   In spite that the Galactic diffuse X-ray emission is the most
   energetic constituent in the interstellar space, its origin, probably
   diffuse in nature, is still unknown. ASCA spectra exhibited numerous
   emission lines expected from thermal plasmas, and more importantly,
   there was an indication that the plasma becomes cooler going far from
   the Galactic plane. This suggests the thermal plasma is dynamic and
   continuously outflowing from the Galactic plane. We propose three
   pointings at l=0 toward the positive latitudinal direction, where we
   will carry out scanning observations with XTE. By combining ASCA and
   XTE data, we will study spectral variations parpendicular to the
   Galactic plane.
