gfz-api-client 0.1.0

GFZ Helmholtz Centre for Geosciences Web Service API Client

GFZ Helmholtz Centre for Geosciences Web Service API Client

Description

Unofficial client for Helmholtz Centre for Geosciences Web Service API. For getting Geomagnetic Index (Kp, etc) Nowcast and Forecast data (https://spaceweather.gfz-potsdam.de/products-data/forecasts/forecast-kp-index). Kp is an important measure for the energy input from the solar wind to Earth and it is used by space weather services in near real-time. The geomagnetic Hpo index is a Kp-like index with a time resolution of half an hour, called Hp30, and one hour, called Hp60.

Official API description : https://kp.gfz-potsdam.de/en/data

Python 3.10+ requires

Features

• Getting geomagnetic index forecast (as a Dict)
• Getting geomagnetic three-hourly index for period (as a Dict)
• Getting geomagnetic three-hourly index for period as a Tuple (like an official client by GFZ German Research Centre for Geosciences)

Classes

Library provides Classic and Asynchronous client classes for using in python applications:

GFZClient - Classic client class for Web Service API

GFZAsyncClient - Asynchronous client class for Web Service API

Methods

get_forecast(index)

Returns Dict with Index prediction dataset. Parameter index define index for data request. Should be in ('Kp','Hp30', 'Hp30')

get_nowcast(start_time, end_time, index, [data_state])

Returns Dict with geomagnetic three-hourly Index for period. Parameters start_time and end_time defines time period. Both should be string with UTC date/time, format: 'YYYY-MM-DD' or 'YYYY-MM-DDThh:mm:ss' Parameter index define index for data request. Should be in ('Kp', 'ap', 'Ap', 'Cp', 'C9', 'Hp30', 'Hp60', 'ap30', 'ap60', 'SN', 'Fobs', 'Fadj') Optional Parameter data_state define index state. Possible values: 'def', 'all'. Output of definitive values only (only for Kp, ap, Ap, Cp, C9, SN)

get_kp_index(starttime, endtime, index, [status])

Returns tuple with geomagnetic three-hourly Index for period or (0, 0, 0) in an Error case. Parameters starttime and endtime defines time period. Both should be string with UTC date/time, format: 'YYYY-MM-DD' or 'YYYY-MM-DDThh:mm:ss' Parameter index define index for data request. Should be in ('Kp', 'ap', 'Ap', 'Cp', 'C9', 'Hp30', 'Hp60', 'ap30', 'ap60', 'SN', 'Fobs', 'Fadj') Optional Parameter status define index state. Possible values: 'def', 'all'. Output of definitive values only (only for Kp, ap, Ap, Cp, C9, SN)

Method get_kp_index implements getKpindex method from official python client with same behaviour and added for compatibility purposes

How to use

Installation

pip install gfz-api-client

Classic client

from gfz_client import GFZClient

client = GFZClient()

# Get geomagnetic index forecast
data = client.get_forecast(index="Kp")

# Get geomagnetic three-hourly Kp index for period
data = client.get_nowcast(start_time="2011-11-04T00:05:23", end_time="2011-11-04T00:05:23", index="Kp")

# Get geomagnetic three-hourly Kp index for period as a tuple
data = client.get_kp_index(starttime="2011-11-04T00:05:23Z", endtime="2011-11-04T00:05:23Z", index="Kp")

Asynchronous client

from gfz_client import GFZAsyncClient

client = GFZAsyncClient()

# Get geomagnetic index forecast
data = await client.get_forecast(index="Kp")

# Get geomagnetic three-hourly Kp index for period
data = await client.get_nowcast(start_time="2011-11-04T00:05:23Z", end_time="2011-11-04T00:05:23Z", index="Kp")

# Get geomagnetic three-hourly Kp index for period as a tuple
data = await client.get_kp_index(starttime="2011-11-04T00:05:23", endtime="2011-11-04T00:05:23", index="Kp")
