Present Weather An Optical Scientific Inc. OWI-130 Weather Identifier and Visibility Sensor. The "present weather" information is returned in WMO WX coded format for the highest present weather code during the past 60 seconds. |

Present Weather 15min An Optical Scientific Inc. OWI-130 Weather Identifier and Visibility Sensor. The "present weather" information is returned in WMO WX coded format for the highest present weather code during the past 15 minutes. |
|
|
Present Weather 60min An Optical Scientific Inc. OWI-130 Weather Identifier and Visibility Sensor. The "present weather" information is returned in WMO WX coded format for the highest present weather code during the past 60 minutes. |

Present Weather Visibility Tops out at 3100m (10000ft). Early data may be limited to 1100m. The visibility from the Belfort instrument ("Visibility") is recommended instead of this value |

Cloud Base 1 Cloud base, lower level, measured with a Mesotech Ceilometer model CBME40. The value will be zero if there's no return sigal, meaning there's either no clouds for the instrument to measure (clear sky) or there's no sharply defined return signal because of fog or precipitation. This device has a long data accumulation interval and occasionally does not produce a result in time for the weather system's minute by minute data archival; when a value is not received from the ceilometer, a default value of -1000000 is used. If the instrument is broken a small negative value will be shown for all cloud base and vertical visibility. |

Cloud Base 2 Cloud base, middle level, measured with a Mesotech Ceilometer model CBME40. The value will be zero if there's no return sigal, meaning there's either no clouds for the instrument to measure (clear sky) or there's no sharply defined return signal because of fog or precipitation. This device has a long data accumulation interval and occasionally does not produce a result in time for the weather system's minute by minute data archival; when a value is not received from the ceilometer, a default value of -1000000 is used. If the instrument is broken a small negative value will be shown for all cloud base and vertical visibility. |

Cloud Base 3 Cloud base, upper level, measured with a Mesotech Ceilometer model CBME40. The value will be zero if there's no return sigal, meaning there's either no clouds for the instrument to measure (clear sky) or there's no sharply defined return signal because of fog or precipitation. This device has a long data accumulation interval and occasionally does not produce a result in time for the weather system's minute by minute data archival; when a value is not received from the ceilometer, a default value of -1000000 is used. If the instrument is broken a small negative value will be shown for all cloud base and vertical visibility. |

|
Vertical Visibility Measured with the CBME40. Typically zero if any cloud base height is returned. |

BIT bit-level error code (hex) - If there are no errors this value should be zero. Error codes are additive; i.e., code 0300 would correspond to both a possible wind speed error (0100) and wind vane error (0200). |
