Working range of meteorological detector

High-altitude meteorological observation mainly measures the temperature, humidity, air pressure, wind direction and wind speed at various heights of the atmosphere, as well as other special items, such as atmospheric composition, ozone and radiation. 1, according to the above detection items, so the detector must reach the measured height before it can be carried out. It depends on what is being measured. The measurement of temperature, humidity, air pressure, wind direction and wind speed depends on which height is measured, and there is nothing to say. If it is meteorological measurement, it can be 500 meters to 800 meters near the ground. For example, ozone needs to reach the height of the ozone layer, that is, the atmosphere where ozone is relatively concentrated 10 ~ 50 km (the highest concentration is 20 ~ 25 km). So, it depends on what the test item is. 2. As the height of the balloon increases, the atmospheric pressure becomes smaller and smaller, and the hydrogen inside will make the balloon bigger and bigger. When the balloon reaches a certain height, its buoyancy is as great as gravity, so it won't rise again. In this process, if the balloon is of poor quality, it will explode. If the quality is good and can withstand it, then the balloon will only get bigger and will not explode. This height is determined by the weight of the balloon. In fact, this height is not easy to find, because the density of the atmosphere will change at different latitudes and different times (day and night). So these two factors determine that this question is not easy to answer. But generally speaking, balloon detection is only used for low-altitude detection, and high-altitude ozone detection requires satellites, such as backscattered ultraviolet spectrometer (BUV) and infrared interference spectrometer (IRIS).
