Abstract: The Future Force can benefit from a means for inhomogeneous computer systems to access data objects through the network. A platform that supports this paradigm is JavaSpaces, because they are based on the Java Virtual Machine; the concept ?write once, run anywhere? applies. This report illustrates how a Weather Research and Forecasting (WRF) model output file can be split into objects based on the dimension of the variable and then placed in a JavaSpace, where the data objects are accessible to clients and can be reassembled into their original WRF output file format. A methodology, whereby WRF data is used as the ?background? model for the Local Analysis and Prediction System (LAPS), is discussed; the converse, of utilizing LAPS output to initialize a fine-scale WRF model run is also presented.
