资源简介:
2008年5月26日至7月29日在临泽站开展凝结水观测。观测地点在临泽站内的沙丘上。
观测方法:先后采用了两种容器进行观测。分别为凝结水盘(2008-05-26至2008-07-08)和铝盒(2008-06-24至2008-07-29)。凝结水盘采用敞口长方形塑料盘,见缩略图。铝盒的布置采用了遮盖和不遮盖两种方法,将3组深度不同的铝罐,分别布在沙丘的不同高度上。
称重仪器:凝结水盘用美国双杰G&G TC30K- H电子天平。精度1g;铝盒法用500g电子天平。精度0.1g。
观测时间:早上6:00-7:00之间;晚上19:00-22:00之间。受天气条件限制,称重时间不完全一致。
连续观测:凝结水盘进行了一次连续观测,6月25日至6月27日,时间间隔为2小时;铝盒进行了两次连续观测,6月25日至6月27日,7月19日至7月20日,两次观测的时间间隔均为2小时。
凝结水预处理数据根据早晚称重重量之差计算凝结水的重量,再除以其体积,得到凝结水量(mm)。
Condensate water observations were conducted at the Linze Station from May 26 to July 29, 2008, with the observation site situated on a sand dune within the station grounds.
Two types of containers were used sequentially for the observations: the condensate pan (used from May 26 to July 8, 2008) and aluminum boxes (used from June 24 to July 29, 2008). The condensate pan was an open rectangular plastic tray, as depicted in the attached thumbnail. For the aluminum box method, two setups (covered and uncovered) were employed, with three groups of aluminum cans of varying depths arranged at different heights on the sand dune.
For weighing instruments: the condensate pan was measured using a US G&G TC30K-H electronic balance with a precision of 1 g; the aluminum box method utilized a 500 g electronic balance with a precision of 0.1 g.
Observations were conducted between 6:00–7:00 and 19:00–22:00 local time daily. However, the exact weighing times were not fully consistent due to weather constraints.
A single continuous observation was carried out for the condensate pan from June 25 to June 27, 2008, with a 2-hour interval between measurements. Two continuous observations were performed for the aluminum box method: one from June 25 to June 27, 2008, and another from July 19 to July 20, 2008, both with a 2-hour interval between sampling points.
Preprocessing of the condensate data involved calculating the condensate mass as the difference between the morning and evening weighing values, then dividing this mass by the corresponding volume to derive the condensate water depth in millimeters (mm).
