The Open Clusters Chemical Abundances from Spanish Observatories survey (OCCASO) aims to obtaining high-resolution spectra (R<65,000) in the optical range (500-800 nm) for Red Clump (RC) stars in Northern hemisphere OCs. This survey systematically targets OCs with at least six RC stars per cluster, with a signal-to-noise around 70. It was designed to obtain precise radial velocities and detailed chemical abundances in OCs to analyze their kinematics and chemical trends in the Galactic disk.

The WEAVE (WHT Enhanced Area Velocity Explorer) Galactic survey aims to determine chemical abundances and radial velocities for several million of stars complementing the Gaia mission.
