Tools

The Nevada Climate Change Project has produced several software tools and systems. Software tools are created as a part of the research and development efforts of the project itself, and are released to the public to contribute to the pool of tools available to developers and researchers, improving their ability to more easily utilize climate change data.

In terms of software systems, the Nevada Climate Change Project will create, as one of its primary goals, a framework for interconnecting climate models and data. This system – entitled “The Demeter Framework” – is designed to specifically address the need for researchers and climate modelers to create data processing pipelines, spanning multiple data sources, models, and processing steps.

The Demeter Framework

The Demeter Framework is a web-based framework that allows the user to create custom scenarios for model coupling. By utilizing powerful web services, the user can access a library of models, data sources, visualizations, and other activities that have been written by scientists and programmers for use with this system. The system is user-driven, allowing developers and modelers from all over the world to register their models and data sources as "activities" for use, and couple those models with the existing activities already in the system. Currently, these activities can take the form of web services or .NET-compatible libraries.

The main author of Demeter and its Persephone GUI interface is Eric Fritzinger, a UNR Computer Science and Engineering R&D faculty and software professional. He can be contacted at ericf@cse.unr.edu.

The SUNPRISM Framework

The SUNPRISM framework defines an approach and provides tools aimed at supporting scientific investigation via new capabilities for combining data transformations, model simulations, and output visualizations in application scenarios developed for climate change research.

The main author of SUNPRISM is Sohei Okamoto, who developed it part of his PhD in Computer Science and Engineering at UNR. Sohei can be contacted at sohei.okamoto@gmail.com.

The Web Enabled Date & Modeling Toolkit

Web Enabled Date & Modeling Toolkit (WEDMIT) is a combination of a web enabled application with a cross platform desktop application. WEDMIT is primarily aimed to address the data and model interoperability challenges. Researchers in environmental sciences work with datasets that have a large variety of data structures and file formats. Consequently, for data and model interoperability, it is essential to have the right tools for converting from a given data structure to another, and from a specific file format to another. WEDMIT is an original web-enabled approach for generating data processors capable of handling a multitude of data operations, including numerous data conversion and processing activities.

The main author of the WEDMIT is Jigar Patel, who developed it as part of his Ph.D. in Computer Science and Engineering at UNR. Jigar can be contacted at jspatel@cse.unr.edu.

The VISTED Tool

VISTED is a visualization toolset for environmental data. The main goal of the VISTED is to help the climate researchers in visualizing the datasets and also giving them the flexibility in choosing the data of their interest. VISTED tool suite includes new capabilities such as data extraction and interoperability of various data formats. The tool will allow users to extract, view, download, and visualize data. It will input and download data in netCDF, ASCII, HDF5, and CSV formats. The time series charts, and maps will help in visualizing the data. And finally, to support several browsers, operating systems, and hardware devices HTML5 is adopted.

The main author of the VISTED is Likhitha Ravi, who developed it as part of her research assistantship in the Computer Science and Engineering department at UNR. Likhitha can be contacted at likhitha.ravi@gmail.com.

The ATMOS Toolkit

The ATMOS toolkit provides Access to Tabular and Map-based Online Services. It is an ASP.NET web application that aggregates climate change data from various web services and presents that data in a uniform way to researchers. The toolkit uses a set of plugins to provide access to various data sources, and can be extended by writing new plugins to access additional data sources. The fact that multiple disparate services are being accessed through multiple plugins is transparent to the end user, who accesses data through the web front-end.

The main author of ATMOS is Andrew Dittrich, who developed it as part of his master's thesis in Computer Science at the University of Nevada, Reno. Andrew can be contacted at andy.dittrich@gmail.com
