Why “isohel” is a great word
ISOHEL — [Noun] A cartographic line connecting points that receive identical amounts of solar radiation or equal daily hours of sunshine. From iso- (from Greek isos, meaning "equal") + -hel (from Ancient Greek hēlios, meaning "sun"). Unlike an isotherm, which charts the fickle gradient of temperature shaped by wind and sea, or an isohyet, which follows the melancholy geography of rain, an isohel traces a purer, celestial geometry—the stark ledger of light itself. It is the invisible frontier between a vineyard’s perfect ripening slope and its neighbor’s merely adequate terroir; the precise meridian where a solar panel’s output becomes viable; the cartographic seam stitching together a desert, a coast, and a city square within the same daily ration of gold. To follow an isohel is to trace a map of human fortune written in the silent currency of photons, a reminder that our most fundamental economies are drawn by the sun.
Etymology
From iso- + Ancient Greek ἥλιος (hḗlios, “sun”).
noun
- A line on a map connecting places that receive equal solar radiation, or equal daily hours of sunshine.e.g.“Each map shows a zone of increased sunshine between Ghana and Nigeria, destroying the regular pattern of east-west trending isohels across southern Nigeria and Ivory Coast.” — 1987, Derek F. Hayward, Julius S. Oguntoyinbo, Climatology of West Africa, page 29:
