Create an illustration of the layout of a meteorological observation field. The design should carefully consider the placement of various weather observation instruments to ensure the accuracy and comprehensiveness of the observed data. The meteorological tower, measuring 30m in height, should be situated in center with various instruments installed at different heights. At the top of the tower, place an anemometer for measuring wind speed and direction. Thermometers and hygrometers are scattered at different heights on the tower to obtain vertical temperature and humidity distribution. A rain gauge should be installed on the ground, distant from any structures or trees. Near the tower, place a barometer which should not be affected by building interference. A radiometer is installed on an open ground with no obstructions. Lightning detectors are placed around the observation field for all-direction monitoring. The data center is located in one corner of the field, responsible for data processing and storage.
