Do CMIP5 emergent constraints on the large scale circulation still work in CMIP6?

Is there an “Allocated Project Code” I can use for requesting CMIP5 data to be downloaded at https://www2.cisl.ucar.edu/resources/cmip-analysis-platform/request-cmip-data? I also don’t have a username yet so can’t request CMIP5 data. Any suggestions?

I could put together a script to scrape the monthly fields I think I’ll need for my project and then just run it once I get access on Cheyenne? Will I have access to a few 100 Gb of disk space?
