| Subject: | TWP/VCEIL/C3 - Degraded Sensitivity, Limited Range |
| DataStreams: | twpvceil25kC3.b1, twpvceil25kC3.a1
|
| Description: | The Darwin ceilometer was displaying a cross-talk warning during this
period. This causes degraded sensitivity and the inability of the
ceilometer to identify cloud heights that are higher the about 2 km. |
| Suggestions: | Use data during this period only for lower cloud studies. |
| Measurements: | twpvceil25kC3.b1: - Vertical visibility(vertical_visibility)
- Aerosol volume backscattering coefficient at 355 nm(backscatter)
- Third cloud base height(third_cbh)
- Second lowest cloud base height(second_cbh)
- Lowest cloud base height detected(first_cbh)
- Altitude of highest signal(alt_highest_signal)
