Approach:

Check for optimal conditions:


Clouds

all leves

Seeing

Jet Stream

Bad Layers

arc.sec.

Index 1 and 2

0

<1.0

4 - 5

< 10 m/s

<= 05K/100m


  • Look for dark blue colors in the cloud cover and green values in the seeing indexes and jet stream for good seeing conditions. 
  • The estimated seeing indexes (1 & 2) range from 1 (poor) to 5 (excellent) seeing conditions. These values are computed based on the integration of turbulent layers in the atmosphere. 
  • Cloud cover ranges from dark blue (0%) to white (100%). Fog or very low clouds are not shown here (see pictocast for fog). 
  • High jet stream speeds (>20m/s) usually correspond to bad seeing. 
  • Bad layers have a temperature gradient of more than 0.5K/100m. The top and bottom heights of the bad layers are indicated.
