Abstract : A software package has been developed for the Penn State/National Center for Atmospheric Research Mesoscale Model to allow interactive bogusing. This package was developed to allow the production of more realistic objective analyses. Previously, the process of inserting synthetic data in order to improve the objective analysis was done manually, which was inefficient and time-consuming. The new procedure described in this thesis uses newly developed bogusing software to make the process more efficient. The software has three parts: a data creation (bogusing) component, an objective analysis component, and graphics routines for displaying objective analysis output. To use this software, the user transfers an objective analysis from NCAR, where it is generated on the CRAY computer, to the user's local site. Next, these data are loaded into a supermicrocomputer. Using the graphics software, the user checks the analyses to see if bogus data are needed. If so, the bogusing software is used to efficiently create the synthetic data, and the objective analysis software is to run to analyze the influence of these data. The user reexamines the analyses with the interactive graphics software and can repeat the cycle as needed until the desired initial conditions are created. These newly created bogus data are then sent back to the CRAY for use as numerical model initial conditions.
