云顶滑雪场为2022年北京冬奥会重要比赛场地之一。本数据集所包含数据取自云顶滑雪场训练赛道特定剖面（经纬度约为115°25′11″ E，40°57′27″ N），剖面全长约40m，每10m分布一观测点。观测时段包括2021年1月10日至4月6日及2021年12月2日至12月31日。观测仪器采用ASD FieldSpec® HandHeld™ 2 便携式分光辐射谱仪。本数据集共包含2个文件夹（分别对应两个时段），2964个.asd文件，针对单点的一次观测值对应一个.asd文件。.asd文件包含波长325-1075nm范围内反照率曲线信息。", "ds_source": "
该数据集数据全部为人工观测数据，严格按照ASD FieldSpec® HandHeld™ 2 便携式分光辐射谱仪观测规范要求进行观测。观测频率每日两次，时间为每日8:00-9:00及16:00-17:00。", "ds_process_way": "
通过ASD FieldSpec® HandHeld™ 2 便携式分光辐射谱仪观测数据后，使用HH2 Sync应用程序，将HandHeld 2 采集的光谱数据文件导入到外部电脑中即为本数据集中.asd文件。", "ds_quality": "
观测人员为相关专业技术人员，并且经过天山冰川站专业人员培训，观测过程规范，观测数据可靠，数据质量良好。", "ds_acq_start_time": "2021-01-10 00:00:00", "ds_acq_end_time": "2021-04-06 00:00:00", "ds_acq_place": "云顶滑雪场训练赛道特定剖面", "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": 37132452, "ds_files_count": 2966, "ds_format": "asd", "ds_space_res": null, "ds_time_res": "日", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "71c72075-1c31-4b24-b57b-9ddd17ddc014.png", "ds_thumb_from": 2, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "52f86cb3-7bfa-4b4b-ae86-0e38af374716", "ds_serv_man": "李红星", "ds_serv_phone": "0931-4967592", "ds_serv_mail": "ncdc@lzb.ac.cn", "doi_value": "", "subject_codes": [ "170.45" ], "quality_level": 3, "publish_time": "2023-07-10 10:43:35", "last_updated": "2023-07-15 02:10:03", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.NCDC.T-SNOW.DB2888.2023", "i18n": { "en": { "title": "Daily observation data set of Albedo on the track surface of Yunding Ski Resort in Zhangjiakou Winter Olympics (2021)", "ds_format": "", "ds_source": "", "ds_quality": "", "ds_ref_way": "", "ds_abstract": "", "ds_time_res": "日", "ds_acq_place": "Yunding Ski Resort Training Track Specific Profile", "ds_space_res": "", "ds_projection": "", "ds_process_way": "", "ds_ref_instruction": "" } }, "submit_center_id": "ncdc", "data_level": 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, "ds_topic_tags": [ "雪表面反照率", "云顶滑雪场", "剖面" ], "ds_subject_tags": [ "地理学" ], "ds_class_tags": [], "ds_locus_tags": [ "崇礼", "云顶滑雪场" ], "ds_time_tags": [ 2021 ], "ds_contributors": [ { "true_name": "李慧林", "email": "lihuilin@lzb.ac.cn", "work_for": "天山冰川观测实验站", "country": "" } ], "ds_meta_authors": [ { "true_name": "李慧林", "email": "lihuilin@lzb.ac.cn", "work_for": "天山冰川观测实验站", "country": "" } ], "ds_managers": [ { "true_name": "李慧林", "email": "lihuilin@lzb.ac.cn", "work_for": "天山冰川观测实验站", "country": "" } ], "category": "积雪" }
