Construct a WEA from hourly data collections and the Zhang-Huang Solar Model.

## Inputs

* **location \[Required]**

  A Ladybug Location object. 
* **cloud\_cover \[Required]**

  Hourly DataCollection with the fraction of total sky cover (tenths of coverage). (eg. 1 is 1/10 covered. 10 is total coverage) 
* **rel\_humidity \[Required]**

  Hourly DataCollection with relative humidity \[%]. 
* **dry\_bulb\_temp \[Required]**

  Hourly DataCollection with dry bulb temperature \[C]. 
* **wind\_speed \[Required]**

  Hourly DataCollection with wind speed \[m/s]. 
* **atmos\_pressure**

  Hourly DataCollection with amtospheric pressure \[Pa]. If no value is connected here, pressure at sea level will be assumed (101,325 Pa). 

## Outputs

* **wea**

  A wea object from the input data collections and the Zhang-Huang solar model.
