The pressure sensor was recalibrated this week at the Boise Airport. The National Weather Service reports the air pressure hourly and converts it to sea level pressure for aircraft. I did not make an adjustment for the local temperature, so I will need to recalibration again some time. Afterwards, I will investigate how temperature affects the readings from the pressure sensor I'm using.
UAVSonde data were collected at 11:00 AM. Here are the data.
Altitude: 2,303 feet
Temperature: 40 *F
Relative Humidity: too cold to measure
Pressure: 929.5 mb
Altitude: 2,621 feet
Temperature: 36 *F
Relative Humidity: too cold to measure
Pressure: 916.9 mb
