Extended Reconstructed Sea Level Pressure (ERSLP)

The extended reconstructed sea level pressure (ERSLP) analysis was constructed using the most recently available Comprehensive Ocean-Atmosphere Data Set (COADS) SLP data and improved statistical methods that allow stable reconstruction using sparse data. This monthly analysis begins January 1854, however the analyzed signal is heavily damped before 1910 because of sparse data.

扩展重建海平面气压（Extended Reconstructed Sea Level Pressure, ERSLP）分析数据集，采用当前最新可用的综合海洋大气数据集（Comprehensive Ocean-Atmosphere Data Set, COADS）海平面气压（Sea Level Pressure, SLP）数据，并结合改进后的统计方法构建而成，该方法可依托稀疏观测数据实现稳定的重建。该逐月分析的起始时间为1854年1月，但受限于稀疏的观测数据，1910年之前的分析信号存在严重衰减。
