Daily, Weekly, and Monthly Historical Cloud Sensor Data
The present time is on the left of the graph and the past is towards the right. The green bar graph indicates the sky condition (solid green is GOOD!): 60=CLEAR, 45=CLOUDY, 30=VERYCLOUDY, 15=WET (rain/snow), and 0=ERROR or DATA NOT AVAILABLE. The blue line indicates the difference between the air and sky temperatures (with the sign removed). Higher numbers mean clear skies, lower numbers mean clouds. Note that the sensor is quite "blind" to high thin clouds. When the sensor is wet, the blue line is set to 0, since the sensor reading is meaningless. The data originates from a Boltwood Cloud Sensor plus some custom programs and scripts running on the observatory PC and a Solaris Unix box.
