%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
resource for researchers and professionals working in fields such as
climatology, biology, and renewable energy.
