PVC/MET/M1 - Tower lowered
DataStreams:pvcmetM1.b1
Description:
The tower containing the wind sensor was not at full-height of 10 meters following 
Hurricane Sandy.

PVC/GNDRAD/M1 - IRT failure
DataStreams:pvcgndrad20sM1.a0, pvcgndrad60sM1.b1
Description:
The IRT failed but continued producing a misleading analog signal. The ground surface 
temperature measurements were unrepresentative of the actual temperature.
Measurements:pvcgndrad60sM1.b1:
  • Surface Infra-Red Temperature Minima(sfc_ir_temp_min)
  • Surface Infra-Red Temperature Maxima(sfc_ir_temp_max)
  • sfc_ir_temp_std

PVC/MET/M1 - Instrument problem
DataStreams:pvcmetM1.00, pvcmetM1.b1
Description:
Present weather detector was occasionally reporting a hardware problem during this time. 
The reported error did not affect visibility readings, but caused all other data to report 
as missing. Error resolved its self with no indication of the problem cause.
Measurements:pvcmetM1.b1:
  • pwd_cumul_snow
  • pwd_pw_code_1_hr
  • pwd_avg_H2O_int_1_min
  • pwd_pw_code_inst
  • pwd_pw_code_15_min
  • pwd_cumul_water
pvcmetM1.00:
  • Raw data stream - documentation not supported
