为分析未来甘南地区的气候变化趋势，考虑三种共享社会经济路径下（SSP1-2.6、SSP3-7.0及SSP5-8.5），对CMIP6高分辨率全球环流模式进行筛选，选择对历史数据模拟表现较好的模式，提取未来气候模拟数据，时间跨度采用2021-2080年，经裁剪及降尺度后，提取气温和降水数据，分别分析每种路径下甘南地区气温和降水的变化趋势，结果显示了甘南地区未来时期气温和降水变化趋势的空间分布。\n
该数据集包括2021-2080年SSP1-2.6路径下降水变化趋势、 SSP3-7.0路径下降水变化趋势、SSP5-8.5路径下 降水变化趋势、SSP1-2.6路径下气温变化趋势、SSP3-7.0路径下气温变化趋势、以及SSP5-8.5路径下气温变化趋势，共计6幅，数据类型为栅格格式（.tif）。", "ds_source": "
原始数据来源于CMIP6全球环流模式气候模拟数据，降水数据来自CNRM-CM6-HR模式，气温数据来自ACCESS-CM2模式，社会经济共享路径采用SSP1-2.6、SSP3-7.0及SSP5-8.5三种，时间跨度为2021-2080年。", "ds_process_way": "
经过对ACCESS-CM2、CMCC-CM2-SR5、CNRM-CM6-1-HR、HadGEM3-GC31-MM、MPI-ESM1-2-HR、NorESM2-MM等6个高分辨率全球环流模式历史模拟数据的验证，发现ACCESS-CM2模式下气温表现最好，CNRM-CM6-HR模式下降水表现最好。分别提取两种模式SSP1-2.6、SSP3-7.0及SSP5-8.5三种路径下2021-2080年对应的气温或降水月数据。经降尺度为空间分辨率1 km后，对甘南地区的气温和降水线性变化趋势进行计算。", "ds_quality": "
采用的全球环流模式经过筛选，分别在历史时期气温和降水的模拟中有较好表现，数据计算在Python和Matlab软件中完成，结果较为可靠。", "ds_acq_start_time": "2024-04-01 00:00:00", "ds_acq_end_time": "2024-04-01 00:00:00", "ds_acq_place": "甘南藏族自治州", "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": 5450212, "ds_files_count": 9, "ds_format": "tif", "ds_space_res": "1km", "ds_time_res": "年", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "ec9a812d-3d1a-4c7a-9a96-3b73fd75a4dd.png", "ds_thumb_from": 2, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "c0ec87bd-ed8d-423e-ad11-8dea17bd175d", "ds_serv_man": "敏玉芳", "ds_serv_phone": "0931-4967596", "ds_serv_mail": "ncdc@lzb.ac.cn", "doi_value": "", "subject_codes": [ "170.4510" ], "quality_level": 3, "publish_time": "2024-12-30 17:16:05", "last_updated": "2024-12-31 15:45:01", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.NCDC.NIEER.DB6710.2024", "i18n": { "en": { "title": "Trends of climate change from 2021 to 2080 in Gannan", "ds_format": "", "ds_source": "", "ds_quality": "", "ds_ref_way": "", "ds_abstract": "", "ds_time_res": "年", "ds_acq_place": "Gannan Tibetan Autonomous Prefecture", "ds_space_res": "1km", "ds_projection": "", "ds_process_way": "", "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": [ "气候变化", "气温", "降水", "变化趋势" ], "ds_subject_tags": [ "自然地理学" ], "ds_class_tags": [], "ds_locus_tags": [ "甘南地区" ], "ds_time_tags": [ 2021, 2080 ], "ds_contributors": [ { "true_name": "王宇昕", "email": "wangyuxin@nieer.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": "王宇昕", "email": "wangyuxin@nieer.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": "王宇昕", "email": "wangyuxin@nieer.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" }
