PAVICS is a Spatial Data Infrastructure (SDI) for climate data. It is composed of modular components that together provide access to data and a library of climate services. It is meant to facilitate climate data analysis for both researchers and climate service providers. PAVICS is not intended to be installed on individual computers, but rather on servers located close to data archives.
There are multiple building blocks composing the PAVICS SDI:
Web Processing Services (WPS) supporting data processing in the climate science community. It includes multiple sub-components:
- A library of climate indicators.
- Climate services including indices computation, spatial analogs, weather analogs, species distribution model, subsetting and averaging, climate fact sheets, etc.
- Access to ESGF data nodes and THREDDS catalogs, workflow engine.
- Climate Data Operators (CDO) and compliance-checker for netCDF files.
- A WPS server for hydrological modeling, calibration, regionalization of ungauged basins and time series analysis.
- A notebook interface to demonstrate how WPS services can be used from a programming environment.
- The user interface (UI) handling user accounts, workspace, workflows and data visualization. Development of the UI has paused as it consumed a lot of resources, consider it as a prototype.
- Storing and serving information about available climate data.
- Authentication and authorization services.
- netCDF data server.
- Geospatial data server.
These components work together to offer users a seamless access to data and a suite of services that can convert raw climate data into useful information, graphics and tables.
PAVICS is led by Ouranos, a regional climatology research consortium, and CRIM, an informatics and software research institute, (both located in Montreal, Quebec, Canada) to provide climate scientists with a set of tools to acquire and analyze climate data. The project was funded by the CANARIE research software program.
