3.天气预报中的API:Excellent是啥意思
4.免费的天气预报Api有哪些
首先可以明确一点,所有的气象数据一定都是来自官方的,以非官方名义公布天气数据应该还没有人敢,只是国家天气数据也有不准的时候,所有的公司都面临一个问题,怎么样让自己的数据比竞品更准?1、国家天气数据为什么也会不准?
国家天气数据中的一部分是地面、高空、雷达观测数据,会自动汇总到国家气象信息中心通信台。
一部分是卫星数据,比如中国的风云卫星一般需要20多分钟才能完成全球扫描,所以这部分的数据通常有半小时左右的延迟。
最后是预报数据,气象学上有一些标准模型,跑模型的时间,数据打包传输分发的时间其实是比较长的(由于数据量的关系),比如气象局可能用欧洲中心模式系统的数据,有一些延迟,但是预报的特性就是随着时间不断接近,预测越是准确,很容易理解。就我所知,国家高校的一些研究机构也有自己的模型,也不敢说哪个就一定是最准的。
(一部分信息来自中国气象网)
2、国家天气数据可能是不全面的
有些时候我们想要通过手机传感器获得的经纬度来获取天气数据,或者通过?IP?地址来获取天气数据,这些都是很常见的需求,而国家天气数据的?API?可能不支持。
或者,地方气象台有一些地方的气象数据,它们属于省级气象数据,并不需要上报到国家级,那么自然国家天气数据的?API?不支持,但是地方依旧会公布它们。
亦或者,很多人关心 PM2.5,这些数据不是来自气象局,而是来自环保局,而且环保局还没有空气质量预报,又要从其他机构接入。
如何使用百度天气预报API接口
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.cn和://mobile.weather.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:://.weather.cn/data/sk/101190408.html
实时天气2:://.weather.cn/data/cityinfo/101190408.html
实时天气3(带时间戳):://mobile.weather.cn/data/sk/101010100.html?_=1381891661455
2. 一周天气预报接口
7天预报数据 URL: ://mobile.weather.cn/data/forecast/101010100.html?_=1381891660081
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:

package com.example.administrator.jsontest;
public class MainActivity extends Activity {
private Button button;
private TextView textView;
private Handler handler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 0:
String re = (String) msg.obj;
textView.setText(re);
break;
}
}
};
@Override
protected void onCreate(Bundle sedInstanceState) {
super.onCreate(sedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
textView = (TextView) findViewById(R.id.textView);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Log.i("T", "点击了Button");
sendRequestWithHttpClient();
}
});
}
private void sendRequestWithHttpClient() {
new Thread(new Runnable() {
@Override
public void run() {
HttpURLConnection connection = null;
try {
URL url = new URL("://api.map.baidu/telematics/v3/weather?location=南昌&output=json&ak=8ixCCFzlBB617YX7tONI2P5B&mcode=1C:6B:42:33:E8:A6:DC:A2:11:6E:26:EC:84:BD:42:E3:8E:6B:57:9A;com.example.administrator.jsontest");
connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("GET");
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);
InputStream in = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(in));

4.?运行结果如下:?
天气预报中的API:Excellent是啥意思
$.getScript('://int.dpool.sina.cn/iplookup/iplookup.php?format=js',?function(_result)?{
if?(remote_ip_info.ret?==?'1')?{
$.ajax({
type:?"GET",
url:?"://wthrcdn.etouch.cn/weather_mini?city="+remote_ip_info.city,
data:?"",
success:?function(msg){
console.log(msg);
}
});
}
});
免费的天气预报Api有哪些
API:Excellent 空气污染指数:良好
API:Air Pollution Index空气污染指数。API指数分级如下:0~50(I级)为良好;51~100(Ⅱ级)为一般;大气环境处于I、Ⅱ级时都可以正常活动;101~200(Ⅲ级)为不佳;201~300(Ⅳ级)为较差; API>300(V级)时为差。
上聚合数据、百度API上找啊,一般申请一个帐号,天气这种api都有送次数的
也有免费无次数的,如:://flash.weather.cn/wmaps/xml/chongqing.xml
求纳
