Feasibility of reconstructing the basin-scale sea surface partial pressure of carbon dioxide from sparse in situ observations over the South China Sea

Descrption of the repository

This repo contains replication codes for graphs and other supplementary documentation for Wang et al.

Data and data treatment

Underway sea surface pCO2 data from 35 cruises ranging from 2000-2017 were compiled in this study. Observed sea surface pCO2 in the SCS is mainly distributed on the northern shelf and in the northern basin. Since monthly data are hardly available for each year starting from 2000, we have compiled the data seasonally in which the spring season includes March-May, the summer season is June-August, the fall season is September-November, and the winter season includes December and the next January and February.

Contents for R codes

Each R code can be run individully. Before running the code, all data files need to be under the same working directory as R locally. Use getwd() to check the current working directory and use setwd(dir) to change it. The code pCO2_analysis_figures.R produces all analysis and figures is also included.

  • The code SummerOB.R replicates Figure 3.
  • The code SummerRS.R replicates Figure 4.
  • The code ModeNumber.R replicates Figure 5.
  • The code SummerRSEOFs.R replicates Figure 6(a)(b)(c).
  • The code RS_PCs.R replicates Figure 6(d).
  • The code Reconstrcuted_pCO2.R replicates the reconstruction implementation and Figure 7 mentioned in the paper.
  • The code Reconstructed_TS.R replicates Figure 8.
