Tropical Pacific SST anomalies generated by a Non-Gaussian Linear Inverse Model (NG-LIM)
收藏资源简介：
Tropical Pacific (20S-20N; 120E-50W) sea surface temperature anomalies (ssta) generated by a "Non-Gaussian Linear Inverse Model" (Martinez-Villalobos et al., manuscript in review; https://essopenarchive.org/users/889305/articles/1266744-a-data-driven-model-of-enso-diversity). The files are: Tropical_Pacific_SSTA_ERSSTv5.nc. Sea surface temperature anomalies calculated from the NOAA Extended Reconstruction SST v5 reanalysis (1948-2022) (Huang et al., 2017). Tropical_Pacific_SSTA_ERSSTv5_10PCs.nc. Same as the previous dataset by filtered only retaining the first 10 SSTA Principal Components and Empirical Orthogonal Functions, accounting for 90% of the SSTA variance over the area of study. Tropical_Pacific_SSTA_LIM.nc. 10,000yr integration of an standard LIM (Penland and Sardeshmukh 1995) trained by dataset 2. Tropical_Pacific_SSTA_LIM.nc. 10,000yr integration of a Non-Gaussian LIM (Martinez-Villalobos et al., in preparation) trained by dataset 2. When using the data please cite https://doi.org/10.5281/zenodo.14775714 (the data) and Martinez-Villalobos et al., in preparation (for the methodology).
