| Subject: | TWP/VCEIL/C3 - Degraded Sensitivity, Limited Range |
| DataStreams: | twpvceil25kC3.a1, twpvceil25kC3.b1
|
| 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. |
| Measurements: | twpvceil25kC3.a1: - Third cloud base height(third_cbh)
- Lowest cloud base height detected.(first_cbh)
- Second lowest cloud base height(second_cbh)
- Aerosol backscatter coefficient at 355 nm(backscatter)
- Vertical visibility(vertical_visibility)
- Altitude of highest signal(alt_highest_signal)
twpvceil25kC3.b1: - Lowest cloud base height detected.(first_cbh)
- Vertical visibility(vertical_visibility)
- Aerosol backscatter coefficient at 355 nm(backscatter)
- Second lowest cloud base height(second_cbh)
- Third cloud base height(third_cbh)
- Altitude of highest signal(alt_highest_signal)
