getObsAtmo

Python package to emulate atmospheric transparency simulation for different observation sites.

Transmission profiles depending on wavelength and airmass for Rayleigh scattering and atmospheric components absorption like Oxygen, water vapor or Ozon were extracted from libradtran. Those transmission profiles are located in obsatmo_data. In addition to libradtran interpolated gridded profiles, an analytic expression scattering for single component aerosol scattering is provided.

Example

from getObsAtmo.getObsAtmo import ObsAtmo

emul = ObsAtmo(obs_str = "LSST", pressure = 743.0)
wl = [400.,800.,900.]
am=1.2
pwv =4.0
oz=300.
transm = emul.GetAllTransparencies(wl,am,pwv,oz) # get transmission
print("wavelengths (nm) \t = ",wl)
print("transmissions    \t = ",transm)

emul.plot_transmission()  # plot the transmission
