1999年8月11日，在法国的坎皮斯特罗斯观测到一次接近日全食（80%）。这一特殊事件对大气边界层的影响是用超高频RASS雷达、声雷达和装有仪器的桅杆观测的。湍流强度，雷达反射率和温度的变化对辐射收支的描述与配置地面气象数据。日食的影响引起了大气层的明显反应，时滞为15至30分钟，在大气边界层顶部的几个平均和湍流气象变量中可以察觉。
On 11 August 1999, a near-total solar eclipse (80%) was observed in Campistrous, France. The influence of this particular event on the atmospheric boundary layer was observed with a UHF-RASS radar, a sodar and an instrumented mast. The changes in turbulence intensity, radar reflectivity, and temperature on the radiative budget are described in relation to collocated ground meteorological data. The impact of the eclipse induces a clear response of the atmosphere, with a time lag of 15 to 30 min, perceptible in several mean and turbulent meteorological variables up to the top of the atmospheric boundary layer.
