Precipitation measurements from Automatic Weather Station (AWS) at Freiburg – Chemiehochhaus (FRCHEM) from 2022-01-01 to 2022-12-31 [L2]

Quality controlled and gap-filled continuous precipitation measurements from the urban rooftop weather station at Freiburg-Chemiehochhaus (FRCHEM, 7.8486ºE, 48.0011ºN, 323.5 m) using a tipping bucket raingauge (SBS500H tipping bucket, Campbell Scientific Inc., Logan UT, USA, resolution 0.2 mm per tip) with internal heaters operated at roof level. Quality controlled above-canopy precipitation data are available and aggregated at 10min, 30min, hourly, daily, monthly and yearly resolution for the year 2022. Precipitation sums are provided on hourly, daily, monthly and annual scales. Number of hours with precipitation >0.1 mm/hr, >1 mm/hr, >2.5 mm/hr, >5 mm/hr, >10 mm/hr, >20 mm/hr, and > 50 mm/hr provided on daily, monthly, and annual scale. Number of days with precipitation >0.1 mm/day, >1 mm/day, >2.5 mm/day, >5 mm/day, >10 mm/day, >20 mm/day and >50 mm/day provided on monthly, and annual scale. Precipitation does not distinguish between form (e.g. snow vs. rain) Detailed information on gap-filled data is provided. Note: All times are provided in UTC, not local time. For more details read `FRCHEM_2022_Precipitation_MetaData.txt`. Version 1.1 corrects an error in the time-axis of the file "..._Precipitation_10_min_UTC.csv", where previously the file would only contain reasonable values until August-15, 23:50. Other files were unaffected by this. displays times according to ISO 8610 to unambiguously identify that all times are given in UTC. Further, the column headers for the time periods have been changed to "From" and "To" to indicate the start and end of the aggregation periods.本数据集包含来自弗赖堡化学大厦（Freiburg-Chemiehochhaus，简称FRCHEM，地理坐标为7.8486°E、48.0011°N，海拔323.5米）城市屋顶气象站的经质量控制且已完成缺失值填补的连续降水观测数据。观测采用翻斗式雨量计（tipping bucket raingauge，型号SBS500H，由美国犹他州洛根市Campbell Scientific Inc.生产，每翻斗分辨率为0.2毫米），并在屋顶层面加装内置加热装置。 已获取冠层上方降水的质控数据集，并将其聚合为2022年的10分钟、30分钟、小时、日、月及年尺度的统计数据。 数据集提供小时、日、月及年尺度的降水总量统计值。 提供日、月、年尺度下，小时降水量大于0.1 mm/hr、1 mm/hr、2.5 mm/hr、5 mm/hr、10 mm/hr、20 mm/hr及50 mm/hr的小时数统计结果。 提供月、年尺度下，日降水量大于0.1 mm/day、1 mm/day、2.5 mm/day、5 mm/day、10 mm/day、20 mm/day及50 mm/day的天数统计结果。 本数据集未区分降水形态（如雪与降雨）。 已提供缺失值填补的详细说明信息。 注：所有时间均采用协调世界时（UTC），而非当地时间。 更多详情请参阅`FRCHEM_2022_Precipitation_MetaData.txt`文件。 版本1.1 本次更新修正了`..._Precipitation_10_min_UTC.csv`文件的时间轴错误——此前该文件仅在2022年8月15日23:50前包含有效数据，其余文件未受此问题影响。 本数据集采用ISO 8610标准格式化时间，以明确所有时间均采用协调世界时（UTC）标注。此外，时段列的表头已调整为From与To，用于指示聚合时段的起始与结束时刻。
