ALOHA (Area Locations of Hazardous Atmospheres) is a software program designed to model chemical releases for emergency responders and planners. With help from ALOHA, users can calculate how quickly chemicals are escaping from various locations. The program also allows users to model hazardous scenarios.

With the help of ALOHA, you can calculate how quickly chemicals are escaping from tanks, puddles (on both land and water), and gas pipelines and predict how that release rate changes over time.

The program generates a variety of scenario-specific outputs, including threat zone plots, threats at specific locations, and source strength graphs. You can then display threat zones on MARPLOT maps (and on ArcView and ArcMap with the Arc Tool extensions).

Google Earth is a virtual globe, geographical program created by Google. The program uses digital elevation model (DEM) data collected by a NASA space shuttle to create the 3D map.  With Google Earth, viewers can view satellite imagery of large portions of the globe.  Users can also explore ocean topography, and switch to street view which enables someone to explore roads as if they were in a car.  New features of Google Earth allow a user to explore regions of the moon, Mars, and constellations in the sky.  New features are being added and existing features enhanced frequently.

Google Earth is available for free download here.  A Professional version with enhanced geo-coding, map-making, and GIS features is available as well.

GEMPAK, the GEneral Meteorology PAcKage, is an analysis, display, and product generation package for meteorological data. It is developed by NCEP (the National Centers for Environmental Prediction) for use by the National Centers (Storm Prediction Center (SPC), Tropical Prediction Center (TPC), Aviation Weather Center (AWC), Hydrologic Prediction Center (HPC), Marine Prediction Center (MPC), Environmental Modeling Center (EMC), etc.) in producing operational forecast and analysis products such as those distributed as Redbook Graphics and others displayed on the NWS web pages and utilized internally within the centers. Graphical User Interfaces provide convenient access to interactive data manipulation. A comprehensive set of decoders enables integration of real-time and archive data, products, and bulletins. The GEMPAK distribution consists of a suite of application programs, Graphical User Interfaces (GUIs), meteorologic computation libraries, graphic display interfaces, and device drivers for the decoding, analysis, display and diagnosis of geo-referenced and meteorological data.
