土壤温度：扁都口样带1、扁都口样带2、扁都口样带3、扁都口样带4、扁都口样带5、扁都口样带6、扁都口样带7测量了土壤温度。\n
\n粗糙度测量：采用粗糙度板和照相机测量。处理结果：数据中文件名中含有“result”字段的文件为粗糙度的处理结果，第一列为表面高度均方根高度，其实只有一个值，所以该列数据都相同；第二列为距离，第三列为相关函数值。当相关函数值为1/e时的距离值为相关长度；单位为：cm。\n
\n由于地表粗糙度在一定时期内变化不大，所以在该天前后的样方内的地表粗糙度都可以采用今天的数据。存在问题：从数据看，由于测量人员经验不足，某些照片效果不好。通过人工读取照片上的地表起伏剖面，得到1cm间隔的地表起伏高度值，写入记事本文件。然后通过程序计算地表的粗糙度中的均方根高度和相关长度", "ds_quality": "

On May 25, 2008, the ground synchronous observation test for airborne microwave radiometer (L & K band) was carried out in the Bian Du Kou encrypted observation area.\n
\nThe measurement contents mainly include surface soil temperature, surface roughness and ground penetrating radar.\n
\nThe soil temperature was measured by flat mouth sample band 1, flat mouth sample band 2, flat mouth sample band 3, flat mouth sample band 4, flat mouth sample band 5, flat mouth sample band 6 and flat mouth sample band 7. The roughness was measured by roughness plate and camera. Ground penetrating radar and TDR data are measured at the same time.

\nRoughness measurement: roughness plate and camera are used for measurement. Processing result: the file with \"result\" field in the file name in the data is the processing result of roughness. The first column is the surface height root mean square height. In fact, there is only one value, so the data in this column are the same; The second column is the distance and the third column is the correlation function value. When the correlation function value is 1 / E, the distance value is the correlation length; Unit: cm.\n
\nSince the surface roughness changes little in a certain period of time, the surface roughness in the quadrat before and after that day can use today's data. Existing problems: from the data, due to the lack of experience of surveyors, the effect of some photos is not good. Manually read the surface relief profile on the photo, obtain the surface relief height value with an interval of 1cm, and write it into the notepad file. Then, the root mean square height and correlation length of surface roughness are calculated by program", "ds_ref_instruction": " " } }, "submit_center_id": "ncdc", "data_level": 0, "license_type": "CC BY 4.0", "doi_reg_from": "reg_local", "cstr_reg_from": "reg_local", "doi_not_reg_reason": null, "cstr_not_reg_reason": null, "is_paper_in_submitting": false, "ds_topic_tags": [ "GPR探地雷达", "地表粗糙度", "土壤水分", "土壤温度", "TDR", "地面同步观测", "L波段机载微波辐射计", "K波段机载微波辐射计" ], "ds_subject_tags": [ "自然地理学" ], "ds_class_tags": [], "ds_locus_tags": [ "黑河流域", "扁都口加密观测区", "上游寒区水文试验区" ], "ds_time_tags": [ 2008 ], "ds_contributors": [ { "true_name": "赵少杰", "email": "geo_zhao@126.com", "work_for": "北京师范大学", "country": "中国" } ], "ds_meta_authors": [ { "true_name": "赵少杰", "email": "geo_zhao@126.com", "work_for": "北京师范大学", "country": "中国" } ], "ds_managers": [ { "true_name": "赵少杰", "email": "geo_zhao@126.com", "work_for": "北京师范大学", "country": "中国" } ], "category": "遥感及产品" }
