There is SRTM 1 arcsec (that is approx. 30m) global data (land between parallels 60N and 60S respectively) available to download from https://earthexplorer.usgs.gov/. Just click the location, follow to the another tab "Data Sets" and locate Digital Elevation -> SRTM -> SRTM 1 Arc-Second Global. Proceed to "Results" tab and follow the "Download" icon.
You can download the Alos Palsar data. The DEMs have a resolution of 12.5 m derived from SAR with a date until 2011. You can enter by this link https://vertex.daac.asf.alaska.edu/
