The field surveys were conducted using the RK-GPR series of GPR systems, along with the QGPR (2DGPRMonitor) software for data acquisition. Antennas with frequencies of 100 MHz and 400 MHz were used in the surveys. At four locations—Hua Shi Xia, Hela Village, Shuang Cha Gou, and Mado Township—one survey line was established at each location. The length of each survey line was generally 100 meters; however, the survey line in Mado Township was 40 meters long. The spacing between survey points along the lines was 2 meters. The coordinates of the survey lines and points were obtained through GPS measurement. However, currently, only the coordinates of some of the survey lines are available. The raw radar echo data collected is stored in.GPRD format. The time sampling parameters vary among the different survey lines, and can be obtained from the corresponding raw data files.

It does not involve any purchase, download, or exchange of external datasets.", "ds_quality": "
The data quality control of this dataset is primarily reflected in the preservation of original data records, the traceability of acquisition parameters, and the recording of spatial location information. Original radar echo records are retained, and the time sampling parameters for different survey lines can be obtained from the corresponding raw data files. Some survey lines include GPS coordinates for their starting and ending points, which can be used to determine the spatial position, orientation, and approximate extent of the survey lines. However, the coordinate information for other points along the survey lines is not complete. Currently, this dataset only provides raw observation data. No further preprocessing steps such as background removal, band-pass filtering, gain compensation, or time zero calibration have been performed. Therefore, accuracy metrics for the processed data are not available at this time. In future studies, preprocessing steps can be carried out as needed, and the data quality can be evaluated in conjunction with radar profile characteristics and related auxiliary information.
", "ds_ref_way": "", "ds_abstract": "This dataset was collected during the survey of permafrost and underground ice in the Yellow River source area of the Tibetan Plateau from November 5th to 12th, 2024. The purpose of this survey is to characterize the subsurface structure at shallow depths, thereby providing geophysical data for studies on the distribution of underground ice and the characteristics of underground media in permafrost regions. Field observations were conducted using the RK-GPR series of ground penetrating radar systems, along with the QGPR (2DGPRMonitor) software for data acquisition. Two antenna frequencies were used: 100 MHz and 400 MHz. At four locations—Hua Shi Xia, Hela Village, Shuang Cha Gou, and Maduo Township—one survey line was deployed at each site. The length of each survey line was generally 100 meters; however, the survey line in Maduo Township was 40 meters long, with a measurement accuracy of 2 meters. The dataset primarily contains raw radar echo records, stored in.GPRD format. File names include information about the sampling location, such as “Hua Shi Xia.GPRD” and “Hua Shi Xia.rtk”. The coordinates of the survey points were obtained using GPS measurements. The study area is located in the northeastern part of the Tibetan Plateau, within the Yellow River source region. The geographical boundaries are approximately 95°50′E to 98°55′E and 33°32′N to 35°35′N. The time sampling parameters vary between different survey lines, and can be obtained from the corresponding raw data. This dataset uses dual-frequency ground penetrating radar for observation, while retaining the original echo records. It can be used for radar data processing, identification of shallow subsurface structures, and related geophysical studies involving permafrost and underground ice.\r\n\r\n
Users should read and analyze the data in conjunction with the collection parameters specified in the original data files. It is important to note that the time sampling parameters vary between different survey lines. The dataset currently does not include processed data that has undergone background removal, band-pass filtering, gain compensation, or time zero correction. Relevant processing should be carried out according to the specific research objectives. Each survey line has GPS coordinates for its start and end points, but the coordinate information for other points along the line is incomplete. Users should be aware of the limitations of spatial positioning information when using this dataset. Currently, the sharing status of this dataset is pending. Without permission from the data provider, it is not recommended to access or use any undisclosed data.
