Daily and annual patterns of light and temperature. Sunlight and temperature patterns in locations representing different latitudinal zones, 10°N (Caracas, Venezuela; 10.5°N, 66.9°W), 30°N (New Orleans, LA, USA; 30.0°N, 90.0°W), and 55°N (Copenhagen, Denmark; 55.7°N, 12.6°E). A, Hourly solar radiation (Wh m−2) and (B) hourly temperature (°C) for a clear day in each location near the spring equinox (March), summer solstice (June), fall equinox (September), and winter solstice (December) in 2020. Arrows in (B) indicate dawn and dusk. C, Average monthly temperature (°C) and daylength (h) within each location in 2020. Average solar radiation and daylength plots modeled based on data from the “Global Solar Atlas 2.0” (https://globalsolaratlas.info) and Weather Spark (https://weatherspark.com/); temperature data obtained from Time and Date AS (https://www.timeanddate.com/).
