radiant flux

The total power emitted or received by a body in the form of radiation. It is measured in watts.

Radiant flux

Radiant flux is radiant energy per unit of time. The standard unit for measuring radiant flux is the watt (W), which is defined as Joules per second (J/sec).

To create the level 3 data products, the level 2 CERES fluxes are aggregated to construct hourly 1[degrees] x [degrees] gridded mean TOA radiant fluxes (Doelling et al.
The NUVA77 series comes in wavelengths from 365nm ~ 405nm, radiant flux of 2600mW ~ 3100mW at 500mA, ideal for UV curing, photo catalyst and sensor light applications.
It shows that the average short-wave radiant flux is higher than the other three fluxes and the average sensible heat flux is lower than the average for each of the other three fluxes in Cha-bahar Bay.
The radiant flux K[PHI] may be thought of as aether energy at the velocity of light, which is bound in the line of distance R between the gravitating masses, representing the gravitational energy K[PHI]L2/Rc and the equivalent virtual gravitational mass K[PHI]L2/[Rc.sup.3] that belongs to the binary system.
(6) Thus, assuming that the reciprocity law is obeyed, the same photoresponse should be observed when exposures are made: (1) at a high radiant flux for a short period of time (e.g., Figure 1a); (2) at a low radiant flux for a long period of time (e.g., Figure 1b); (3) by repeatedly cycling a light source on and off and controlling both the on/off frequency of the light and the length of time that the light remains in the on and the off state (e.g., Figure 1c).
BivarOpto, the Optoelectronics Division of Bivar Inc, Irvine, CA, has introduced what they describe as the industry's first extended-life, high-powered ultraviolet LEDs featuring typical radiant flux of 12 mW per chip and a typical stable wavelength of 400 nm.
The major concept is the flow of light in a space, reminiscent of David DiLaura's pioneering work in radiant flux transfer which begat a significant portion of what we now know as computer simulation of light.

This theory is not valid for small-size droplets (diameter-to-wavelength) [2] but is used to determine local radiant flux in droplets.
