Atmospheric boundary layer intensive sounding data at Cangzhou site

This dataset is obtained from a field experiment of intensive GPS (Global
Positioning System) boundary layer sounding carried out in
Cangzhou (38.3°N, 116.84°E), from 26 November to 26 December
2019. Eight soundings were taken in each day, at 02:00, 05:00, 08:00,
11:00, 14:00, 17:00, 20:00 and 23:00 BJT (i.e., UTC + 8). GPS radiosonde
(Beijing Changzhi Sci & Tech Co. Ltd., China) was used to obtain
profiles of wind, temperature, humidity and PM2.5 mass concentration with
a vertical resolution of approximately 3-5 m (1 s interval in
time).  The ABL height was derived via the bulk
Richardson number method.

本数据集来源于2019年11月26日至12月26日在沧州（北纬38.3°，东经116.84°）开展的密集型GPS（全球定位系统）边界层探测野外试验。每日进行8次探测，时间为北京时间（BJT，即UTC+8）的02:00、05:00、08:00、11:00、14:00、17:00、20:00和23:00。使用中国北京长治科技有限公司生产的GPS探空仪获取风、温度、湿度和PM2.5质量浓度的廓线，其垂直分辨率约为3-5米（时间间隔1秒）。大气边界层（Atmospheric Boundary Layer, ABL）高度通过整体理查森数法推导得出。
