What is it about?
Different fitting function can be applied to the radiometric calibration. To select the optimized function, we have investigated linear equation and semi-nonlinear equation for thermal emission band.

Why is it important?
The judgement criteria of calibration algorithm should be that whether the calibration results can reflect sensors inherent propertities or not. The proper function can improve the calibration accuracy and satellite data quality.
Perspectives
I hope this article can improve satellite data quality and make the earth observation data be used effciently.
