We have to mosaic 70+ ASTER Level 1T imageries. I've splitted hdf data into 14 different tif's (3 VNIR, 6 SWIR, 5 TIR). As shown in the image imageries are of different time period.

Question is, is it possible to do radiometric correction in QGIS or SAGA ? I know SCP plugin has a module wherein which we can do atmospehric correction. But if i load the hdf file pixel values were getting changed and instead of 14 images, 32 images are being listed out.

Is there any alternatives ? And since number of imageries are huge, like to do it in bulk - batch mode
