Is there cleaner alternative of the original JAXA ALOS AW3D30 digital surface model (DSM) data?

The team from JAXA made a great job on DSM derived from ALOS-2. However, I find issues on data, e.g.:

• satellite stripes footprints, elevation drops by 1 to 5 metres
  
• rare, but obvious noise in data
  

Is there any version with cleaned/postprocessed global dataset, which deals with imperfections of AW3D30 data? (e.g. SRTM data were upgraded multiple times by various communities).
