Introduction
This Python module/script computes total atmospheric extinction from decomposition into physical components (Rayleigh attenuation, ozone absorption, aerosol extinction), as described in Buton et al. (2013), Atmospheric extinction properties above Mauna Kea from the Nearby Supernova Factory spectro-photometric data set.
Installation
The module is installable from pypi (traditional dependencies: numpy, scipy, matplotlib, astropy):
pip install pyextinctionExtinction parameters
Default extinction parameters are adapted to mean Mauna-Kea summit conditions:
Parameter |
Value ± Error |
|---|---|
Mauna Kea |
|
Pressure |
616 ± 2 mbar |
Ozone column |
257 ± 23 DU |
Aerosols optical depth @ 1 µm |
0.0076 ± 0.0014 |
Aerosols angstrom exponent |
1.26 ± 1.33 |
Please contact us if you have derived mean extinction parameters for other locations.
