【摘要】 用１９８６－１９９５年的１０年探空气象资料，在塔塔尔斯基模式下，计算了我国天文台及候选台址所在的１０个地区的Ｆｒｉｅｄ参数ｒ０给出了地面、９００米、１５００米、３０００米、５０００米各高度上的ｒ０年平均值．在３０００米高度上冬季丽江视宁度最好，夏季酒泉最好，均达到相应季节定日４３０１米高度上视宁度水平．更多还原

【Abstract】 On utilizing standard meteorological radiosonde data in the years 1986-1995 the Fried parameter r0 are calculated by means of the model of Tatarskii over 10 regions of astronomical observatories and potential astronomical sites in China The annual mean r0 at ground and at the heights of 900 m, 1500 m, 3000 m, 5500 in above sea level are given. On the height of 3000 m above sea level the seeing quality over Lijiang in winter and over Jiuquan in Summer ,is the best respectively. That corresponds to the Seeing quality over Dingri at the height of 4301 m above sea level.更多还原
