Infrared remote sensing technique has been widely used for the characteristics of objects since it
has the advantage of higher atmospheric transmittance than visible wavelengths. However, the
Mid-Wave InfraRed (MWIR) region close to the visible band can be partially affected by solar
radiation, so the solar radiation and attenuation in the atmosphere cause errors in the target
detecting. In this study, an algorithm for retrieval of the mid-infrared surface temperature was
developed by using a combination of the GEO-KOMPSAT-2A (GK-2A) satellite and Landsat data.
Through the comparison with ground observations, it was found that the surface temperatures at
MWIR band retrieved are less than 3K, and a statistically significant level of mutual comparison
was obtained. Therefore, despite the limitations of the MWIR band, the new methodology can be
applied to determine the surface-level temperature through the coupling between the two
different orbit satellites.
