Implementing NWNH goals
• Indispensable for addressing many key science questions– Enhanced user support for ALMA, EVLA, VLBA and GBT
• NA ALMA Science Center in CV• Array Science Center in SO• GB Science Ops in GB
• Towards the future– Help realize NWNH highly ranked mid-scale projects
• NANOGrav, PAPER/HERA, FASR– Develop current facilities to maintain best performance– CDL: long term R+D for next generation facilities
• e.g. Digital backend; Signal Processing; design towards manufacturing…
