AB: Measurements of coronal and chromospheric magnetic fields are arguably the most important observables required for advances in our understanding of the emergence of magnetic flux into the solar atmosphere and the processes responsible for the production of solar activity, coronal heating and coronal dynamics. The COronal Solar Magnetism Observatory (COSMO) is a proposed ground-based suite of instruments designed for routine study of coronal and chromospheric magnetic fields and their environment. The facility consists of 3 instruments: 1) a meter-class aperture coronal magnetometer devoted to obtaining the highest quality polarimetric data of forbidden lines of Fe XIII 1074.7 and 1079.8 nm.; 2) a chromosphere and prominence magnetometer devoted primarily to measurements of lines of helium (D3, 1083 nm) and perhaps Halpha, that will provide full disk vector magnetic field observations; 3) a white-light polarized-brightness (pB) coronagraph that will observe down to 1.05 solar radii at very high time cadence (15 seconds) at high signal-to-noise. This new facility will be operated by the High Altitude Observatory of the National Center for Atmospheric Research (HAO/NCAR) in collaboration with the University of Hawaii and the University of Michigan. COSMO will enhance the value of existing and new observatories on the ground (SOLIS, ATST, and FASR) and in space (SOHO, TRACE, GOES, SOLAR-B, STEREO, SDO) by providing unique and crucial observations of the global coronal and chromospheric magnetic field and its evolution.
