💖 DESCRIPTION 💖

okay so this is the solar topic, and it's giving main character energy for everyone who wants to compute things about our fave giant fireball 🔥 Here's the squad, no cap:

• r.horizon — computes the horizon angle height from a digital elevation model 👑 like, how tall is the skyline in every direction, elevation-model style.
• r.sun — solar irradiance and irradiation model 💅 the big one, fr fr.
• r.sunhours — calculates solar elevation, solar azimuth, and sun hours 🦋 so you know where the sun is and how long it's been hanging out.
• r.sunmask — calculates cast shadow areas from sun position and elevation raster map 🫶 shadow queen behaviour, honestly.
