Rain

During rain the ceilometer signals vary significantly

 

We observed an interesting pattern over and over in the lower (<3 km) region. The signals of the ceilometers differs there of factor 3-6. However most of them have the similar profile patterns (only shifted), exept the CHX080082. These periods are associated to rain. It happened i.e. on 8th June17 June, 18 June, 22 June, and 29th June .
