Title: *Francis X Kneizys: Pioneering Atmospheric Modelling*

Introduction

Francis X Kneizys is a notable inventor based in Burlington, Massachusetts, who has made significant contributions to the field of atmospheric modelling. With two patents to his name, he has focused on developing advanced computer codes that predict atmospheric transmittance and background radiance across various spectral regions.

Latest Patents

His latest patents include the "System for modelling moderate resolution atmospheric propagation," known as MODTRAN. This moderate resolution model is essential for predicting atmospheric transmittance and background radiance in the microwave, infrared, visible, and near ultraviolet spectral regions. MODTRAN enhances the spectral resolution from the previous LOWTRAN 7 model, improving it from 20 to 2 cm^-1 full width/half maximum (fwhm). It also retains compatibility with LOWTRAN 7, preserving all its capabilities while introducing enhancements like varying resolution options and improved molecular band model parameters derived from the HITRAN line atlas for various atmospheric gases.

Another significant contribution is the "System for modelling low resolution atmospheric propagation," titled LOWTRAN 7. This low-resolution propagation model builds on the earlier LOWTRAN 6 (1983) model and provides predictions for atmospheric transmittance and background radiance at a resolution of 20 cm^-1. This version includes new parameters for multiple scattered radiation, updated cloud models, and enhanced atmospheric models that consider geographical and seasonal variations.
