| Abstract | The construction of a directional radiometer for measuring longwave radiation from the atmosphere is described. The instrument had a filter of black polyethylene to exclude solar radiation, and the detector was a thermopile. By analysis of the radiation and heat balances of the thermopile, correction terms are derived for (i) the flux density of radiation received by the thermopile from the filter, and (ii) the dependence of instrument sensitivity on temperature. Measurements with the new instrument of the equivalent flux density below cloudless skies at zenith angle 52.5° agree well with measurements of hemispheric flux density derived from simultaneous measurements with a Linke-Feussner actinometer. |
