Validation of band transfer equations will be conducted in near future by
collecting collocated measurements of multiple sensors. The presented approach
can also be applied to other sensors. In addition, more hyper-spectral sensors, such
as the Infrared Atmospheric Sounding Interferometer (IASI) and Cross-track Infra-
red Sounder (CrIS), can also be used for proxy data simulation and testing database
generation.
