Are there multiple versions of the dataset? no METHODOLOGICAL INFORMATION 1. Description of methods used for collection/generation of data: 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). 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). 2. Methods for processing the data: The profiles were smoothed by the three-point moving average method and were interpolated to obtain a vertical resolution of 50m. The ABL height is derived via the bulk Richardson number method DATA-SPECIFIC INFORMATION FOR: [ABLH&uv.txt] 1. Number of variables: 4 2. Number of cases/rows: 240 3.
