class point_mode : public module_base#

Use this module to enable using CHM in point mode. This module does not to any spatial interpolation. Instead, it passes input met through to the per-triangle variables storages. This is suitable for using CHM like a point scale model, such as at a research site. Specifically this sets depends_from_met(...) inputs such that depends(...) in other modules can work.

Depends from met::

  • Air temp “t” [ \( {}^\circ C \)]

  • Relative humidity “rh” [%]

  • Wind speed “u” [ \( m \cdot s^{-1} \) ]

  • Precipitation “p” [mm]

  • Incoming longwave radiation “Qli” [ \( W \cdot m^{-2}\)]

  • Incoming shortwave radiation “Qsi” [ \( W \cdot m^{-2}\)]

  • Incomging shortwave radiation, diffuse beam “iswr_diffuse” [ \( W \cdot m^{-2}\)]

  • Incomging shortwave radiation, direct beam “iswr_direct” [ \( W \cdot m^{-2}\)]

  • Wind direction @2m “vw_dir” [degrees]

  • Ground temperature “T_g” [ \( {}^\circ C \)]

Provides:

  • Air temp “t” [ \( {}^\circ C \)]

  • Relative humidity “rh” [%]

  • Wind speed @2m “U_2m_above_srf” [ \( m \cdot s^{-1} \) ]

  • Wind speed @reference height “U_R” [ \( m \cdot s^{-1} \) ]

  • Precipitation “p” [mm]

  • Incoming longwave radiation “ilwr” [ \( W \cdot m^{-2}\)]

  • Incoming shortwave radiation “iswr” [ \( W \cdot m^{-2}\)]

  • Incomging shortwave radiation, diffuse beam “iswr_diffuse” [ \( W \cdot m^{-2}\)]

  • Incomging shortwave radiation, direct beam “iswr_direct” [ \( W \cdot m^{-2}\)]

  • Wind direction @2m “vw_dir” [degrees]

  • Ground temperature “T_g” [ \( {}^\circ C \)]

Configuration: 

 "provide":{
    "t": true,
    "rh": true,
    "U_R": true,
    "U_2m_above_srf": true,
    "p": true,
    "ilwr": true,
    "iswr": true,
    "vw_dir": true,
    "iswr_diffuse": false,
    "iswr_direct": false,
    "T_g": false,

    "override":
    {
       "svf":0.8
    }

}
override.svf#

Allows for setting the sky view factor at the point to be different than what was calculated from the mesh.

Note

The configuration allows for fine-tuning what is passed through. So although Depends from met below lists all of the possible depends, whatever is set in the configuration will be what is required at runtime.

Public Functions

point_mode(config_file cfg)#
~point_mode()#
virtual void run(mesh_elem &face)#

Needs to be implemented by each data parallel module. This will be called and executed for each timestep

Parameters:

  • face – The terrain element (triangle) to be worked upon for an element parallel domain

  • global_param – A pointer to the shared global paramter space with domain-wide paramters
