absorptance

[əb′sȯrp·təns]
(physics)
The ratio of the total unabsorbed radiation to the total incident radiation; equal to one (unity) minus the transmittance.

absorptance

In illumination engineering, the ratio of the absorbed flux to the incident flux.

In this case the absorptance is expressed as relative units (dimensionless) and thus ETR is presented as nmol electrons [m.
A light weave fabric with appropriate visible light transmittance and low absorptance is recommended to allow more sunlight into the classroom, while reducing cooling loads.
The application of a single layer of Cu-Co-Mn-O with 50-100 nm thickness on SS resulted in absorptance of 0.
Although the transmission in the first gap remains zero, the reflectance is not equal to unity because of strong absorptance there.
Absorptance spectra were constructed from visual pigment templates (Stavenga et al.

Dry matter accumulation is the product of incident solar radiation at the earth's surface (I), the absorptance of solar irradiance by the maize canopy ([alpha]), and the efficiency of conversion of absorbed radiant energy into maize dry matter (e) (Tollenaar and Dwyer, 1999).

Since the solar absorptance and the longwave emittance of the same surface can be quite different, the shortwave and the longwave radiative fractions should be used separately to better reflect actual radiation interchanges in the room.
