WebFeb 8, 2013 · The length of the daylight changes during the year because of Earth's tilt. As the Earth orbits the sun, its tilt causes the northern and southern hemispheres to alternate between greater and lesser exposure to the sun. As a hemisphere is tilted away from the sun, the length of a day becomes shorter. WebDLI is usually calculated by measuring the photosynthetic photon flux density (PPFD) in μmol·m −2 ·s −1 (number of photons in the PAR range received in a square meter per second) as it changes throughout the day, and then using that to calculate total estimated number of photons in the PAR range received over a 24-hour period for a specific area. WebYou can simply use the longest and shortest day of the year to fit the sine f ( x) = a ⋅ sin ( ω x − x 0) + b. Depending on your choice of scale, x will be in days or something else.
