In a similar study, Wang, Liang, He and Shi (2015-in this issue) propose
a new algorithm to estimate the clear-sky instantaneous all-wave
net radiation over the land surface by combining VSWIR and TIR remote
sensing data in a synergistic manner. The new method is based on extensive
modeling of atmospheric radiative transfer over the entire
solar spectrum. Validation with one-year measurements at seven Surface
Radiation Budget Network (SURFRAD) sites demonstrate that the
new method can accurately estimate clear-sky instantaneous all-wave
net radiation with a root mean square error (RMSE) of 70.6 W m−2
,
which is more accurate than the method of separating shortwave and
longwave components.
