Coefficient Fitting Code and Plotting Scripts for COCTS2 Calibration in

This dataset provides the supporting code and data for the paper "Advanced Radiometric Cross-Calibration of HY-1E/COCTS2 Thermal Infrared Bands Using MetOp-C/IASI".Contents: This dataset includes the coefficient fitting code used for COCTS2 calibration, the corresponding plotting scripts, and the desensitized intermediate data used to validate the fitting results.Data Availability and Restrictions: Due to data security and confidentiality policies, the raw L1A data used in this study cannot be made publicly available.

Additionally, the data matching program used for preprocessing is deeply integrated and deployed within the official ground station system; due to system architecture and intellectual property protections, this program cannot be open-sourced.Despite the restrictions on the raw data and matching program, the fitting code and plotting scripts provided in this dataset allow for the full reproduction of the core calibration parameter calculations and figure generation presented in the paper.
