Continuous meteorological observations at station Ny-Ålesund, 1993-08 to 2011-07

A consistent meteorological dataset of the Arctic site Ny-Ålesund (11.9° E, 78.9° N) spanning the 18 yr-period 1 August 1993 to 31 July 2011 is presented. Instrumentation and data handling of temperature, humidity, wind and pressure measurements are described in detail. Monthly mean values are shown for all years to illustrate the interannual variability of the different parameters. Climatological mean values are given for temperature, humidity and pressure. From the climatological dataset, we also present the time series of annual mean temperature and humidity, revealing a temperature increase of +1.35 K per decade and an increase in water vapor mixing ratio of +0.22 g/kg per decade for the given time period, respectively. With the continuation of the presented measurements, the Ny-Ålesund high resolution time series will provide a reliable source to monitor Arctic change and retrieve trends in the future. […]

本报告呈现了覆盖自1993年8月1日至2011年7月31日长达18年之久的北极地区Ny-Ålesund（经度11.9° E，纬度78.9° N）气象数据集。详细描述了温度、湿度、风速和气压测量所使用的仪器和数据处理方法。为展示不同参数的年际变化，展示了所有年份的月平均值。提供了温度、湿度和气压的气候平均值。从气候数据集中，我们还展示了年度平均温度和湿度的时序数据，揭示了在该时间段内温度每十年上升1.35 K，水汽混合比每十年增加0.22 g/kg。随着所呈现测量的持续进行，Ny-Ålesund高分辨率时间序列将为监测北极变化和获取未来趋势提供可靠的数据来源。（气象数据集，Ny-Ålesund，温度，湿度，风速，气压，气候数据，时序数据，北极变化，趋势）
