Subject: | NSA/VCEIL/C1 - vceil25K Instrument maintenance |
DataStreams: | nsavceil25kC1.a1, nsavceil25kC1.b1
|
Description: | The instrument was calibrated during this period. To achieve this, it was pointed in the
horizontal direction. |
Measurements: | nsavceil25kC1.a1: - Millivolts at internal ADC input (0 to 2500)(background_light)
- Aerosol backscatter coefficient at 355 nm(backscatter)
- Vertical visibility(vertical_visibility)
- range(range)
- Lowest cloud base height detected.(first_cbh)
- Second lowest cloud base height(second_cbh)
- Percentage of nominal factory setting (0 to 999%)(receiver_sensitivity)
- Altitude of highest signal(alt_highest_signal)
- Backscatter sum(sum_backscatter)
- Detection status. See details(detection_status)
- Third cloud base height(third_cbh)
nsavceil25kC1.b1: - Lowest cloud base height detected.(first_cbh)
