Greetings Frank and Kathryn, First, let's check out the Point Data plot. If you create a Point Data plot, you will indeed see the location marker and station ID. In order to view the data, you'll need to select a more detailed station layout model. Here's how you can do that: * Load the gempak surface file * Create your plot * Go to the Dashboard window and click on the Displays tab * Select the point data source in the left under "View 1" (most likely called Netcdf Point Data - ...). * Look in the middle of the Dashboard (the middle of the Dashboard will look pretty much like this: http://www.unidata.ucar.edu/software/idv/docs/userguide/controls/StationModelControl.html) and select the Layout tab and look for the "Layout Model" dropdown box * The dropdown box is probably set to Location - change that to Observations -> METAR You can also edit the layout to fit your needs; check out http://www.unidata.ucar.edu/software/idv/docs/userguide/tools/StationModelEditor.html for more info. As for plotting the Gridded Fields created from the gempak file, I am unable to recreate the issue you are having. Which version of the IDV are you using? Cheers!
