囊括整个大中华地区的空气质量数据,收集了上百个环保局空气质量发布网站的2700多个监测点的数据。
 1.数据权威,均为官方环保局发布数据。 
2.覆盖范围广,整个大中华地区都覆盖,大陆,香港,澳门,台湾。
 3.站点密度高,除了国控外,还包括各个省市自建空气质量监测站点。
 4.对各级监测站的级别(国控,省控,地市控)进行了细分,可以根据需要调用。
 5.可以按地市一次性批量返回所有数据,便于显示。 
6.对于很多省市网站不提供经纬度的情况,上海青悦自行补充了所有站点的经纬度信息。 
7.自带经纬度信息,可以直接于GIS系统集成。
8.无数据(返回码441)或者无效数据(实时报超过2个小时 返回码:442)时不扣费。 
9.数据及时:国控,省控在官方发布后10分钟内更新数据,地市控,港澳台在官方发布后20分钟内更新数据。

1。输入城市名称。

2。返回该城市所有监测点数据。

具体输入参数和返回结果格式,请参考示例。
