Subject: | NSA/C2/VCEIL - Occasional Data Transmission Problems |
DataStreams: | nsavceil25kC2.b1, nsavceil25kC2.a1, nsavceil25kC2.00
|
Description: | A combination of problems lead to occasional short period loss (usually lesss than 2
minutes) of data for ceilometer during this period. |
Suggestions: | Interpolate data between short two minute gaps |
Measurements: | nsavceil25kC2.a1: - -180.0 - +180.0(alt)
- Time offset from base_time(time_offset)
- Detection status.(detection_status)
- Aerosol volume backscattering coefficient at 355 nm(backscatter)
- base time in epoch(base_time)
- Window contamination(window_contamination)
- 6 character string describing instrument measurement parameters(measurement_parameters)
- Vertical visibility(vertical_visibility)
- Millivolts at internal ADC input (0 to 2500)(background_light)
- North Latitude(lat)
- Lowest cloud base height detected(first_cbh)
- Distance to the center of the corresponding range bin(range)
- Warning, alarm, and internal status information(status_string)
- Percentage of nominal factory setting (0 to 999%)(receiver_sensitivity)
- lon(lon)
- Altitude of highest signal(alt_highest_signal)
- Flag indicating aeri retrieval status(status_flag)
- Degrees from vertical (-15 to +90)(tilt_angle)
- Second lowest cloud base height(second_cbh)
- Third cloud base height(third_cbh)
- Percentage of nominal factory setting (0 to 999%)(laser_pulse_energy)
- Laser temperature(laser_temperature)
- Sum of detected and normalized backscatter(sum_backscatter)
