本文版本:通用预报接口/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/hourly.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/hourly.json

https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/hourly.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/121.6544,25.1552/hourly.json?lang=en_US&unit=metric&tzshift=14400&?hourlysteps=2
语言选项 lang:(简体中文(zh_CN)、繁体中文(zh_TW)、美式英语(en_US)、英式英语(en_GB))
经纬度附近地址中英文名称:getplacename=True
单位制选项 unit:(科学单位体系(SI) 、公制(metric)、英制(imperial))、(降水单位:mm/h)
时区偏移秒数:tzshift:(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)
定制返回预报总小时数:hourlysteps:(例如:未来360小时,未来2小时)
定制返回变量列表:fields=tmp,vis 【'ast', 'rad', 'prc', 'tmp', 'wnd', 'hmd', 'cld', 'aqi', 'pm25', 'pm25w', 'sky', 'skyh', 'lfi', 'alr', 'pres', 'vis', 'dswrf'】

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...
