Functions for calculations related to the atmosphere of the earth.

airmass clj/s

(airmass zenital-distance)

Calculates the increase factor of the air mass of the atmosphere depending on the zenital distance of the source.

airmass-simplified clj/s

(airmass-simplified zenital-distance)

Calculates the increase factor of the air mass of the atmosphere depending on the zenital distance of the source. The simplified formula may be used for zenital distances < 70°.

extinction clj/s

(extinction zenital-distance)

(extinction zenital-distance wave-length)

Calculates the athmospheric extinction of an object in a given zenital distance.

mie-extinction clj/s

(mie-extinction wave-length)

(mie-extinction wave-length condition)

Calculates the extinction by mie scattering in magnitudes.

rayleigh-extinction clj/s

(rayleigh-extinction wave-length)

(rayleigh-extinction zenital-distance wave-length)

Calculates the extinction by rayleigh scattering in magnitudes.

rayleigh-optical-depth clj/s

(rayleigh-optical-depth wave-length)

(rayleigh-optical-depth zenital-distance wave-length)

Calculates the optical depth (tau) of the rayleigh scattering.

refraction-by-apparent-altitude clj/s

(refraction-by-apparent-altitude altitude)

(refraction-by-apparent-altitude altitude temperature pressure)

Calculates the athmospheric refraction for an object at a given apparent altitude.

refraction-by-true-altitude clj/s

(refraction-by-true-altitude altitude)

(refraction-by-true-altitude altitude temperature pressure)

Calculates the athmospheric refraction for an object at a given true altitude.

temperature-pressure-correction clj/s

(temperature-pressure-correction temperature pressure)

Calculates the correction for temperature and air pressure
