本文版本：逐分钟降水短临预报接口/v2.2，当前稳定版本版本：v2.5，历史版本：v2.2，v2.3，和 v2.4。

授权与认证

请先至彩云开放平台注册，注册后可以获得 token 。

把您的 token 拼到 API 请求的 URL 中，如

https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/minutely.json

其中 TAkhjf8d1nlSlspN 就是一个共用测试 token 。不要把私有token 告诉任何人！

请求样例

示例1如下

https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/minutely.json
https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/minutely.jsonp?callback=MYCALLBACK
token：这里是测试 token ，即 TAkhjf8d1nlSlspN
经纬度：经度在前，纬度在后，中间用半角逗号隔开，这里是 121.6544,25.1552
返回格式：json 或者 jsonp，jsonp 需提供回调函数名

示例2如下

https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/118.7087,26.9582/minutely?lang=en_US&getplacename=True
经纬度附近地址中英文名称 getplacename：True
语言选项 lang：默认为简体中文（zh_CN）、繁体中文（zh_TW）、美式英语（en_US）、英式英语（en_GB）
单位制选项 unit：默认为公制（metric）、科学单位体系（SI） 、英制（imperial）
时区偏移秒数：tzshift：默认为东八区，tzshift=28800；例如：印度东5.5区，tzshift=3600*5.5==19800，v2.3之后版本，返回时区信息，使用秒是为了支持像尼泊尔这样的差 5 小时 45 分钟的地区，它们有非整齐的偏移量

支持的单位制

1.目前支持的单位制包括：科学单位体系（SI，大写）、英制（imperial）、公制（不带参数&unit默认公制，公制还包括: metric:v1和metric:v2）:

单位制
要素
 SI（科学单位体系） imperial（英制） metric:v1（公制v1） metric:v2（公制v2） default metric(默认公制)
实况降水量 米/秒(meter/sec) 英寸/小时(in/hr) 雷达降水强度（0~1） 毫米/小时(mm/hr) 雷达降水强度（0~1）
逐分钟降水短临预报降水量 米/秒(meter/sec) 英寸/小时(in/hr) 雷达降水强度（0~1） 毫米/小时(mm/hr) 雷达降水强度（0~1）
逐小时预报降水量 米/秒(meter/sec) 英寸/小时(in/hr) 雷达降水强度（0~1） 毫米/小时(mm/hr) 毫米/小时(mm/hr)

unit=metric:v1时，所有类型中precipitation的单位都是：雷达降水强度（0~1）

unit=metric:v2时，所有类型中precipitation的单位都是：毫米/小时(mm/hr)

2.判断降水等级:

  • 带参数&unit=metric:v1，请求实况、分钟级、逐小时和逐日降水强度，单位都为雷达降水强度（0 ~ 1）；
  • 雷达降水强度（0 ~ 1）判断降水等级：0.03~0.25 小雨(雪)， 0.25~0.35 中雨(雪)， 0.35~0.48大雨(雪)， >0.48 暴雨(雪)；
  • v2.4版本中，本地存在降水时，可以根据skycon（存在于realtime、hourly、daily字段），和skycon_08h_20h和skycon_20h_32h（存在于daily字段），中的：LIGHT_RAIN, MODERATE_RAIN, HEAVY_RAIN, STORM_RAIN(LIGHT_SNOW, MODERATE_SNOW, HEAVY_SNOW，STORM_SNOW)直接获取降水等级
  • 大暴雨(雪)和特大暴雨(雪)，需要根据24小时累计公制降水量（mm/24hr）来判断，研发中...
