Subject:
SGP/VCEIL/B4 - Receiver failure
DataStreams:sgpvceil25kB4.00, sgpvceil25kB4.a1, sgpvceil25kB4.b1
Description:
The receiver failed abruptly just a few minutes after 00:00 UTC on  Dec. 12, 2002.  The 
problem was resolved by replacement of the broken ceilometer with a working ceilometer on 
Jan. 10, three days after the problem was PIFed.
Measurements:sgpvceil25kB4.00:
  • null(Raw data stream - documentation not supported)
sgpvceil25kB4.a1:
  • range(range)
  • GPS raw data filename(filename)
  • Lowest cloud base height detected.(first_cbh)
  • Time offset of tweaks from base_time(time_offset)
  • Parameter scale(parameter_scale)
  • Warning and alarm status bits(status_string)
  • Dummy altitude for Zeb(alt)
  • Backscatter sum(sum_backscatter)
