| 英文摘要 | Starting November 1999 we are carrying out simultaneous seeing observations with the Solar Differential Image Motion Monitor (S-DIMM) at the Fuxian Lake station of the Yunnan Observatory and a solar scintillometer of the type used in the recent site survey by one of us (Beckers et al., 1997). The purpose was to compare the two methods of assessing the daytime atmospheric seeing for a lake site. We report here the first results of this comparison. We find that the relation between the seeing as measured by the S-DIMM (the Fried parameter r(0)) and the scintillation in the solar irradiance (sigma (I)) differs greatly from the relation found by Seykora (1993) for NSO/Sac Peak. We conclude that the sigma (I) measurements give a good indication for the amount of near-Earth seeing but that they are a poor proxy for the total atmospheric seeing. We interpret the simultaneous (r(0), sigma (I)) observations in terms of an atmospheric seeing model and find good quantitative agreement with a model in which a fraction (alpha) of the seeing originated near the Earth (ground or water) and the rest (1-alpha) originates at higher layers. For lake sites alpha is small all day and the seeing is determined primarily by the refractive index variations at higher atmospheric layers. For land sites alpha is small in the early morning but rapidly increases as the day progresses, near-Earth seeing dominating there most of the time. |
