[gradsusr] Time Series Plot

[Jeff Duda]

If your data were processed on pressure levels (as it appears to have
been), you're most likely seeing missing data due to being below the ground
surface at those pressure levels. Depending on which post-processor you
used, you will need to make sure to set it to interpolate pressure levels
below ground level. I recommend using the Unified Post Processor software,
as I think it implies that automatically (plus, you can just use the
terrain height field to mask out values below ground anyway).
