SunCalcMeeus 0.1.2
- Add function
irrad_extraterrestrial() implementing
estimation of the (shortwave) energy irradiance at the top of the
atmosphere above a specific geographic location and at a given instant
in time. The irradiance is estimated on a plane tangential to the
surface of the “sphere” or Earth globe. Thus, it returns the solar
constant corrected for the angle of incidence and for the current
Earth-Sun distance.
- Add on-line only article with accuracy and performance tests based
on comparisons to alternatives.
SunCalcMeeus 0.1.1
- Add function
relative_AMt() implementing Young’s (1994)
AM approximation based on the true position of the sun.
- Add
relative_AM_geotime() and
relative_AMt_geotime()as convenience wrapper
functions.
- Increase test coverage to nearly 95% with new tests and fix some
minor bugs.
- Fix bug in
distance_to_sun(), the value returned was
totally off-mark.
SunCalcMeeus 0.1.0
- Package created as a spin-off from ‘photobiology’ by moving the
astronomical computations related to the sun position, unchanged.
