Access to data set

On the info pack, it says

The full list of Data Sets are available on Devpost
These will include:
• MERRA: Modern-era retrospective analysis for research and applications
• Nasa Surface meteorology and Solar Energy
• AURIN: Australia’s urban intelligence network geo-datasets
• BoM one Minute Solar Data
• Air-conditioner location running hours data
• Datasets from 2015 GovHack

I opened all the links and they all need account
How do we access the data?
