CORRECTION OF ERRORS ASSOCIATED WITH MEASUREMENT OF NET ALL-WAVE RADIATION WITH DOUBLE-DOMED RADIOMETERS

Comparisons between measurements of net all-wave radiation made with double and single-domed radiometers have confirmed the existence of a significant offset between the two types of instrument. The availability in the UK and Niger, West Africa, of independent instruments to measure all the radiation components indicated that the double-domed instrument was in error and permitted the determination of a correction factor which is shown to be dependent on net long-wave radiation balance. It is also shown that this factor can be expressed in terms of the more often available net short-wave radiation balance so that retrospective correction of net radiation data is possible. © 1990 Kluwer Academic Publishers.
