免费气象数据获取_免费气象数据

1.哪里有气象数据下载（主要是湿度、温度、风速、降雨量、云量等）。 谢谢!

2.国内有哪些城市较完整可以免费使用的天气 API 接口

除了国家气象局还有很多气象数据平台，可以查询各地区的历史气象数据。

数据来源：羲和能源大数据平台 (xihe-energy.com)

步骤一：羲和首页进行地理位置选择。可以选择全球任意位置单点数据也可以选择区域平均数据

步骤二：确认数据源。

步骤三：输入想查询下载的起止时间，可选历史40年和未来7日

步骤四：选择所需要的气象数据下载，导出csv格式小时级数据，保存数据可视化，也可根据需要选择API接口

步骤五：如需要查询更多数据，可在“更多属性”中进行“检索属性”

2、www.xihe-energy.com?羲和能源大数据平台

3、www.cdc.noaa.gov/public.data?中国气象局

4、www.edu.cn?中国教育科研计算机网

5、weather.com.cn/?中国天气网

步骤一：在羲和平台首页进行地理位置选择。既可以选择单点数据也可以选择区域平均数据

步骤二：确认数据源。历史数据可选择羲和数源、欧洲中期天气中心、美国国家航空航天局；预测数据可选择德国气象局

步骤三：输入想查询下载的起止时间，可选历史40年和未来7日

步骤四：选择所需要的气象数据下载，如降水等，导出小时级数据

步骤五：如需要查询更多数据，可在“更多属性”中进行“检索属性”

国内有哪些城市较完整可以免费使用的天气 API 接口

有很多地方都可以查询下载到多年的气象数据（气温、气压、湿度、降水量、风速、风向、辐射等等）

1.中国气象科普

2.羲和能源大数据

3.中国气象局

4.中国国家气候中心

5.?USGS Earth Explorer(美国地质调查局)

6.?NOAA CLASS(美国国家海洋和大气管理局)

7.ESA’s Sentinel Mission(欧洲航天局哨兵系列卫星)

步骤一：输入地理信息，自动给出经纬度及所在时区。

步骤二：输入想查询下载的起止时间和数据源。

步骤三：选择所需要的气象数据下载。

因微信公共号提供城市天气预报服务，发现网山天气预报接口和环境数据接口方面资料比较乱，而且有不少内容已经失效，下面内容由过程日志整理形成，希望可用得上。

一 天气预报

国内的天气预报数据，主要是国家气象局和国外两个来源（指数据来源）。

国外方面主要是雅虎（XML格式，谷歌已经停掉了自家的天气API）；

国内数据由国家气象局提供（JSON格式）。

在知乎看到过一篇专业人士评论，雅虎可以提供全球范围的且非常精细的天气数据（小时级更新），但主要是通过计算机自动生成。而国家气象局则是各地经验丰富的专家人士结合计算机综合分析得出，在准确性上更胜一筹。我就这样信了！

国家气象局接口资源及用法

气象局的天气预报主页：移动版普通版 ,仔细挖掘这两个地址可以发现很多好东西哦。

特点：接口多，来自weather.com.cn和mobile.weather.com.cn都有，次数不限制，服务稳定，功能全面，优先推荐。

1. 实时天气接口

有多个接口，好像差别不大：

实时天气1：实时天气2：实时天气3（带时间戳）： 一周天气预报接口

7天预报数据 URL： 该接口来源气象局移动版网站，目测数据最为精确，详细接口格式如下：

"f0":"201310121100"}}

详细接口分析如下：
