Insolation for Palaeoclimate Studies
Annual Mean insolation
Compute astronomical parameters in the past or in the future
Caloric insolation
Converts calendar day into true solar longitude and vice-versa
Computes incoming solar radiation (insolation)
Time-integrated insolation

Integrated insolation for all days exceeding a threshold
R package to compute Incoming Solar Radiation (insolation) for palaeoclimate studies. Features three solutions: Berger (1978), Berger and Loutre (1991) and Laskar et al. (2004). Computes daily-mean, season-averaged and annual means and for all latitudes, and polar night dates.
