Irradiance in a sentence

Using our more sensitive spectroradiometer, UV irradiance is discernible starting at ~300 nm.

At constant high irradiance, the rate of carbon assimilation increases as the temperature is increased.

At zenith, sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level.

Bright sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level.

Composition and power Solar irradiance spectrum above atmosphere and at surface.

For example, in optics two or more coherent lightwaves may interact and by constructive or destructive interference yield a resultant irradiance deviating from the sum of the component irradiances of the individual lightwaves.

For some special applications or applications where the heat treatment is done on an edge or corner of the part, it may be better to have the irradiance decrease near the edge to prevent melting.

Hadley cells are the mechanism by which equatorial generated ozone in the tropics (highest area of UV irradiance in the stratosphere) is moved poleward.

In remote sensing applications, anisotropy functions can be derived for specific scenes, immensely simplifying the calculation of the net reflectance or (thereby) the net irradiance of a scene.

Instead, the irradiance falls off gradually away from the center of the beam.

In the early 20th century, Frederick Blackman and Gabrielle Matthaei investigated the effects of light intensity ( irradiance ) and temperature on the rate of carbon assimilation.

It is also the strongest output range of the Sun's total irradiance spectrum.

Models are unable to reproduce the rapid warming observed in recent decades when they only take into account variations in total solar irradiance and volcanic activity.

One consideration crucial to the success of a heat treatment operation is control of the laser beam irradiance on the part surface.

On the other hand, the fundamental diurnal tide labelled (1, −2) which is most efficiently excited by solar irradiance is an external wave and plays only a marginal role within lower and middle atmosphere.

Phytoplankton blooms are believed to be limited by irradiance in the austral (southern hemisphere) spring, and by biologically available iron in the summer.

The contribution of solar irradiance to radiative forcing is 5% the value of the combined radiative forcing due to increases in the atmospheric concentrations of carbon dioxide, methane and nitrous oxide.

The optimal irradiance distribution is driven by the thermodynamics of the laser-material interaction and by the part geometry.

These measurements indicate that the Sun's total solar irradiance has not increased since 1978, so the warming during the past 30 years cannot be directly attributed to an increase in total solar energy reaching the Earth (see graph above, left).

The transmittance is related to t by:sfn : The factor of n 2 /n 1 occurs from the ratio of intensities (closely related to irradiance ).
