I sent the following from a "wrong" From address!  Here, the same links
once again plus a shell script.

Importing and converting to digital numbers to radiance values, are
the basics.  The rest of the steps, of "your" interest, I guess can be
achieved with GRASS' multiple raster and imagery related modules.

Haven't used it for a while, but there is
https://grass.osgeo.org/grass70/manuals/r.in.aster.html.

As well, https://grass.osgeo.org/grass70/manuals/i.aster.toar.html.

For the latter, however, as I had some problem (in the past) I used a
shell script: https://grasswiki.osgeo.org/wiki/User:NikosA#ASTER_L1B
