تشميس

Annual mean insolation, at the top of Earth's atmosphere (top) and at the planet's surface.

US annual average solar energy received by a latitude tilt photovoltaic cell (modeled).

Average insolation in Europe.

التشميس Insolation أو الإشماس مصطلح يشير الى كمية الطاقة الشمسية التى يتلقاها سطح من السطوح.

اثر الإسقاط

Past and future of daily average insolation at top of the atmosphere on the day of the summer solstice, at 65 N latitude. The green curve is with eccentricity e hypothetically set to 0. The red curve uses the actual (predicted) value of e. Blue dot is current conditions, at 2 ky A.D.

توزيع تشمس في الجزء العلوي من الغلاف الجوي

Spherical triangle for application of the spherical law of cosines for the calculation the solar zenith angle Θ for observer at latitude φ and longitude λ from knowledge of the hour angle h and solar declination δ. (δ is latitude of subolar point, and h is relative longitude of subsolar point).

$\stackrel{\mathrm{d}\mathrm{a}\mathrm{y}}{\bar{Q}}$, the theoretical daily-average insolation at the top of the atmosphere. The calculation assumed conditions appropriate for 2000 A.D.: a solar constant of S₀=1367 W m^-2, obliquity of ε=23.4398°, longitude of perihelion of ϖ=282.895°, eccentricity e=.016704. Contour labels (green) are in units of W m^-2.
