of the continent. The New
York state regional report works well for Toronto and region. Or Michigan.
Requires Java.
IDA http://darksky.org
The International Dark-Sky Association is a US organisation committed to reducing
light pollution. Here here!
Lights Out Toronto http://www.toronto.ca/lightsout/
The city is trying to reduce migratory bird deaths by encouraging businesses and
individuals to turn off lights and reduce light pollution by using improved light
designs. This is good news for astronomers.
National Dark Sky Week http://ndsw.org/
US-based web site encouraging people to turn off their unnecessary lights during
Astronomy week, which centres around International Astronomy Day, on April 21.
