论文摘要
大气中有很多各种振荡动作,例如内部重力波(IGW),它们的时间比辐射射线通道的时间少。振荡动作导致空气质量转移时的绝热冷却,从平衡或热量移动时。辐射时测量时,从特定体积空气的平衡状态转移的大小和迹象是未知的。因此,相对于平衡温度,测得的(基本上是瞬时)温度的位移是未知的。在某些情况下,这些错误可能达到10度或更高的值。提出了用于校正这些效果的算法。校正算法计算了辐射范围从多项式曲线的垂直位移的移位。温度的校正是作为干绝热失气速率和辐射高度移位的产物计算的。从测得的温度中减去结果。在移位值的依赖性方面校正了观察到的高度。
There are a lot of oscillatory motions of various kinds in the atmosphere, for example, internal gravity waves (IGW), which have a period less than the time of flight of the radiosonde. Oscillatory motions lead to adiabatic cooling during the shift of air mass upwards from equilibrium or heat when shifting down. The magnitude and sign of the shift from the equilibrium state of a specific volume of air at the time of measurements by radiosonde are unknown. Therefore the displacement of measured (essentially instantaneous) temperature is unknown relative to the equilibrium temperature. These errors in some cases can reach values of 10 degrees or more. The algorithm for correcting of these effects is proposed. The algorithm of correction calculates the shift of the vertical displacement of the radiosonde from the polynomial curve. The correction for temperature is calculated as a product of the dry adiabatic lapse rate and the shift of the radiosonde altitude. The result is subtracted from the measured temperature. The observed height is corrected in dependence of the shift value.
