Brief Description | The aircraft is in another part of the cloud and way below it. |

This day (28 June 2001) was a good example of a thick cloud case.
The rule for thick clouds defines: At least 4500 ft. (1.4 km) deep and any part colder than 0 deg C.
During the time of the Citation mission (1930-2030Z), the cloud averaged 4km thick and the ambient temperature was -8 deg C at the aircraft's altitude. So I think this case meets the definition of a thick cloud hazard.
During the entire flight, the electric field was negligible and the dominant particles were small.
We will be looking at plots that are linked to the June 28, 2001 homepage.
