Subject: OLI/MET/M1 - Present weather detector backscatter warning
Affected Datastreams: olimetM1.b1
Description During this time, the present weather detector intermittently indicated a backscatter warning. A routine lens cleaning eliminated the backscatter. Data do not appear to be affected.

Subject: OLI/MET/M1 - Intermittent wind data loss
Affected 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
  • wspd_vec_mean (Wind speed vector mean)
  • wspd_arith_mean (Wind speed arithmetic mean)
  • wdir_vec_mean (Wind direction vector mean)
  • wdir_vec_std (Wind direction vector mean standard deviation)

Subject: OLI/MET/M1 - Wind data missing following generator maintenance
Affected Datastreams: olimetM1.b1
Description Following generator maintenance, the wind sensor stopped reporting wind data. Communication was reestablished following a configuration check.
Measurements
  • wspd_vec_mean (Wind speed vector mean)
  • wspd_arith_mean (Wind speed arithmetic mean)
  • wdir_vec_mean (Wind direction vector mean)
  • wdir_vec_std (Wind direction vector mean standard deviation)
