Simple tips on using the time slider: click on the time slider settings button (little wrench), select loop animation at the slowest speed (this will help load the images at first); choose the time zone of your liking, usually the time zone on your computer. Close the slider settings box and simply start the animation (second button from the left). Useful tip: once the images have been loaded, you can stop the animation, and click & drag the time slider, go back and forth and stop at specific times to follow a weather feature of particular interest to you.

You can go anywhere on the globe by typing in a location in the fly box and clicking the "Fly Here" button. The Google Earth navigation controls are located in the upper-right corner; you can zoom in and out, pan, rotate, ... to learn more, check out this tutorial.

The product: global cloud cover and precipitation rate, forecast by the Meteorological Service of Canada's Global Environmental Multiscale model ( GEM ), are projected onto google earth every 3 hours up to 48 hours; over North America, the higher resolution regional GEM model is used. Model forecasts are updated twice daily and available at 2am EST and 2pm EST.

The legend: cloud cover varies from 60% (grey) to 100% (white); precipitation rate is divided in 3 categories: light (less than 2.5mm/h, or 0.1 inches/hour), moderate (2.5 to 10.0 mm/h, or 0.1 to 0.4 inches/hour), heavy (more than 10mm/h, or 0.4 inches/hour). Note that, with this product, no information is given on the type of precipitation, which can either be rain, or snow or freezing rain. In fact precipitation rate always refers to the amount of water which would result if all the snow and/or ice, if any, was melted. For snow, there is usually a factor of 10 between the precipitation rate and the snowfall rate; for example, a precipitation rate of 1 mm/hr is equivalent to a snowfall rate of 10 mm/h, i.e. 1 cm/h.
