SunCalcMeeus 0.1.2 (2025-01-09)
- 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 (2024-12-11)
- 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.
