ARC-ACTRIS

ARC-ACTRIS is a Python package implementing the Algorithm for Rayleigh and Raman Calculations.

It calculates molecular scattering and backscattering cross sections, Raman line contributions, and molecular linear depolarization ratios for atmospheric lidar applications.

Main features

• Rayleigh and Raman scattering calculations
• Molecular backscattering cross sections
• Molecular linear depolarization ratio, MLDR
• Dry and moist air mixtures
• Rotational Raman and vibrational Raman modes
• Optional interference filter transmission handling

Quick example

from arc_actris import arc

rrb = arc(
    incident_wavelength=355,
    backscattering=True,
)

cross_section = rrb.cross_section(cross_section_type="full")
mldr = rrb.mldr(mldr_type="full")

print(cross_section)
print(mldr)
