WRF Viewer
Yosemite can be used as a tool set to produce forecaster-customized analysis and forecast products from WRF or other external data sets.
For example, Yosemite-generated maps of WRF surface data can be used to forecast small scale coastal eddy and wind phenomena in summer, as well as cold frost pockets in the valleys during the frost season. Features such as these are not as easy to quickly identify using other models or platforms for display.
A Yosemite based system can act as a server to upload these customized products to a website for quick remote access.
Handling External Datasets
Yosemite processes several types of model and gridded data that you may provide as external files, just as if they had been received on Noaaport.
A huge advantage to using Yosemite as the display system for your custom model data is that it doesn't just make a pretty picture - it automatically publishes complex content to your website, and is also used to generate decoded reports that go into your other downstream processes.
The report outputs can be simple comma-delimited text files containing each value at each gridpoint at each forecast hour, or they can be more complex, such as an XML-formatted soundings from your model data at each gridpoint for each forecast hour.
WRF & MM5 Models
With the latest in powerful personal computers, it's now practical to run your own computer model using the WRF or MM5 software from NCAR, and more small shops are doing exactly that to obtain high-resolution forecasts for their own domains.
Marta Systems' Yosemite™ software is fully compatible with the output from WRF and MM5, and can be used to display and publish graphic products or generate formatted reports from your models.
Typically, your model will generate standard Grib Edition 1 or Edition 2 files, and drop them into a folder that Yosemite is aware of. When Yosemite finds your files, it immediately processes the model data, so it can be used in your automatically published output products.

XML-Formatted Lat-Lon Gridded Data
If you have external processes that generate data values on Lat-Lon positions, even if they are not spaced on a regular grid, they can be processed by Yosemite in a manner similar to GRIB model data, where the data set can be contoured and rasterized.
By generating a file with a simple XML-formatted header containing time, parameter, units of measure and naming information, and then including your comma-delimited gridded data points, Yosemite will ingest and process this data so that it can be used just like model data in a graphic.
