【摘要】：天文選址的決策和激光傳輸系統(tǒng)的設(shè)計(jì)和應(yīng)用需要掌握大氣光學(xué)湍流的時(shí)空變化規(guī)律。利用HTP-2型溫度脈動(dòng)儀測(cè)量近地面湍流,用大氣相干長(zhǎng)度儀測(cè)量整層湍流積分效應(yīng)。分析折射率結(jié)構(gòu)常數(shù)C2n的實(shí)測(cè)數(shù)據(jù),得到近地面光學(xué)湍流月平均和季平均的變化規(guī)律。分析了早晚兩個(gè)"轉(zhuǎn)換時(shí)刻"不同參數(shù)的變化規(guī)律。根據(jù)廣義Hufnagel-Valley模式反演得到夜間、白天及"轉(zhuǎn)換時(shí)刻"整層湍流廓線,比較了不同時(shí)刻湍流廓線的特點(diǎn)。在連續(xù)多年實(shí)測(cè)數(shù)據(jù)的基礎(chǔ)上所得結(jié)論全面可靠,具有重要的工程參考價(jià)值。
[Abstract]:The decision of astronomical location and the design and application of laser transmission system need to master the temporal and spatial variation of atmospheric optical turbulence. The near-surface turbulence is measured by HTP-2 temperature pulsator. The integral effect of whole layer turbulence is measured by atmospheric coherent length meter. The measured data of refractive index structure constant C2n are analyzed. The variation law of the monthly and quarterly mean of optical turbulence near the ground is obtained. The variations of the different parameters of the two "transition times" in the morning and evening are analyzed. Based on the inversion of the generalized Hufnagel-Valley model, the turbulent profiles of the whole layer at night, during the day and at the "transition time" are obtained. The characteristics of turbulent profiles at different times are compared. Based on the measured data for many years, the conclusions are comprehensive and reliable, and have important engineering reference value.
