Examples showing libradtranpy module use

Examples in Visible mode (200 nm - 1200 nm)

Different modes of simulations

• single atmospheric tranparency simulation

• atmospheric transparency simulation versus airmass

• atmospheric transparency with clouds of different optical depth

• atmospheric transparency profiles for scattering processes

• atmospheric_transparency profile for absorption processes

Multisites simulations

• Comparison of total transmission at different sites

• Comparison of Rayleigh scattering at different sites

• Comparison of O2 absorption at different sites

Examples in Thermal mode

Impact of clouds

• Impact of clouds on sky brightness

• Impact of clouds on transmittance

• Impact of clouds on Irradiance

• Integrated irradiance vs cloud depth

• Impact of clouds on Radiance

Impact of precipitable water vapor

• Impact of PWV on sky brightness

• Impact of PWV on transmittance

• Impact of PWV on irradiance

• Integrated irradiance vs PWV

Examples showing the use of analytical models

This help to check the output of libradtran.

• atmospheric model altitude vs pressure or massdensity

• atmospehric model altitude vs pressure

Example of module pyextinction

Yannick Copin has implemented the python package pyExtinction.

https://gitlab.in2p3.fr/ycopin/pyExtinction/-/tree/master/pyExtinction

which is included here as a tool to check libradtran simulation.

• Simple test of pyextinction

• Compare libradtran simulation wrt pyextinction
