Hi Philip:
Both 'ncdf4' and 'Rnetcdf' should be able to download data using OPeNDAP. That the package is using OPeNDAP is transparent to the user, other than the fact that the "file" is an URL. Extracts are just like reading a netCDF file using these packages, so you may have to spend some time learning how to do that. It is possible that 'tidnyNC' can also do OPeNDAP, I am just not certain that. -Roy > On Aug 13, 2020, at 8:59 AM, Philip <herd_...@cox.net> wrote: > > Daniel Bowman wrote a wonderful package to access National Weather Service > data with R. > > Unfortunately I stuck trying to download archived Rapid Update Forecasts > (RAP) going back into 2016.
