Data and script for: An Improved Thermal Infrared Sea Ice Concentration Retrieval Algorithm

OverviewThis repository contains the information for the paper “An Improved Thermal Infrared Sea Ice Concentration Retrieval Algorithm”.Author: Xin WangContact: [e-mail]: MATLAB 2024bLast Updated: March 2026DataRelevant data used in this study is provided as follows:• GeoData.zip - Geographic coordinate data corresponding to IMPA SIC daily composite data (including latitude/longitude).• IMPA_SIC_Daily.zip - Daily composite IMPA Sea Ice Concentration (SIC) data for January to May 2019.ScriptsThis repository contains MATLAB scripts for:• Visual.m – Read and visualize daily composite IMPA SIC data.• FuncMapShow_NP_IMPA.m – Core mapping function called by Visual.m.All scripts were developed and tested in MATLAB 2024b.Script Usage Steps:1. Unzip both GeoData.zip and IMPA_SIC_Daily.zip, then place all extracted files (including the GeoData/ folder and files from IMPA_SIC_Daily.zip) in the same directory as the MATLAB scripts.2. Install the m_map toolbox (download from https://www-old.eoas.ubc.ca/~rich/map.html).3. Open MATLAB 2024b, set the working directory to the script folder, and run Visual.m (modify the data directory and the date to be visualized).
