[ncl-talk] CFSv2 OPeNDAP variable issue

Fri Oct 6 04:56:09 MDT 2017

Hi NCL-talk,

I'm a little perplexed at an issue I've been having. I am using OPeNDAP to read CFSv2 files from https://rda.ucar.edu/thredds/catalog/files/g/ds094.0/2017/catalog.html. When I read in and plot certain variables (2m temp, precip, DSWR) it runs successfully, but other variables (snow depth, soil moisture) the script stalls just as it's about to export the PNGs. If I don't close the script, it will just keep running forever...

This issue has me at a total loss. I've attached the strace command for the failed attempt (reading soil moisture) vs the successful attempt (reading 2m temps) below. Any help or ideas would be much appreciated!

Cheers,
Adam
