Hello... I've had a great deal of trouble downloading the 1998 to 2014 NSRDB via globus. After nine days of trying I've racked up 400 GB of bandwidth with no file to show for it. The download is locking up and/or restarting after completion and overwriting the already downloaded file.
Consider breaking up the file into smaller chunks. Perhaps by state or region - southwest, midwest, PNW etc.
Another option would be to produce csv files for a year's worth of data using the coordinates of the traditional weather stations in the 1990 to 2010 dataset.
