Dataset and simulation code for: Temperature and Pressure Dependent Calibration Transfer Bias of WMS, FWMS, and DAS Methane Retrievals near 1654 nm

Simulated spectra, retrieval results, and Python source code for the manuscript "Temperature and Pressure Dependent Calibration Transfer Bias of WMS, FWMS, and DAS Methane Retrievals near 1654 nm" (M. Guder and I. T. Ozdur, submitted to Sensors). The archive contains the HITRAN2020 CH4 input files, the line-by-line absorption model, the full WMS/FWMS/DAS retrieval implementation, the simulated absorbance spectra for three thermodynamic scenarios, and the scripts that regenerate Figures 10, 12, 14 and 15 of the manuscript.. See README.txt for contents and run instructions.
