Data collected during SoHO JOP 146, in collaboration with TRACE, is used to investigate the physical characteristics of
coronal active region loops as a function of time and
position along and across loop structures. These data
include TRACE images in all three EUV passbands, and
simultaneous CDS spectroscopic observations. Preliminary
measurements of the loop temperature both along the loop
half-length and loop cross-section are presented as a
function of time. We will show the temperature and
density profiles of several structures as a function
of position, show changes in temperature and density with
time and characterize the coronal background emission.
Questions raised by these results will be greatly advanced
with the high resolution spectra available from the
EIS on Solar-B.
