After calculating the emissivity values for ASTER thermal bands using Temperature-Emissivity Separation(TES) algorithm some sub-horizontal noises are appearing in the image. Are they the scan line noises of ASTER thermal scanner? If it is so, how to remove those noises?

ASTER TIR bands have a known scan line issue that is described on the ASTER Science Project website: http://www.science.aster.ersdac.jspac... They perform a correction but it has some errors which is probably what you are seeing. You might try the THOR Destriping tool to remove additional noise.
