Subject: | NSA/VCEIL/C1 - Occasional Data Transmission problems |
DataStreams: | nsavceil25kC1.00, nsavceil25kC1.a1, nsavceil25kC1.b1
|
Description: | During this period, there were occasional data transmission problems that lead to cut-off
data packets at times. These disappeared after ceilometer computer were replaced. |
Suggestions: | Interpolate between brief periods of missing data |
Measurements: | nsavceil25kC1.b1: - Millivolts at internal ADC input (0 to 2500)(background_light)
- Percentage of nominal factory setting (0 to 999%)(laser_pulse_energy)
- lon(lon)
- Vertical visibility(vertical_visibility)
- Aerosol volume backscattering coefficient at 355 nm(backscatter)
- Degrees from vertical (-15 to +90)(tilt_angle)
- Third cloud base height(third_cbh)
- base time in epoch(base_time)
- Percentage of nominal factory setting (0 to 999%)(receiver_sensitivity)
- North Latitude(lat)
- Distance to the center of the corresponding range bin(range)
- 6 character string describing instrument measurement parameters(measurement_parameters)
- -180.0 - +180.0(alt)
- Raw data filename(filename)
- Window contamination(window_contamination)
- Detection status.(detection_status)
- Time offset from base_time(time_offset)
- Second lowest cloud base height(second_cbh)
- Altitude of highest signal(alt_highest_signal)
- Laser temperature(laser_temperature)
- Warning, alarm, and internal status information(status_string)
- Sum of detected and normalized backscatter(sum_backscatter)
- Flag indicating aeri retrieval status(status_flag)
- Lowest cloud base height detected(first_cbh)
