Kyoto Dst

The routines in this module can be used to load Kyoto Dst data from the World Data Center for Geomagnetism, Kyoto.

Load the data

pyspedas.kyoto.dst(trange=None, time_clip=True, remote_data_dir='http://wdc.kugi.kyoto-u.ac.jp/', suffix='')

Loads Dst index data from the Kyoto servers.

Parameters:
  • trange (list of str, required) – Time range of interest with the format [‘YYYY-MM-DD’,’YYYY-MM-DD’] or to specify more or less than a day [‘YYYY-MM-DD/hh:mm:ss’,’YYYY-MM-DD/hh:mm:ss’].

  • time_clip (bool, optional) – Time clip the variables to exactly the range specified in the trange keyword. Defaults to True.

  • remote_data_dir (str, optional) – The remote directory from where to load the Dst index data. Defaults to “http://wdc.kugi.kyoto-u.ac.jp/”.

  • suffix (str, optional) – The tplot variable names will be given this suffix. By default, no suffix is added.

Returns:

List of tplot variables created.

Return type:

list

Examples

>>> from pyspedas.kyoto import dst
>>> dst_data = dst(trange=['2015-01-01', '2015-01-02'])
>>> print(dst_data)
kyoto_dst

Acknowledgment

The DST data are provided by the World Data Center for Geomagnetism, Kyoto, and are not for redistribution (http://wdc.kugi.kyoto-u.ac.jp/). Furthermore, we thank the geomagnetic observatories (Kakioka [JMA], Honolulu and San Juan [USGS], Hermanus [RSA], Alibag [IIG]), NiCT, INTERMAGNET, and many others for their cooperation to make the Dst index available.

Example

import pyspedas
from pytplot import tplot
dst_vars = pyspedas.kyoto.dst(trange=['2018-11-5', '2018-11-6'])
tplot('kyoto_dst')
