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.

CRAN release: 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()
andrelative_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.
