Regional weighted means of groundbased ozone (O3) anomalies timeseries in the Arctic, 2000-2024

Total and partial columns of ozone (O3) relative anomalies created by averaging with a weighted mean ozone relative anomalies timeseries of different groundbased instruments in the Arctic region (60-90°N) for the 2000-2024 time period.

Types of instruments used: Brewer and Dobson spectrophotometers from WOUDC (https://woudc.org/en/data/data-search-and-download) for the total column of ozone only, FTIR spectrometers from NDACC (https://ndacc.larc.nasa.gov/) for all columns and ozonesondes from HEGIFTOM (https://hegiftom.meteo.be/datasets/ozonesondes) for the troposphere, lower and mid stratosphere.
Each individual dataset used to create the present merged datasets are under the responsibility of their respective PIs.
Further details on how the merged datasets are obtained (i.e., definition of regions, list of instruments merged for each timeseries, anomalies calculation, weighting calculation, trends calculated from these columns, etc.) are given in https://doi.org/10.5194/egusphere-2025-6473.

本数据集包含2000年至2024年北极地区（北纬60°至90°）的臭氧（O₃）总量与分量相对异常值，通过对不同地基仪器的臭氧相对异常时间序列进行加权平均计算得到。
所用仪器类型如下：仅用于臭氧总量观测的世界臭氧与紫外辐射数据中心（WOUDC，https://woudc.org/en/data/data-search-and-download）的布鲁尔（Brewer）与多布森（Dobson）分光光度计；可覆盖所有臭氧分量观测的大气成分变化监测网络（NDACC，https://ndacc.larc.nasa.gov/）的傅里叶变换红外（FTIR）光谱仪；以及用于对流层、平流层低层与中层观测的HEGIFTOM臭氧探空仪（https://hegiftom.meteo.be/datasets/ozonesondes）。
本合并数据集所采用的各原始数据集，其责任均由各自的首席研究员（Principal Investigators，PIs）承担。
