AB: We have established several Web Map Services (WMS) that provide visualizations of numerical weather model data and satellite observations in support of NASA's Modeling, Analysis and Prediction Program 2005 Intensive Analysis (MAP05) Hurricane Project. The primary data component offered is the voluminous output (30GB/day) from the fourth-generation Goddard Earth Observing System (GEOS4) incorporating the finite-volume General Circulation Model (fvGCM). In addition, cloud imagery from the NASA MODIS and NOAA GOES sensors, and other ancillary datasets, are provided. We will discuss and demonstrate these servers using a simple web-based client. WMS is a web service interoperability specification developed by the Open Geospatial Consortium (OGC) and also approved for release as an International Standard (ISO 19128). WMS allows the user to request customized images of geospatial information, selecting exactly the dataset(s), times, geographic area and output size desired. A WMS client can combine output from multiple WMS servers, thus producing a unified view of information stored in a distributed network. Adoption of web services for access to hurricane data can be more efficient than older methods of data access. Specifically, instead of downloading huge datasets to a local workstation for analysis, the data can be stored on a remote server that generates visualizations of user-selected subsets of the data. In addition, a "clip-and-ship" capability can allow the user to visually inspect the data via WMS and then request numeric data values for only the subset of interest.
