Air temperature 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 air temperature data from the urban rooftop weather station at Freiburg-Chemiehochhaus (FRCHEM, 7.8486ºE, 48.0011ºN, 323.5 m) using an actively ventillated and shielded psychrometer operated 2m above roof level.

Quality controlled air temperature data are available and aggregated at 10min, 30min, hourly, daily, monthly and yearly resolution for the year 2022.

Average, minimum and maximum air temperatures are provided on hourly, daily, monthly and annual scales.

Characteristic hours and days are reported on daily, monthly and annual scales (e.g. summer days with T_max > 25ºC, hot days with T_max > 30º, desert days with T_max > 35ºC, tropical nights with T_min > 20°, frost days with T_min < 0ºC and ice days with T_max < 0ºC, all based on 00:00 - 24:00 UTC).

Detailed information on gap-filled data is provided.

Note: All times are provided in UTC, not local time.

Version 1.1.0 contains additionally air temperature data aggregated at 10min and 30min.

本数据集包含来自弗莱堡化工大厦（Freiburg-Chemiehochhaus，简称FRCHEM，经度7.8486°E，纬度48.0011°N，海拔323.5米）城市屋顶气象站的经质量控制与间隙填充的连续气温数据，该站点采用安装于屋顶上方2米处的主动通风屏蔽式干湿表进行观测。

2022年的经质量控制气温数据已按10分钟、30分钟、逐小时、逐日、逐月及逐年的时间分辨率进行聚合并提供。

数据集提供逐小时、逐日、逐月及逐年尺度下的平均、最低与最高气温数据。

数据集按逐日、逐月及逐年尺度统计并报告特征时刻与特征日（例如日最高温大于25℃的夏日、日最高温大于30℃的酷热日、日最高温大于35℃的荒漠日、日最低温大于20℃的热带夜、日最低温小于0℃的霜日以及日最高温小于0℃的冰日，所有统计均基于UTC时间00:00至24:00）。

数据集还提供了间隙填充数据的详细说明。

注意：所有时间均采用UTC时间，而非当地时间。

1.1.0版本额外新增了按10分钟与30分钟分辨率聚合的气温数据。
