ATF Site: Yesterday Weather Conditions

The parameters being displayed are the following:

• Air Temperature [Celcius Degrees]
• Dew Point [Celcius Degrees]
• Relative humidity (computed out of the air temperature and dew point temperature)
• Barometric Pressure [mbar]
• Wind Direction [degrees from north, measured clockwise]
• Wind Speed [m/s]
• E-W and N-S Wind Components (shows prevailing winds)
• Solar Flux [W/m2]
• Temperature inside the Hoffman Box [Celcius Degrees]
• Hygrometer Status Flag (solid line)
  • 0 = Mirror Temperature not D/F Point Temperature: Mirror needs service
  • 1 = D/F Point Temperature: Normal Operations
  • 2 = Balancing...
  • 3 = Mirror is dirty needs service
  • 4 = D/F Point temperature and Mirror has some slight impurities: Will need service soon
  • 5 = Balancing and Mirror with some slight impurities: Will need service soon
  • 9 = No communication. Some problems with the PC-Hygrometer link, or CR4 turned OFF.
