I have already download daily data from Global Ocean Gridded L 4 Sea Surface Heights And Derived Variables Reprocessed Copernicus Climate Service. The daily data in December 2022 downloaded from this link (https://data.marine.copernicus.eu/product/SEALEVEL_GLO_PHY_CLIMATE_L4_MY_008_057/files?path=SEALEVEL_GLO_PHY_CLIMATE_L4_MY_008_057%2Fc3s_obs-sl_glo_phy-ssh_my_twosat-l4-duacs-0.25deg_P1D_202112%2F2022%2F12%2F&subdataset=c3s_obs-sl_glo_phy-ssh_my_twosat-l4-duacs-0.25deg_P1D_202112). Actually I want merger all data in a file Dec2022. The size matrix data from 1440x720x1 become 1440x720x31. From data I can calculate mean monthly data from daily. The same logic finally I can merger data monthly on 2022 with a size matrix 1440x720x12 (jan to dec).
Thank you

Load each file indiviudally, extract the variable you want, and use the cat function to concatenate each one along the 3rd dimension.
