Subject:
TWP/VCEIL/C2 - Nauru Vceil data suspect
DataStreams:twpvceil25kC2.a1, twpvceil25kC2.b1
Description:
During this period the ceilometer began producing a cross-talk warning. Since it is a 
warning, some of the data are OK. However, the instrument began to be limited to detecting 
clouds only about 2 km above the ground.
Measurements:twpvceil25kC2.b1:
  • Aerosol backscatter coefficient at 355 nm(backscatter)
  • Flag indicating aeri retrieval status(status_flag)
  • Third cloud base height(third_cbh)
  • Lowest cloud base height detected.(first_cbh)
  • Warning and alarm status bits(status_string)
  • range(range)
  • Percentage of nominal factory setting (0 to 999%)(receiver_sensitivity)
  • Vertical visibility(vertical_visibility)
  • Altitude of highest signal(alt_highest_signal)
  • Second lowest cloud base height(second_cbh)
  • Backscatter sum(sum_backscatter)
twpvceil25kC2.a1:
  • Altitude of highest signal(alt_highest_signal)
  • Flag indicating aeri retrieval status(status_flag)
  • Backscatter sum(sum_backscatter)
  • range(range)
  • Warning and alarm status bits(status_string)
  • Percentage of nominal factory setting (0 to 999%)(receiver_sensitivity)
  • Vertical visibility(vertical_visibility)
  • Detection status. See details(detection_status)
  • Third cloud base height(third_cbh)
  • Aerosol backscatter coefficient at 355 nm(backscatter)
  • Second lowest cloud base height(second_cbh)
