本数据集为2025年裴家峁沟流域雨量站降水观测数据。裴家峁沟流域位于陕西省榆林市绥德县，属于无定河一级支流。数据包括流域站网布设图、逐日降水量表、降水量摘录表、各时段最大降水量表。裴家峁沟流域雨量站基本情况等详见《裴家峁沟流域2025年情况说明》。观测指标为降水量（mm）。

This dataset is the precipitation observation data from the rainfall station in the Peijiamaogou Basin in 2025.

The data includes the basin station network layout map, daily precipitation scale, precipitation extract table, and maximum precipitation scale for each period. For the basic information of the rainfall stations in the Peijiamaogou Basin, please refer to the \"Situation Description of the Peijiamaogou Basin in 2025\". The observation indicator is precipitation (mm).

The DSJ2 automatic rainfall gauge uses a 24-hour recording system for annual or flood season observations. The SM1 ordinary rainfall gauge uses an 8-hour/20-hour recording system for annual observations. In case of failures with the automatic rainfall gauge, data from the ordinary rainfall gauge can be used to supplement the measurements. The main task is to record the start and end times of precipitation events, and to calculate the total precipitation amount. If there is a gap of more than 15 minutes between precipitation events, those intervals will be recorded as two separate precipitation events. If the gap is less than 15 minutes, it will be recorded as a single precipitation event. If a precipitation event spans across both 8-hour and 20-hour periods, measurements should be taken at both times. The data from the automatic gauge is recorded using a two-hour recording system, and a summary table is created. The maximum precipitation amounts for each time period are calculated using computers.", "ds_ref_instruction": "" } }, "submit_center_id": "ncdc", "data_level": 0, "recommendation_value": 0, "license_type": "https://creativecommons.org/licenses/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, "belong_to_nieer": false, "allow_update_data": false, "created_from": "fair", "ds_topic_tags": [ "降水摘录", "最大降水量", "时段降水量", "日降水量" ], "ds_subject_tags": [], "ds_class_tags": [], "ds_locus_tags": [ "榆林", "绥德", "裴家峁沟", "陕西省" ], "ds_time_tags": [ 2025 ], "ds_contributors": [ { "true_name": "黄河水土保持绥德治理监督局（绥德水土保持科学试验站）", "email": "hhstbcsdzljdj@163.com", "work_for": "黄河水土保持绥德治理监督局（绥德水土保持科学试验站）", "country": "中国" } ], "ds_meta_authors": [ { "true_name": "麦旭东", "email": "hhstbcsdzljdj@163.com", "work_for": "黄河水土保持绥德治理监督局（绥德水土保持科学试验站）", "country": "中国" } ], "ds_managers": [ { "true_name": "黄河水土保持绥德治理监督局（绥德水土保持科学试验站）", "email": "hhstbcsdzljdj@163.com", "work_for": "黄河水土保持绥德治理监督局（绥德水土保持科学试验站）", "country": "中国" } ], "category": "水土保持" }
