There is an international effort to mount a phased argon dark matter program with the goal of being sensitive to the neutrino floor. This effort will include a broad collaboration of scientists and will represent the global community for dark matter searches with argon. The first element of the program is the DarkSide-20k experiment at LNGS, whose science goal is to perform a dark matter search with an exposure of 100 tonne·yr of low-radioactivity underground argon in background-free mode. This detector is designed to be the most sensitive at high WIMPs masses and will be built in time to start data taking by 2021. The second element of the program is ARGO, a low-radioactivity underground argon detector with a fiducial mass of a few hundred tonnes. The science goal is to perform a dark matter search with an exposure of 1,000 tonne·yr, reaching the sensitivity corresponding to the neutrino floor due by the coherent nuclear scattering of atmospheric neutrinos. The CIEMAT-DM group is active in different areas of the experiment, particularly taking a leading role in the detector construction and background assessment. At the same time, thanks also to the synergy with LSC and the mass spectroscopy division at CIEMAT, the group is responsible for the material assay campaign, which is one of the key task for the success of the experiment. The current status of the project and the future plans of the CIEMAT-DM group will be presented in this talk.
