How can the new generation of automatic weather stations guarantee data integrity?

The new generation of automatic weather stations is a new way of meteorological observation, which is important for disaster prevention and mitigation and forecasting and early warning. There are many automatic weather stations in China, but the problem of abnormal or lost data can occur in their use. In order to guarantee the accuracy and integrity of the data, we need to consider a variety of factors such as equipment, human and environment.

1, Environmental factors

The electronic components of automatic weather stations are very sensitive and easily affected by the environment, resulting in poor data quality. Urban development has caused some weather stations to move, which affects the integrity and continuity of the data. Thunder and lightning and other weather will also make the performance of the weather station decline, or even damage, so that the data is not allowed.

2, hardware failure

The hardware equipment of the automatic weather station must be well selected in order to carry out normal weather monitoring. If the equipment fails, the monitoring will be affected, and can not achieve the desired results.

2, calibration problems

The performance of automatic weather station will decline after working for a long time, and the sensor may not be accurate. So it is important to test and calibrate them regularly to ensure that each weather station is accurate. If the hardware is aging, it has to be replaced in time. In this way, the weather station can maintain the best monitoring quality.

3, Equipment Maintenance

If the staff doesn't maintain the equipment of the weather station regularly, the data quality will be affected. Especially after heavy rainfall, the sensors are prone to soil and dust, which affects the ground temperature observation. The rainfall sensor may also be blocked by debris, resulting in inaccurate rainfall data. Therefore, observers have to maintain the equipment frequently to ensure data quality.

The above four points are the keys that affect the monitoring of automatic weather stations. Selection of equipment should be appropriate, regular testing, inspection and calibration. It is also important to choose the address of the weather station, preferably in a place without interference. This will ensure that the weather station monitoring is accurate and complete.
