Values may not reflect precisely reality.(Ver. 2.3, 14.6.2009)

For good seeing conditions look for dark blue colors in the cloud cover and green values in the Seeing Indices and Jet Stream
The estimated seeing indexes (1 & 2) range from 1 (poor) to 5 (excellent) seeing conditions. This value is computed based on the integration of turbulent layers in the atmosphere.
NEW! Estimation of seeing in arcseconds. This is a test prediction under development, uncalibrated for the time being.
Cloud cover ranges from dark blue (0% cover) to white (100% cover). Fog or very low cloud is not shown here (see pictocast for fog)
High jetstream speeds (>35m/s) usually correspond to bad seeing, as well as very low speeds (<5m/s). Color gives a hint.
Bad Layers have a Temperature Gradient > 0.5K/100m. The actual gradient is shown K/100m. The top and bottom height of the Bad layers is indicated by Bad Layers bot/top
