In this work, we develop an exospheric temperature model based in machine learning (ML) that can be used with NRLMSIS 2. 0 to calibrate it relative to high-fidelity satellite density estimates.

Machine learning (ML) is often viewed as a black-box regression technique that is unable to provide considerable scientific insight.

These models leverage Monte Carlo (MC) dropout to provide uncertainty estimates, and the use of the NLPD loss function results in well-calibrated uncertainty estimates without sacrificing model accuracy (<10% mean absolute error).
