We propose an M-band magnitude-limited survey of CO and H2O gas in Protoplanetary Disks observable with iSHELL from Mauna Kea [down to M~5.5 mag], to provide a high-quality spectral database with strong and lasting value to the community. We use iSHELL with its high-resolution slits [0.375' and 0.75'] to cover M-band [4.52-5.25 um] ro-vibrational emission from inner disk CO and H2O in targets visible in this semester. This program complements data that has already been obtained with iSHELL in previous semesters toward building a total sample of ~100 disks, and will provide a spectrally-complete, homogeneous dataset at high spectral resolution and high signal-to-noise. The survey fully-reduced science-ready spectra are available to the community through a public online database. This dataset is enabling multiple investigations crossing fields of disks, winds, and exoplanets, to study the structure, kinematics, chemistry, and evolution of the inner 10 au in Protoplanetary Disks around stars of mass > 0.5 Msol. This program complements and supports extensive campaigns that are observing these disks at optical, infrared, and millimeter wavelengths, including infrared spectra from JWST in Cycle 1.
