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

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. […]本研究呈现了北极站点新奥尔松（Ny-Ålesund，东经11.9°，北纬78.9°）1993年8月1日至2011年7月31日共计18年的连续气象观测数据集。文中详细阐述了温度、湿度、风速及气压观测所用的仪器配置与数据处理流程。研究展示了全部年份的月均观测值，用以阐明各气象参数的年际变化特征。同时给出了温度、湿度与气压的气候平均值。基于该气候数据集，本研究同时提供了年平均温度与湿度的时间序列，结果表明，在本次研究时段内，温度以每十年1.35 K的速率上升，水汽混合比则以每十年0.22 g/kg的速率增加。随着本观测序列的持续推进，这套新奥尔松高分辨率时间序列数据集将为监测北极气候变化、未来获取趋势性数据提供可靠的数据源……
