Abstract

In a recent article [Appl. Opt. 34, 1598 (1995)] a new pyrgeometer formula was proposed. This formula leads to a bias at isothermal conditions. The origin of the bias is explored by a more rigorous treatment of the radiation processes involved in the energy balance of a pyrgeometer. As a result it is found that, for an accuracy of a few watts per square meter, the spectral transmission characteristics of the dome have to be taken into account.
