◆ is_anyptype_nonTotRan()

bool is_anyptype_nonTotRan ( const ArrayOfArrayOfSingleScatteringData scat_data_mono)

is_anyptype_nonTotRan.

Some operations in Monte Carlo simulations are different depending on the ptype of the scattering elements. This function searches scat_data to determine if any of the scattering elements have ptype=30.

mcPathTraceGeneral.

Performs the tasks of pathlength sampling.

Ray tracing done (but now only as far as determined by pathlength sampling) and calculation of the evolution operator and several atmospheric variables at the new point.

The end point of the ray tracing is returned by ppath_step, where the point of concern has index ppath_step.np-1. However, a somehwat dirty trick is used here to avoid copying of data. Only ppath.np is adjusted, and ppath_step can contain additional points (that should not be used).

[out]abs_vec_monoTotal monochromatic absorption vector.
[out]temperatureA vector of temperatures.
