Measurements of wind, temperature, pressure and humidity during the ascending profile 20130306_T3 with POLAR 5@en

Altitude (geopotential) is calculated from measured atmospheric static pressure, where the offset in the original data due to the reference pressure at departure was corrected using radar altimeter measurements during lowlevel flight legs between the vertical profiles位势高度（geopotential）由实测大气静压计算得到，原始数据中因起飞阶段参考气压引入的偏差，可借助垂直剖面之间低空飞行航段的雷达高度计测量值完成校正。
