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:v2.2v2.3,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

返回结构和说明

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):

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...
