OLI/MET/M1 - Intermittent wind data loss
DataStreams:olimetM1.b1
Description:
Occasionally the wind speed data are missing and wind direction data drop to 0 due to an 
ongoing sensor circuitry problem. Only invalid data are missing.
Measurements:olimetM1.b1:
  • wdir_vec_std
  • Wind speed vector mean(wspd_vec_mean)
  • Wind speed, lower, 1-min avg(wspd_arith_mean)
  • Wind direction vector mean(wdir_vec_mean)

OLI/DL/DLPROF/M1 - Reprocess: Incorrect serial number
DataStreams:olidlfptM1.b1
Description:
The instrument serial number that appears in the netcdf files global attributes is 
incorrect. The correct serial number is 0514-83.

OLI/DL/M1 - Instrument swap
DataStreams:olidlfptM1.b1
Description:
No data were acquired during this period because the instrument was in the process of 
being swapped out. Prior to 2016-05-12, the Oliktok Doppler lidar was a Halo Photonics 
StreamLine (S/N 0514-83). This was replaced with a Halo Photonics StreamLinePro (S/N 0116-109).
Measurements:olidlfptM1.b1:
  • range
  • East longitude(lon)
  • time_offset
  • intensity
  • elevation
  • Altitude above mean sea level(alt)
  • North latitude(lat)
  • azimuth
  • qc_radial_velocity
  • time
  • qc_time
  • Attenuated backscatter(attenuated_backscatter)
  • base_time
  • Radial velocity(radial_velocity)
