metobs_toolkit.Dataset.add_new_observationtype#

Dataset.add_new_observationtype(Obstype)[source]#

Add a new observation type to the known observation types.

The observation can only be added if it is not already present in the knonw observation types. If that is the case that you probably need to use use the Dataset.add_new_unit() method.

Parameters:: add. (The new Obstype to)
Return type:: None.

Examples

>>> import metobs_toolkit
>>> co2_concentration = metobs_toolkit.Obstype(obsname='co2',
...                                            std_unit='ppm')
>>> #add other units to it (if needed)
>>> co2_concentration.add_unit(unit_name='ppb',
...                            conversion=['x / 1000'], #1 ppb = 0.001 ppm
...                           )
>>> #Set a description
>>> co2_concentration.set_description(desc='The CO2 concentration measured at 2m above surface')
>>> #Add it to a Dataset
>>> dataset = metobs_toolkit.Dataset()
>>> dataset.add_new_observationtype(co2_concentration)
>>> dataset.obstypes
