Python 通过带obspy的fdsn访问地震记录数据（使用网络、台站、位置、通道）

我想下载vulcano Tungurahua周围地区的地震数据。在功能的obspy文档中，介绍了下载数据的步骤：

from obspy import UTCDateTime
t = UTCDateTime("2010-02-27T06:45:00.000")
st = client.get_waveforms("IU", "ANMO", "00", "LHZ", t, t + 60 * 60)
st.plot()  

这里get_waveforms方法具有参数

• 网络=“IU”
• station=“ANMO”
• 位置=“00”
• channel=“LHZ”

通过该功能，我找到了我案例中感兴趣的网络和站点名称：

• network=“YO”
• station=“TBAG”

但是，我不知道传递给函数“获取波形”所需的位置/通道字符串

---

我所尝试的：

client.get_stations(network="YO", station="TBAG")

返回：

Inventory created at 2017-04-23T18:27:16.000000Z
    Created by: IRIS WEB SERVICE: fdsnws-station | version: 1.1.25

    Sending institution: IRIS-DMC (IRIS-DMC)
    Contains:
        Networks (1):
            YO
        Stations (1):
            YO.TBAG (Banos, Tungurahua, Ecuador)
        Channels (0):

因此，似乎没有渠道存在。但是在尝试的时候

client.get_stations(network="IU", station="ANMO")

我明白了

因此，尽管频道“LHZ”明显存在，但此处并未列出它。

您需要使用

级别

参数：

client.get_stations(network="YO", station="TBAG", level="channel")

然后你应该得到：

        Contains:

                        YO.TBAG (Banos, Tungurahua, Ecuador)
                Channels (5):
                        YO.TBAG..HDF, YO.TBAG..HHZ, YO.TBAG..HHN, YO.TBAG..HHE, 
                        YO.TBAG..LOG

此参数如中所述：

level (str)
    Specify the level of detail for the results (“network”, “station”, “channel”,
    “response”), e.g. specify “response” to get full information including
    instrument response for each channel.
