近地面折射率结构常数的长期测量和统计分析
Long-term measurements and statistics study on refractive index structure parameter of surface layer
摘要
统计分析1997～2000年合肥地区一复杂地形处近地面折射率结构常数C2n的测量数据.给出了不同下垫面、不同季节、不同高度上C2n的统计结果.白天C2n强弱依次为6月、5月、4月、9月、1月.白天水面上C2n比草地上小,夜间比草地上大.不论白天还是夜晚,近地面C2n都随高度递减,且3～10m高的C2n递减较慢,10～15m高的C2n递减较快.C2n随月份的日变化与模式计算结果基本一致.亮
Abstract
The data of C 2 n refractive index structure parameter from 1997 to 2000 at a complex terrain in Hefei are studied statistically.Results of C 2 n in different ground covers,different seasons,different heights are presented. Months goes when C 2 n in daytime from strong to weak are June, May, April,September,January. The C 2 n over the grass are larger than that over the water in daytime,while the result of the comparison in nighttime is the reverse.The C 2 n decreases with altitude increase both in day and at night. The C 2 n falls slower from 3 to 10m than 10 to 15m. C 2 ns measured and modeled agree well with each other.
