Uses perl lists for representing netCDF variables. A cross section of the data volume can be viewed in a 2D window as a 2D contour plot, a vector plot, a raster image or a combination of these options superimposed.
Map outlines can be used as a background for 2D cross section plots of geographic data. All data is projected according to the coordinates specified by the user for the cross section window. The user interface provides direct manipulation tools for specifying the eye position, center of view, light sources, and color ramps. Subsetting of data can be done easily by selecting the data by index or geographic coordinate. On-line contextual help provides easy access to more detail about the software.

The bindings also use the udunits library to do unit conversions. The package from Konrad Hinsen has been integrated into his ScientificPython package.
NetCDF Python module. NetCDF and pynetcdf. The R Project for Statistical Computing has developed R , a language and environment for statistical computing and graphics.
It provides a wide variety of statistical and graphical techniques, including linear and nonlinear modelling, statistical tests, time series analysis, classification, and clustering. Robert Hijmans with additional contributors has created the R raster package for geographic data analysis and modeling.
The raster package can be used for reading, writing, manipulating, analyzing and modeling gridded spatial data. The package is especially useful for large datasets that don't fit into memory, because data is processed in chunks. See Introduction to the 'raster' package for more information. QGIS supports a desktop, browser, server, and client for viewing, editing, analysis, serving, and accessing data.
This interface is intended to cover all the functionality of the C library for netCDF. Also available are combination functions such as iterators which offer abstract ways to scan files and variables.

If you need help getting started, a remote tutorial is available once you've downloaded the package. It currently requires JDK 1. Dataset is an in-memory representation of a netCDF file.
Zebra's primary use is for the superpositioning of observational data sets such as those collected by satellite, radar, mesonet and aircraft and analysis products such as model results, dual-Doppler synthesis or algorithm output. Data may be overlaid on a variety of display types, including constant altitude planes, vertical cross-sections, X-Y graphs, Skew-T plots and time-height profiles. The fields for display, color tables, contour intervals and various other display options are defined using an icon based user-interface.
This highly flexible system allows scientific investigators to interactively superimpose and highlight diverse data sets; thus aiding data interpretation.
Data handling capabilities permit external analysis programs to be easily linked with display and data storage processes. The data store accepts incoming data, stores it on disk, and makes it available to processes which need it.
An application library is available for data handling. The library functions allow data storage, retrieval and queries using a single applications interface, regardless of the data's source and organization. NetCDF data that conforms to Zebra conventions is supported by this interface.

It includes a toolset for visualizing the data stored in the space-time netCDF cube in both 2D and 3D. Emerging Hot Spot Analysis then takes the cube as input and identifies statistically significant hot and cold spot trends over time.
You might use the Emerging Hot Spot Analysis tool to analyze crime or disease outbreak data in order to locate new, intensifying, persistent, or sporadic hot spot patterns at different time-step intervals.
The Local Outlier Analysis tool takes the cube as input to identify statistically significant clusters of high or low values as well as outliers that have values that are statistically different than their neighbors in space and time. The Utilities toolset enables you to visualize the data and analysis results stored in the space-time cube in two and three dimensions.
These visualization tools can be used to understand the structure of the cube, how the cube aggregation process works, and to visualize the analytical results added to the cube by other Space Time Pattern Mining tools. See Visualizing the Space Time Cube for strategies to allow you to look at cube contents. Applied Science Associates, Inc.
