Launching in 2028, ESA's Atmospheric Remote-sensing Exoplanet Large-survey(ARIEL) survey of $\sim$1000 transiting exoplanets will build on the legaciesof Kepler and TESS and complement JWST by placing its high precision exoplanetobservations into a large, statistically-significant planetary populationcontext. With continuous 0.5--7.8~$\mu$m coverage from both FGS (0.50--0.55,0.8--1.0, and 1.0--1.2~$\mu$m photometry; 1.25--1.95~$\mu$m spectroscopy) andAIRS (1.95--7.80~$\mu$m spectroscopy), ARIEL will determine atmosphericcompositions and probe planetary formation histories during its 3.5-yearmission. NASA's proposed Contribution to ARIEL Spectroscopy of Exoplanets(CASE) would be a subsystem of ARIEL's FGS instrument consisting of twovisible-to-infrared detectors, associated readout electronics, and thermalcontrol hardware. FGS, to be built by the Polish Academy of Sciences' SpaceResearch Centre, will provide both fine guiding and visible to near-infraredphotometry and spectroscopy, providing powerful diagnostics of atmosphericaerosol contribution and planetary albedo, which play a crucial role inestablishing planetary energy balance. The CASE team presents here anindependent study of the capabilities of ARIEL to measure exoplanetarymetallicities, which probe the conditions of planet formation, and FGS tomeasure scattering spectral slopes, which indicate if an exoplanet hasatmospheric aerosols (clouds and hazes), and geometric albedos, which helpestablish planetary climate. Our design reference mission simulations show thatARIEL could measure the mass-metallicity relationship of its 1000-planetsingle-visit sample to $>7.5\sigma$ and that FGS could distinguish betweenclear, cloudy, and hazy skies and constrain an exoplanet's atmospheric aerosolcomposition to $>5\sigma$ for hundreds of targets, providingstatistically-transformative science for exoplanet atmospheres.
