摘要
本文利用南极瑞穗站１９７９年太阳可见光波段直接辐射的分光测量和微气象观测资料￣［１－２］。分别计算了整层大气、分子大气、臭氧和气溶胶的散射和吸收所构成的光学厚度τｔ（λ）、τＲ（λ）、τ＿（０３）（λ）和τ＿ａ（λ）及埃斯屈朗浑浊度系数β和波长指数α，并与北京和拉萨的相应值进行了比较￣［３－５］。文中对波长指数和埃斯屈朗浑浊度系数及整层大气垂直光学厚度与大气稳定度参数、湍流热通量的关系也进行了讨论。
In this paper, using measurements of solar visible waveband directr spectral radi-ation and micrometeorological components in the surface layer over Mizuho station inAntarctica in 1979. The total atmospheric vertical optica1 thickness τ_t(λ), the atmosphe-ric molecular diffuse optical thickness τ_R(λ), ozone absorption optical thickness τ_(03)(λ),aerosol diffuse optical thickness τ_t(λ), turbidity coefficientβand wave lengthexponent α have been caculated respectivety. They have been compared with that inBeijing and Lhasa and relationships of they with atmospheric stability and turbulent heat flux was discussed.
