Interagency report: Global and Regional Sea Level Rise Scenarios for the United States: Updated Mean Projections and Extreme Water Level Probabilities Along U.S. Coastlines

Code and data for Section 2 of the Interagency report: Global and Regional Sea Level Rise Scenarios for the United States: Updated Mean Projections and Extreme Water Level Probabilities Along U.S. Coastlines Versions: Version 1.1 This one: updated region names Version 1.0 https://doi.org/10.5281/zenodo.5951626 This repository contains the code and data needed to produce the trajectories, projections, and observations for the Interagency report: Global and Regional Sea Level Rise Scenarios for the United States: Updated Mean Projections and Extreme Water Level Probabilities Along U.S. Coastlines. The report can be found on https://oceanservice.noaa.gov/hazards/sealevelrise/sealevelrise-tech-report-sections.html An interactive tool to study the observations, trajectories, and scenarios can be accessed from https://sealevel.nasa.gov/task-force-scenario-tool Frequently-asked questions: https://sealevel.nasa.gov/faq/16/ Authors William V.

Veatch, U.S. Army Corps of Engineers Kathleen D. White, U.S. Department of Defense Casey Zuzak, FEMA Risk Management Directorate Contents This data and code set contains the following directories: Results The Results folder contains the resulting projections, trajectories and observations from the report. TR_global_projections.nc: GMSL projections, trajectory, and observations TR_regional_projections.nc: Regional observations, projections and trajectories TR_local_projections.nc: Local observations, projections and trajectories TR_gridded_projections.nc: Gridded projections These files are in the NetCDF forrmat. To read the NetCDF files, many free software packages are available, including ncview and Panoply. Free NetCDF packages are available to directly import the data into Julia and Python code. Code The Code folder contains all the computer code used to read and analyze the observations and the projections, and to generate the trajectories. To run this code, you need Julia. The code requires the Julia packages CSV, Interpolations, JSON, LoopVectorization, MAT, NCDatasets, NetCDF, Plots, XLSX, LinearAlgebra, and Statistics. They can be installed by pressing ] at the Julia REPL and typing:

add CSV Interpolations JSON LoopVectorization MAT NCDatasets NetCDF Plots XLSX LinearAlgebra Statistics 

This program also requires Hector. Hector needs to be installed or compiled. In the file Hector.jl update the path to the Hector executable on lines 30 and 104. Run Run_TR.jl in the REPL or run julia Run_TR.jl from the command line to run the projections. The projections are then written to the .\Data directory. The folder contains the following files: Run_TR.jl: This is the main routine that (eventually) calls all the functions to compute the projections. ConvertNCA5ToGrid.jl: Converts the original NCA5 projections to a set of netCDF files that's used throughout this code ProcessObservations.jl: Reads and processes the tide-gauge and altimetry observations GlobalProjections.jl: Reads and processes the GMSL observations and projections, and computes the trajectory RegionalProjections.jl: Reads and processes the regional projections and computes the trajectories LocalProjections.jl: Reads and processes the local projections at the tide-gauge locations and computes the trajectories GriddedProjections.jl: Reads the gridded NCA5 projections and add a GMSL baseline correction for the 2005 vs 2000 baseline SaveFigureData.jl: Reads the results and writes text files for GMT Hector.jl: Wrapper for Hector, used to compute trends and uncertainties. <code>Masks.jl< ...
