ClearDarkSky brings you:

Clear Sky Charts

Based on a numerical weather model, Clear Sky Charts are perhaps the most accurate and the most usable forecasters of astronomical observing conditions for over 1900 observatories and observing sites in North America.

North-American Seeing Observations Database

A web database which allows observers all over North America to enter observations of seeing (atmospheric turbulence which causes loss of telescopic resolution) and correlates them to seeing forecasts. The data is used to refine numerical forecast models.
