Hi HP,
I figured it out. This isn't a gridded netCDF file (which McV tries to load the data as), but a point netCDF file. Through the General>Files/Directories chooser, select "netCDF/GEMPAK Point Data files" from the Data Type dropdown, select your file, and click Add Source. From working with this data in the past, you'll likely already be familiar with the following steps to create a display, but I'll add it for completeness:
Each data point is its own timestep. Because of this, attempting to create a display with the data source in its initial form will lead to 1985 timesteps. You can bin the points together into one timestep by double-clicking on the name of the data source on the left side of the Field Selector tab of the Data Explorer to open the
Properties window for the data source. From here, I adjusted the Time Binning settings at the bottom of the Properties tab to:
- Bin Size: 1 day
- Round To: 1 hour
You could modify these values if you are looking to display a loop and not the entire swath at once.
From here, you can select your gridded field and display type. You will likely want to experiment with different options in the
Grid Parameters tab to get McIDAS-V to plot a swath roughly fitting to the data points. As a quick test with the rad_water_vapor_01_ku variable, I set the following:
Spacing: Degrees
Grid Size: 0.05 x 0.05
Passes: 2
Search Radius: 1
Gain: 1
These values, with the Image Display display type, produce a narrow strip of data in the display that follows along the path of the data. To verify the display was correct, I overlaid the Image Display with a Point Data Plot of the Point Data field which doesn't use any gridded interpolation to create the display.
Please let me know if you have any other questions about this.
Thanks again,
Bob
