ACE-FTS v4.2 UTLS Climatologies - water vapour & ozone

Zonal-mean ozone and water vapour climatologies generated from the Atmospheric Chemistry Experiment - Fourier Transform Spectrometer (ACE-FTS) version 4.1/4.2 data products. These climatologies are presented in tropopause-relative potential temperature and equivalent latitude coordinates, with the former taken in reference to the 2 PVU dynamical tropopause. The technique used in their generation is described in Jeffery et al. (2022). For each species, one netCDF file is produced for each month, season (3-month), and year, as well as for the multiyear average of each of these. Each file contains the zonal mean, median, standard deviation, median average deviation, maximum, minimum, and number of measurements for each grid cell in the climatology. Additionally, the mean latitude, longitude, local solar time, and tropopause height of each grid cell is included. Version 1.0 of the climatologies covers the period June 2004 to May 2018, and are the replication data for Jeffery et al. (2022).

基于大气化学实验傅里叶变换光谱仪（Atmospheric Chemistry Experiment - Fourier Transform Spectrometer, ACE-FTS）4.1/4.2版数据产品生成的纬向平均臭氧与水汽气候态数据集。该类气候态采用对流层顶相对位温与等效纬度作为坐标体系，其中对流层顶相对位温以2位涡单位（PVU）动力对流层顶为参照基准。其生成方法的详细说明参见Jeffery等（2022）的研究成果。针对每种大气组分，将分别为每个月、每个季节（3个月时段）、每个年份，以及上述各时段的多年平均值生成一个netCDF格式文件。每个文件均包含气候态内各网格单元的纬向均值、中位数、标准差、中位数平均偏差、最大值、最小值以及有效测量样本数。此外，每个网格单元对应的平均纬度、平均经度、当地太阳时与对流层顶高度也将被纳入文件中。该气候态数据集1.0版覆盖2004年6月至2018年5月的时段，为Jeffery等（2022）研究的复现数据集。
