This graph shows a 24 hour history of dry-bulb air temperature. The vertical axis is auto-scaled to accommodate the maximum and minimum values recorded during the period. Twenty four hours of time are shown on the horizontal axis with M indicating midnight. The sensor is convection cooled and shielded from solar radiation. Temperature resolution is appproximately one degree Fahrenheit.
This graph shows a 24 hour history of dew point temperature. Dew point temperature is calculated from the measured relative humidity, dry bulb temperature and barometric pressure. Temperature resolution is approximately one degree Fahrenheit. Twenty four hours of time is shown on the horizontal axis with M indicating midnight.
