WebMar 16, 2024 · ALOHA Software. ALOHA is an acronym for Areal Locations of Hazardous Atmospheres. ALOHA is the hazard modeling software program for the CAMEO software suite, which is used widely to plan for … WebALOHA includes equations to account for release rates that change over time and for dispersion in the along-wind direction that is caused by processes such as wind shear. For urban areas, ALOHA uses a different set of Briggs dispersion coefficients (numbers which describe the vertical and crosswind extent of a dispersing gas cloud).
