suntools: calculate sun position, sunrise, sunset, solar noon and twilight
Description
Provides a set of convenient functions for calculating sun-related information, including the sun's position (elevation and azimuth), and the times of sunrise, sunset, solar noon, and twilight for any given geographical location on Earth. These calculations are based on equations provided by the National Oceanic & Atmospheric Administration (NOAA) https://gml.noaa.gov/grad/solcalc/calcdetails.html as described in "Astronomical Algorithms" by Jean Meeus (1991, ISBN: 978-0-943396-35-4). A helpful resource for researchers and professionals working in fields such as climatology, biology, and renewable energy.
Details
suntools provides functions for calculating the sun's position, sunrise, sunset, solar noon, and crepuscular (twilight) times for any given geographical location and time on earth.
Main package functions:
-
crepuscule()
: Calculates crepuscular (twilight) times, i.e. the time of dawn or dusk. -
sunriset()
: Calculates the times of sunrise and sunset at a given location. -
solarpos()
: Calculates the solar position (elevation and azimuth) at a given location and time. -
solarnoon()
: Calculates solar noon time at a given location.
