Abstract : The NRL Environmental Data Browsing System (NEBS) is a graphical user's interface (GUl) designed to visualize 40 (x,y,z,t) gridded field data from numerical models to help evaluate and diagnose model behavior. It allows the user to quickly slice and animate data displays in x,y,z, or t and easily reveals anomalies and erroneous trends. Setting dimensions at any identified problem's conditions provides a quantitative listing of individual variables. Variables and dimensions can be easily set using mouse button clicks on the displayed GUl buttons. The NEBS uses the Grid Analysis and Display System (GrADS) developed by the Center for-Ocean-Land-Atmosphere Interactions (COLA) at the University of Maryland. NEBS can be used to browse almost any data in the GrADS IEEE 4 real binary format and other data formats supported by GrADS (e.g., gridded binary format (GRIB)). NEBS and GrADS are supported on a variety of Unix platforms including Digital, IBM, Hewlett-Packard, NeXT, Silicon Graphics, Sun, and Concurrent. Graphics are displayed quickly and can be animated on a host platform at about one frame per second or about one frame per two seconds over a high speed LAN.
