Field notes
The artwork separates a selected date into daylight, twilight, and night, with each field sized according to its duration at the chosen latitude. Colour is informed by atmospheric and astronomical inputs, including temperature, cloud, rain, sun, season, and moon. The site says recorded weather is used when available, while dates without suitable records receive typical seasonal weather and an accompanying disclosure.
