The goal of this research study is to understand the sensitivity of the IT region to the spatial variation of Kzz. This is done using the IT model, GITM, with different settings and spatial distributions for Kzz. We introduce latitudinal bands (longitudinally uniform) of 30 degrees width at equatorial and polar latitudes during different seasons similar to the previous observations in literature. We investigate the mechanisms through which a non-uniform global distribution of Kzz can alter the dynamics and thermal structure of the thermosphere, and how these effects compare to when a globally uniform value of Kzz is used.

This research was completed to statistically validate that a data-model refinement technique could integrate real measurements to remove bias from physics-based models via changing the forcing parameters such as the thermal conductivity coefficients.
