The paper considers the impact of ship oscillations on the accuracy of radiation flux measurements in the absence of a gyroplatform
and a gimbal suspension. As an example, we discuss the simultaneous determinations of the radiation fluxes and careen during
the 20th mission of the R/V Akademik Joffe. A sampling rate of 10 s was found to be sufficient to neglect the careen when estimating the hourly sums of the short-wave
solar radiation at sun heights exceeding 10°. At smaller sun heights, the careen is able to effect the estimates of the solar
radiation within 20%. Due to the harmonic nature of such oscillations, these errors tend to become low against the instrumental
accuracy if one deals with the hourly and daily means of the short-wave solar radiation fluxes during sufficiently long observations.
In addition, a significant effect occurs at rather low sun and a sea roughness of Beaufort number 4 or higher. A rough sea
is usually associated with the diminishing of the clear sky area and the higher repeatability of the cloudiness conditions,
which reduces the effect of rolling upon the measurement accuracy. 相似文献
