边界层气象要素

SACOL's Instruments      边界层气象要素的测量包括:1,2,4,8,12,16,32m的风速、气温和相对湿度;8m的风向;地表红外温度;大气压;降水量。

     Boundary layer meteorological measurements include wind speed (014A-L, Met One), air temperature and relative humidity (HMP45C-L, Vaisalla) at 1, 2, 4, 8, 16 and 32 m, and wind direction (034B-L, Met One) at 8 m, with signals logged to a data logger (CR23X, Campbell) and recorded at half-hour intervals. The measurement of skin temperature is made with a Precision Infrared Thermocouple Sensor (IRTS-P, Apogee). Barometric pressure is measured using a CS105 Barometric Pressure Sensor (Vaisala) over a 600 to 1060 millibar range. Precipitation is measured with a tipping bucket Rain Gage (TE525MM-L, Texas Electronics) in 0.1 mm increments.
