Grid Viewer

Brief Instructions:

Click 'Select Data'. The data selection window will appear.
In the data selection window choose a model, run time (analysis time) and forecast projection. This will specify a particular data file. You may then Query Fields or Load Data.
If you Query Fields, a new window will appear in 20-30 seconds, listing all the grib variables and levels available in the grib file. These are helpful when you Load Data.
If you Load Data, you may specify either the rec # from the Query Fields information, or the field name and level. Both are case-insensitive, but you must specify the level exactly as it appears in the Load Data window. For instance, you might chose field: "hgt" (without quotes), and level: "975 mb" (without quotes). Or, as another example: field: "cape", level: "255-0 mb above gnd". Hybrid levels are an exception: for those you need enter only the number of the hybrid level you want.
Once the field has loaded, you may move the cursor over the field to see field values.
Use the Change displayed field button to toggle among loaded fields, or delete loaded fields.
Drag (move the mouse while holding down button 1) to choose an area in which to zoom. (The zoom will occur as soon as the mouse button is released.) Undo zooming by clicking the un-zoom or Default button.
Drag the balls on the slider bars to hide all data except those in the range(s) you have selected. Click on a bar to reset the range to its original value.

In order to store more fields withough running out of memory, you may wish to
follow these steps to increase the amount of memory available to the applet.
