我无法找到好的来源来制作一个AQI(空气质量指数)
测量设备。我所能找到的只是不同地区的计算方法。但是我需要一些帮助,用于测量不同污染物浓度的技术,如<代码>江南登录网址app下载SO2, NOx, PM10, PM2.5等。代码>
关于用于测量AQI的技术有什么好的论文或专利吗?
感谢任何帮助。谢谢。< / p >
为了检测最常监测的污染物,你需要一个臭氧分析仪和PM2.5监测器。这太贵了。一个好的单一污染物监测仪将花费数千美元购买和许多后续成本。你还需要校准设备和标准。根据您将使用的AQI网络作为参考,您所使用的仪器型号必须满足某些规范,才能使数据有效。Teledyne是一家生产符合USA AirNOW网络条件的设备的公司的例子。你可能还会对他们的nice AQI计算器.
.The third approach is the banding system, which is more popular in European countries like the UK and France (websites 3, 13). The main deviation is that instead of using an index scale of 0 to 500, a scale of 0 to 10 is being used. For the UK system, this index scale of 10 is further broken down into four bands of ‘low’ (1-3), ‘moderate’ (4-6), ‘high’ (7-9) and ‘very high’ (10) (website 13). The key reference point for this banding system is the breakpoint value between the ‘low’ and ‘moderate’ bands. The lower bound of index value 4 is set to correspond to the UK Air Quality Standards for all pollutants but NO 3 2. In this case, the 1-hour national standard for NO2 is 200 g/m , whereas the lower bound of index value 4 for NO2 is 287 g/m3 (website 13).
