HiWATER: Dataset of Hydrometeorological observation network (an automatic weather station of Sidaoqiao populus forest station, 2013)

This dataset includes data recorded by the Hydrometeorological observation network obtained from the automatic weather station (AWS) at the observation system of Meteorological elements gradient of Sidaoqiao populus forest station between 10 July, 2013, and 31 December, 2013. The site (101.124° E, 41.993° N) was located on a populous and tamarix forest (Populus euphratica Olivier. and Tamarix chinensis Lour.) surface in the Sidaoqiao, Dalaihubu Town, Ejin Banner, Inner Mongolia Autonomous Region. The elevation is 876 m. The installation heights and orientations of different sensors and measured quantities were as follows: air temperature and humidity profile (HMP45AC; 28 m, north), wind speed profile (010C; 28 m, north), two four-component radiometer (CNR4; 6 m and 24 m, south), two infrared temperature sensors (SI-111; 24 m, south, vertically downward), two photosynthetically active radiation (PQS-1; 24 m, south, one vertically upward and one vertically downward), soil heat flux (HFP01; 3 duplicates, -0.06 m), and soil temperature profile (109ss-L; 0, -0.02 and -0.04 m).The observations included the following: air temperature and humidity (Ta_28 m; RH_28 m) (℃ and %, respectively), wind speed (Ws_28 m) (m/s), 24 m four-component radiation (DR_1, incoming shortwave radiation; UR_1, outgoing shortwave radiation; DLR_Cor_1, incoming longwave radiation; ULR_Cor_1, outgoing longwave radiation; Rn_2, net radiation) (W/m^2), 6 m four-component radiation (DR_2, incoming shortwave radiation; UR_2, outgoing shortwave radiation; DLR_Cor_2, incoming longwave radiation; ULR_Cor_2, outgoing longwave radiation; Rn_2, net radiation) (W/m^2), infrared temperature (IRT_1 and IRT_2) (℃), photosynthetically active radiation of upward and downward (PAR_up and PAR_down) (μmol/ (s m^-2)), soil heat flux (Gs_1, Gs_2 and Gs_3) (W/m^2), and soil temperature (Ts_0 cm, Ts_2 cm, Ts_4 cm, Ts_10 cm, Ts_20 cm, Ts_40 cm, Ts_60 cm and Ts_100 cm) (℃).The data processing and quality control steps were as follows: (1) The AWS data were averaged over intervals of 10 min for a total of 144 records per day. Data during 16 July, 2013 and 17 July, 2013 were missing during the malfunction of datalogger. The soil heat flux (G3) was missing during 20 November, 2013 and 8 December, 2013 because the wire was break by the sheep. The missing data were denoted by -6999. (2) Data in duplicate records were rejected. (3) Unphysical data were rejected. (4) The data marked in red are problematic data. (5) The format of the date and time was unified, and the date and time were collected in the same column, for example, date and time: 2013-9-10 10:30. (6) Finally, the naming convention was AWS+ site no. Moreover, suspicious data were marked in red.For more information, please refer to Li et al.

本数据集收录了2013年7月10日至2013年12月31日期间，由水汽观测网络在锡达尔乔气象要素梯度观测站自动气象站（AWS）所采集的数据。观测点（东经101.124°，北纬41.993°）位于内蒙古自治区鄂尔多斯市东胜区达拉特旗沙道沟镇，一片密集的胡杨林和红柳林（胡杨树（Populus euphratica Olivier.）和红柳（Tamarix chinensis Lour.））之中，海拔高度为876米。不同传感器的安装高度和朝向以及测量量如下：空气温度和湿度剖面（HMP45AC；28米，北向）、风速剖面（010C；28米，北向）、两台四通道辐射计（CNR4；6米和24米，南向）、两台红外温度传感器（SI-111；24米，南向，垂直向下）、两台光合有效辐射仪（PQS-1；24米，南向，一台垂直向上，一台垂直向下）、土壤热通量（HFP01；3个重复，-0.06米）、以及土壤温度剖面（109ss-L；0米、-0.02米和-0.04米）。观测内容包括以下各项：空气温度和湿度（Ta_28 m；RH_28 m）（摄氏度℃和百分比%，分别）、风速（Ws_28 m）（米每秒m/s）、24米四通道辐射（DR_1，入射短波辐射；UR_1，出射短波辐射；DLR_Cor_1，入射长波辐射；ULR_Cor_1，出射长波辐射；Rn_2，净辐射）（瓦每平方米W/m^2）、6米四通道辐射（DR_2，入射短波辐射；UR_2，出射短波辐射；DLR_Cor_2，入射长波辐射；ULR_Cor_2，出射长波辐射；Rn_2，净辐射）（瓦每平方米W/m^2）、红外温度（IRT_1和IRT_2）（摄氏度℃）、向上和向下光合有效辐射（PAR_up和PAR_down）（微摩尔每平方秒每平方米μmol/ (s m^-2)）、土壤热通量（Gs_1，Gs_2和Gs_3）（瓦每平方米W/m^2）、以及土壤温度（Ts_0 cm，Ts_2 cm，Ts_4 cm，Ts_10 cm，Ts_20 cm，Ts_40 cm，Ts_60 cm和Ts_100 cm）（摄氏度℃）。数据处理和质量控制步骤如下：（1）AWS数据以10分钟为间隔进行平均，每天总计记录144条记录。2013年7月16日和17日因数据记录仪故障，数据缺失。（2）20 November, 2013和8 December, 2013期间，由于羊群破坏电线，土壤热通量（G3）数据缺失。缺失数据以-6999表示。（3）重复记录的数据被拒绝。（4）非物理数据被拒绝。（5）数据标记为红色的为问题数据。（6）日期和时间格式统一，日期和时间收集在同一列中，例如，日期和时间：2013-9-10 10:30。（7）最终，命名规范为AWS+站点编号，并对可疑数据进行红色标记。欲了解更多信息，请参阅参考文献部分中的Li等（2013）（关于水汽观测网络或站点信息），刘等（2011）（关于数据处理）。
