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)
