HydPy-Meteo-Temp-IO (external temperature data)

Use meteo_temp_io as a submodel tp supply (relative) main models like evap_pet_hbv96 with externally available temperature time series.

Integration tests

Note

When new to HydPy, consider reading section Integration Tests first.

The only functionality of meteo_temp_io besides reading input time series is to adjust the given values to multiple hydrological response units. Hence, configuring and testing it does not require additional explanations:

>>> from hydpy.models.meteo_temp_io import *
>>> parameterstep()
>>> from hydpy import Element
>>> element = Element("element")
>>> element.model = model

>>> from hydpy import IntegrationTest, pub
>>> pub.timegrids = "2000-01-01", "2000-01-03", "1d"
>>> nmbhru(2)
>>> hruarea(0.2, 0.8)
>>> temperatureaddend(-0.6, -1.2)

>>> parameters.update()
>>> test = IntegrationTest(element)
>>> test.dateformat = "%Y-%d-%m"

>>> inputs.temperature.series = 2.0, 4.0

>>> test()

class hydpy.models.meteo_temp_io.Model

Bases: Sub_BaseModel, TempModel_V2

HydPy-Meteo-Temp-IO (external temperature data).

The following “run methods” are called in the given sequence during each simulation step:

• Calc_Temperature_V1 Take the input temperature for each hydrological response unit.

• Adjust_Temperature_V1 Adjust the previously determined temperature values.

• Calc_MeanTemperature_V1 Calculate the average temperature.

The following interface methods are available to main models using the defined model as a submodel:

• Determine_Temperature_V1 Interface method that applies the complete application model by executing all “run methods”.

• Get_Temperature_V1 Get the current temperature from the selected hydrological response unit.

• Get_MeanTemperature_V1 Get the mean temperature.
