transmittance 

A measure of transmission expressed as the ratio of the intensity of the transmitted light I′ to the intensity of the incident light I, for a specified wavelength, i.e. T = I′/I. It is usually given as a percentage, i.e. T = I′/I ✕ 100. Syn. total transmittance. See absorbance; optical density.

To investigate how W affects broadband transmittance through a hypothetical atmosphere consisting of water vapour only, we have to use some kind of radiative transfer model.

This can be used to explain why the change in the transmittance of natural snowcovered ice was dominated not only by the thickness but also by the stratigraphy, and why the bare ice in Peipsi had the smallest transmittance compared with other cases.
For light transmittance measurements, it is the sample turning.

Some manufacturers use transmittance specifications targeted at less-than-nominal layer thickness to protect against the possibility of an individual layer being thinner than desired.

As mentioned above, the aim of this project was to determine the reliability of the calculation method, presented in the standard (EN ISO 6946:1997), used for calculating the influence of air gaps on thermal resistance of horizontally laid thermal insulation layers, compare these results with the measurements of thermal conductivities and to determine the corrections to thermal transmittance value of horizontally laid thermal insulation, which is enlarged due to the formed air gaps.
