Rain Gauge Measurement Calibration Procedures

rain gauge calibration

After a recent rain event, I noticed that The Davis tipping bucket rain gauge was not reading correctly. For comparison purposes I have it mounted side by side with a standard 4″ manual gauge of known accuracy. The 4″ gauge registered 1.12″ of precipitation while the Davis gauge registered .88″ of rain. This is a significant difference for such a small amount of total rain. Continue reading

Rain Gauges

KI5OMM weather station

The rain gauge that I use for the KI5OMM weather station is a tipping bucket design. This allows for automatic and unattended operation. This type of rain gauge is fairly accurate for most rainfall events. They do have a few flaws that can lead to errors in reporting. For this reason, I also use a manual 4″ rain gauge for backup. Here is a description of my setup and design for my station. Continue reading

ki5omm weather station

After weeks of building, calibrating, and testing, the weather station at KI5OMM is finally ready to measure and record some permanent data for the climatological record at station KI5OMM. At 1100 UTC the station was put on line and began recording data for the permanent record. Why is this important? Continue reading

A detailed tour of the KI5OMM weather station.

The KI5OMM weather station is comprised of a blend of both new and old technology.

KI5OMM weather Station

The weather station at KI5OMM was constructed using weather sensors from Davis Instruments. Davis has been a leader in weather station technology for many years and their equipment is both durable and very accurate. Along side the Davis sensors are some backup measurement tools such as lab grade mercury glass thermometers. The thermometers are four basic types – wet bulb, dry bulb, maximum, and minimum. All of this equipment is housed in an instrument shelter known as a Cotton Region Shelter that provides a stable environment for temperature, dew point, and humidity measurements. Continue reading
