包头气象站位于内蒙古自治区包头市，地理位置坐标为：东经109.53°，北纬40.32°，场址海拔1078m，观测项目有气温、降雨、湿度、风速、冰冻等。本数据集为包头气象站1954-2018年凌汛期逐日平均气温观测数据，经统计分析计算出该站历年累计负气温。本数据集共包含1 个excel文件，共两列，1列为年份，1列为年累计负气温。", "ds_source": "
该数据集数据全部为气象站观测数据经统计分析计算后的数据，气温资料严格按照国家气象局地面气象观测规范要求进行观测，观测时间为每日2时、8时、14时、20日；地表温度采用地面最高和最低温度表观测，土壤温度采用曲管地温表和直管地温表观测；源数据日气温资料来源于每年刊印的气象统计年鉴，购买自包头市气象局。", "ds_process_way": "
累计负气温是表征气候条件的一个重要指标，一般累计负气温越小表示越严寒。其计算方法是：自凌汛期气温稳定转负起到气温稳定转正结束，将日平均负气温逐日累计而得。", "ds_quality": "
日气温数据为气象站专业人员测量，经校核整编后正式刊印，累计负气温计算是专业技术人员计算并经校审、审核后采用。", "ds_acq_start_time": "1954-11-01 00:00:00", "ds_acq_end_time": "2018-03-31 00:00:00", "ds_acq_place": "内蒙古包头气象站", "ds_acq_lon_east": 109.53, "ds_acq_lat_south": 40.32, "ds_acq_lon_west": 109.53, "ds_acq_lat_north": 40.32, "ds_acq_alt_low": 1060.0, "ds_acq_alt_high": 1078.0, "ds_share_type": "login-access", "ds_total_size": 41657, "ds_files_count": 3, "ds_format": "excel", "ds_space_res": null, "ds_time_res": "日", "ds_coordinate": "无", "ds_projection": "", "ds_thumbnail": "ca93cdf2-8c25-40fa-ad11-58bd02dd7d6a.png", "ds_thumb_from": 0, "ds_ref_way": "", "paper_ref_way": "", "ds_ref_instruction": "", "ds_from_station": null, "organization_id": "c55e1118-387b-4a0c-8dc5-70aa438c430d", "ds_serv_man": "李红星", "ds_serv_phone": "0931-4967592", "ds_serv_mail": "ncdc@lzb.ac.cn", "doi_value": "10.12072/ncdc.iceflood.db2374.2022", "subject_codes": [ "170.55" ], "quality_level": 3, "publish_time": "2022-07-30 15:46:52", "last_updated": "2025-06-30 15:58:58", "protected": false, "protected_to": null, "lang": "zh", "cstr": "11738.11.ncdc.iceflood.db2374.2022", "i18n": { "en": { "title": "Data set of accumulated negative air temperature in ice flood season at Baotou meteorological station (1954-2018)", "ds_format": "excel", "ds_source": "
The data in this data set are all the data from the observation data of the meteorological station after statistical analysis and calculation.

Baotou meteorological station is located in Baotou City, Inner Mongolia Autonomous Region. The geographical coordinates are 109.53 ° east longitude, 40.32 ° north latitude, and the altitude of the site is 1078m. The observation items include temperature, rainfall, humidity, wind speed, freezing, etc. This data set is the daily average temperature observation data of Baotou meteorological station during the ice flood season from 1954 to 2018. Through statistical analysis, the cumulative negative temperature of the station over the years is calculated. This data set contains an excel file with two columns, one is the year and the other is the cumulative negative temperature of the year.
