Earth & Weather
Earth & Weather splits into Geography & Navigation, covering coordinate math and distance calculations, and Climate & Atmosphere, covering weather and air-quality measures like heat index and dew point. Both subcategories draw on published geodesy and meteorology formulas.
Categories in Earth & Weather
Climate & Atmosphere
Heat index, wet bulb temperature, dew point, humidity, cloud base altitude, and air quality index are calculated using the specific meteorological formula published by bodies like the National Weather Service, not a simplified rule of thumb.
Geography & Navigation
Distance between two latitude and longitude points, great-circle routing, GPS coordinate format conversion, bearing and azimuth, and finding a location's antipode: coordinate geography built on the spherical-geometry formulas used in aviation and marine navigation.
