  The Global Magneto-Ionic Medium Survey (GMIMS) is a project to map the
diffuse polarized emission over the entire sky, Northern and Southern
hemispheres, from 300 MHz to 1.8 GHz. With an angular resolution of 30 - 60
arcmin and a frequency resolution of 1 MHz or better, GMIMS will provide the
first spectro-polarimetric data set of the large-scale polarized emission over
the entire sky, observed with single-dish telescopes. GMIMS will provide an
invaluable resource for studies of the magneto-ionic medium of the Galaxy in
the local disk, halo, and its transition.
