CAMEX-4 ER-2 HIGH ALTITUDE DROPSONDE V1

The CAMEX-4 ER-2 High Altitude Dropsonde dataset was collected by the ER-2 High Altitude Dropsonde System (EHAD), which used dropwinsondes fitted with Global Positioning System (GPS) receivers to measure the atmospheric state parameters (temp, humidity, windspeed/direction, pressure) and location in 3 dimensional space during the sonde's descent once each half second. Measurements was transmitted to the aircraft from the time of release until impact with the ocean's surface.CAMEX-4 ER-2 高空探测气球数据集由高空探测气球系统（EHAD）收集而成，该系统配备装有全球定位系统（GPS）接收器的dropwinsondes，用以测量大气状态参数（温度、湿度、风速/风向、气压）及其在三维空间中的位置，在气球下降过程中，每半秒钟进行一次测量。测量数据自释放时刻起直至气球触及海面，均通过无线电传输至飞机上。
