pvlib.iotools.get_meteonorm_forecast_basic(latitude, longitude, start, end, api_key, parameters='all', *, surface_tilt=0, surface_azimuth=180, horizon='auto', interval_index=False, map_variables=True, url='https://api.meteonorm.com/v1/')[source]#

Retrieve basic forecast data from Meteonorm.

The basic forecast data only supports hourly time step.

The Meteonorm data options are described in [1] and the API is described in [2]. A detailed list of API options can be found in [3].

Parameters:
  • latitude (float) – In decimal degrees, north is positive (ISO 19115).

  • longitude (float) – In decimal degrees, east is positive (ISO 19115).

  • start (datetime like or str) – First timestamp of the requested period. If a timezone is not specified, UTC is assumed. Relative date/time strings are also allowed, e.g., ‘now’ or ‘+3hours’.

  • end (datetime like or str) – Last timestamp of the requested period. If a timezone is not specified, UTC is assumed. Relative date/time strings are also allowed, e.g., ‘now’ or ‘+3hours’.

  • api_key (str) – Meteonorm API key.

  • parameters (list or 'all', default : 'all') – List of parameters to request or ‘all’ to get all parameters.

  • surface_tilt (float, default : 0) – Tilt angle from horizontal plane.

  • surface_azimuth (float, default : 180) – Orientation (azimuth angle) of the (fixed) plane. Clockwise from north (north=0, east=90, south=180, west=270).

  • horizon (str or list, default : 'auto') – Specification of the horizon line. Can be either ‘flat’, ‘auto’, or a list of 360 integer horizon elevation angles.

  • interval_index (bool, default : False) – Index is pd.DatetimeIndex when False, and pd.IntervalIndex when True. This is an experimental feature which may be removed without warning.

  • map_variables (bool, default : True) – When true, renames columns of the Dataframe to pvlib variable names where applicable. See variable VARIABLE_MAP.

  • url (str, optional) – Base URL of the Meteonorm API. The default is pvlib.iotools.meteonorm.URL.

Raises:

requests.HTTPError – Raises an error when an incorrect request is made.

Returns:

  • data (pd.DataFrame) – Time series data. The index corresponds to the middle of the interval unless interval_index is set to True.

  • meta (dict) – Metadata.
