地表热通量（G₀）是陆地表面能量平衡的重要组成部分，反映地表与土壤之间热量传输及土壤能量储存和释放过程，对认识高寒地区冻土热状况、陆气相互作用以及气候变化响应具有重要意义。本数据集基于已发表的1982-2015年三江源9层、空间分辨率为0.01°×0.01°土壤温度数据集，结合土壤水分等资料，采用动态土壤导热率参数化方案计算土壤温度变化引起的地表热通量，并进一步考虑土壤冻融过程中的相变潜热，获得三江源地区1982-2015年逐月地表热通量（G₀）数据。数据空间分辨率为0.01°×0.01°，时间分辨率为月尺度，单位为W m⁻²。G₀以土壤吸收能量为正、向大气释放能量为负，能够反映研究区域地表热量输入和输出的季节及年际变化。结果表明，1982-2015年三江源地区G₀年均值总体为正，区域平均值为0.113 W m⁻²，表明研究时段内三江源地区土壤总体表现为净吸收能量。G₀具有显著的季节变化特征，春夏季总体表现为吸热，秋冬季总体表现为放热，其中5月吸收热量较强，12月释放热量最为明显。", "ds_source": "", "ds_process_way": "", "ds_quality": "", "ds_acq_start_time": "1982-01-01 00:00:00", "ds_acq_end_time": "2015-12-31 00:00:00", "ds_acq_place": "三江源区", "ds_acq_lon_east": null, "ds_acq_lat_south": null, "ds_acq_lon_west": null, "ds_acq_lat_north": null, "ds_acq_alt_low": null, "ds_acq_alt_high": null, "ds_share_type": "apply-access", "ds_total_size": 2870693304, "ds_files_count": 0, "ds_format": "*.nc", "ds_space_res": "0.01°×0.01°", "ds_time_res": "月", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "fb363b92-cfdd-4dc4-9b01-ea7ade0f1f1b.png", "ds_thumb_from": 0, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "None", "ds_from_station": null, "organization_id": "52b7b79b-860c-49a5-9083-9a70cf8bed5a", "ds_serv_man": null, "ds_serv_phone": null, "ds_serv_mail": null, "doi_value": "", "subject_codes": [ "170.1510", "170.4510" ], "quality_level": 0, "publish_time": "2026-09-07 10:13:03", "last_updated": "2026-09-07 10:55:52", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.ncdc.db7777.2026", "i18n": { "en": { "title": "The dataset of monthly surface heat flux at 0.01-degree resolution in the Three River Source Region from 1982 to 2015", "ds_format": "*.nc", "ds_source": "", "ds_quality": "", "ds_ref_way": "", "ds_abstract": "
The surface heat flux (G) is an important part of the land surface energy balance. It reflects the heat transfer between the surface and the soil and the soil energy storage and release process. It is important for understanding the thermal conditions of frozen soil, land-atmosphere interactions and climate change response in alpine regions. It is of great significance. This dataset is based on the published soil temperature data set of 9 layers in the Three‑River Source Region from 1982 to 2015 with a spatial resolution of 0.01°×0.01°, combined with soil moisture and other data, and uses a dynamic soil thermal conductivity parameterization scheme to calculate the surface heat flux caused by soil temperature changes, and further considers the latent heat of phase transition during soil freeze-thawing to obtain monthly surface heat flux (G) data in the Three‑River Source Region area from 1982 to 2015. The spatial resolution of the data is 0.01°×0.01°, and the temporal resolution is monthly in units of W m ². G has positive energy absorption by soil and negative energy release to the atmosphere, which can reflect the seasonal and interannual changes in surface heat input and output in the study area. The results show that the average annual value of G in the Three‑River Source Region from 1982 to 2015 is generally positive, and the regional average is 0.113 W m ², indicating that the soil in the Three‑River Source Region generally absorbs net energy during the study period. G has significant seasonal variation characteristics. The general heat absorption in spring and summer, and the general heat release in autumn and winter. The heat absorption is strong in May and the most obvious in December.", "ds_time_res": "months", "ds_acq_place": "Three‑River Source Region", "ds_space_res": "0.01°×0.01°", "ds_projection": "", "ds_process_way": "", "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, "ds_topic_tags": [ "地表热通量", "冻土热状况", "三江源区" ], "ds_subject_tags": [ "大气物理学", "自然地理学" ], "ds_class_tags": [], "ds_locus_tags": [ "三江源区" ], "ds_time_tags": [ 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 ], "ds_contributors": [ { "true_name": "罗斯琼", "email": "lsq@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "谭晓晴", "email": "t892398232@163.com", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "王景元", "email": "wangjingyuan@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" } ], "ds_meta_authors": [ { "true_name": "谭晓晴", "email": "t892398232@163.com", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "罗斯琼", "email": "lsq@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" } ], "ds_managers": [ { "true_name": "罗斯琼", "email": "lsq@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "谭晓晴", "email": "t892398232@163.com", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" }, { "true_name": "王景元", "email": "wangjingyuan@lzb.ac.cn", "work_for": "中国科学院西北生态环境资源研究院", "country": "中国" } ], "category": "气象" }
