Ocean Heat Content (OHC) anomalies for 1950 to 2003

This data file contains Ocean heat content (OHC) anomalies and associated errors between 1950 and 2003, based on the enact 3 data set with Wijffels et.al. (2008) fall rate corrections applied to the eXpendable BathyThermograph (XBT). There are two files, one with yearly averages, the other with three-year running means. The Units are: Joules X 1e-22 (i.e. multiply the numbers in the file by 1e22 to get OHC in Joules). For the errors, One-sigma error in the same units as the variables. and the period is 1950 to 2003, relative to 1961 (zero-crossing), the yearly averages are averages over a calendar year. The time in the file is the centre of the year averaged over. Three-year means are also centred on the time shown. and the depth-integrations are 0-100 m, 0-300 m, and 0-700 m. The three-year running means are as plotted in Domingues et.al. (2008), and are recommended as being the best to use.

本数据集包含1950年至2003年间的海洋热含量（Ocean Heat Content, OHC）异常值及相关误差，其基于enact 3数据集，并针对投弃式温深仪（eXpendable BathyThermograph, XBT）应用了Wijffels等人（2008）提出的落速校正方法。
本数据集包含两个文件：其一为逐年平均值数据，其二为三年滑动平均值数据。
单位为：焦耳×10^-22（即需将文件中的数值乘以10^22，即可得到以焦耳为单位的海洋热含量）。
误差项为单西格玛（One-sigma）误差，其单位与变量一致。本次数据集的时间跨度为1950年至2003年，以1961年为基准（该年份对应零交叉点）；逐年平均值为对应自然年内的平均结果。
文件中记录的时间为对应逐年平均的年份中点；三年滑动平均值的时间中心与文件标注的时间一致。
积分深度范围分别为0-100米、0-300米及0-700米。
三年滑动平均值数据与Domingues等人（2008）中绘制的结果一致，该数据集被推荐为最优选用版本。
