D2D Model
Plan View Displays
The Volume menu has numerous ways of loading and displaying model grid data. Grid data is a unique data type in AWIPS because it supports displaying data as both graphics (e.g. contours) and images (color-filled layers). While the model data under the Volume menu is more for forecast applications than warning applications and are outside the scope of this RAC-oriented training, we will review some of the model grid data basics that support warning decision making.
The Volume menu contains many different groups of model parameter displays called Families that are tailored to each model. Under the Families section there are single panel family layouts and 4 panel family layouts with linked panel displays. Model families are typically a blend of graphic products (i.e. contours) and image products (i.e. color-filled displays) stacked on top of each other with product legends for each parameter. Many of the parameters are toggled off by default which makes the product legends darker. You you can toggle individual products on using a left mouse click on the product legend or by using the 1-9 numbers (and Shift + 1-9) on the keypad. Any model grid product loaded can be converted to a contour graphic or a color-filled image by right clicking on the product legend and selecting the appropriate submenu.
Most of the families in the Volume menu are standard forecast parameters like 500mb height and vorticity and mean sea-level pressure, but the families at the bottom of the menu support particular forecast problems (e.g. Convect, Surface, Winter)
