Abstract
A series of nomograms is presented showing the longwave radiation temperature correction for various thermocouple wire diameters, different values of emitted and absorbed radiation, and for wind speeds from zero to 10 m sec−1. The temperature correction is computed from the steady-state balance between radiative and convective heat transfers and is to be added to the measured temperature. The radiation field is based upon previous measurements made under clear nighttime skies and the free and forced convection correlation formulae are adopted from wind tunnel experiments.
