emc2.simulator.lidar_moments.calc_lidar_bulk(instrument, model, is_conv, p_values, z_values, OD_from_sfc=True, hyd_types=None, mie_for_ice=False, **kwargs)

Calculates the lidar stratiform or convective backscatter, extinction, and optical depth in a sub-columns using bulk scattering LUTs assuming geometric scatterers (radiation scheme logic). Effective radii for each hydrometeor class must be provided (in model.ds).

Parameters:

instrument: Instrument

The instrument to simulate. The instrument must be a lidar.

model: Model

The model to generate the parameters for.

is_conv: bool

True if the cell is convective

p_values: ndarray

model output pressure array in Pa.

z_values: ndarray

model output height array in m.

OD_from_sfc: bool

If True, then calculate optical depth from the surface.

hyd_types: list or None

list of hydrometeor names to include in calcuation. using default Model subclass types if None.

mie_for_ice: bool

If True, using bulk mie caculation LUTs. Otherwise, currently using the bulk C6 scattering LUTs for 8-column severly roughned aggregate.

Additonal keyword arguments are passed into

:py:func:`emc2.simulator.lidar_moments.accumulate_OD`.

Returns:

model: emc2.core.Model()

The model with the added simulated lidar parameters.
