Hello, I'm afraid I can't provide too much information about the data hosted by NOAA; while we maintain and publish several of the software packages they are using to provide data, we are not actively involved with managing their data portals. I've done a little bit of investigation and have found the following in regards to how data can be accessed: * https://www.nodc.noaa.gov/access/services.html This page appears to offer lots of data available from a number of services (http, ftp, THREDDS, OPeNDAP, etc). I'm able to click through and navigate the data sources without needing to register, but I'm unable to actually find anything I would download, so I can't confirm that registration is not required. From the look of it, I suspect it may not be. Finding data can be very difficult, particularly for a non-domain expert such as myself. I assume you are a domain scientist for whom the descriptions/metadata are meaningful, but cannot find the data you are looking for. I was able to find some NOAA resources related to their metadata organization, available here: * https://www.ncddc.noaa.gov/metadata-standards/ I confess that, as a computer scientist, much of the domain-specific information is not intuitive to me, but perhaps it is more meaningful to you? You don't ask about visualizing or working with the .nc files once you have them 'in hand', so to speak; I assume you have tools at your disposal for working with netCDF files. If not, please let me know and I'll provide as much help as I'm able to. In the meantime, if the links above are not helpful, you might try contacting NOAA directly; I'm sure they can provide more help, as this is a resource they maintain. I found the following contact information which may prove useful for you: * https://www.nodc.noaa.gov/about/contact.html I hope this helps, have a great day, -Ward > Hello, > > I am trying to access data on the NOAA site (https://www.nodc.noaa.gov/). > However, I am not able to download or read .nc files.
