NCAR Celebrates Unidatas 25th Anniversary Eric Barron NCAR Director October 16, 2009 NCARs Mission To understand the behavior of the atmosphere and related physical, biological and social systems To support, enhance and extend the capabilities of the university community and the broader scientific community, nationally and internationally

To foster the transfer of knowledge and technology for the betterment of life on Earth Unidata is a critical component in ensuring that NCAR achieves this mission. NCARs Four Focus Areas Computing capabilities and data delivery Developing/deploying scientific tools and services Advancing Earth-system science Technology transfer for societal benefit

Computing capabilities and data delivery NCARs Computational and Information Systems Laboratory (CISL) and Unidata work together to provide our science community with tools that facilitate data Access and management Visualization Integration and analysis in a robust cyberinfrastructure NCARs Four Focus Areas: Computing Capabilities & Data Delivery

Data Access & Management From satellite and GIS data, to radar imagery, observations, and model output, the international research community can access data through NCARs Community Data Portal (CDP). Run by CISL, the CDP relies on many Unidata software technologies (e.g., netCDF, Local Data Manager, and Thematic Realtime Environmental Distributed Data Services) to meet user access and management requirements.

NCARs Four Focus Areas: Computing Capabilities & Data Delivery Data Access & Management CISL and Unidata staff worked closely to move data collected as part of the THORPEX Interactive Global Grand Ensemble (TIGGE) from the projects 10 global Numerical Weather Prediction centers to the three data archival centers at NCAR, ECMWF, and the Chinese Meteorological

Administration. NCARs Four Focus Areas: Computing Capabilities & Data Delivery TIGGE The Unidata Internet Data Distribution (IDD) system is used to transport the ensemble model data from the providers to the archive centers and between the archive centers. This work began in 2006 and continues today, running 24x7. Unidata's Local Data Manager (LDM) moves data in real time to the three data archival centers at NCAR, ECMWF, and CMA (Beijing). 88 TB/yr, which averages out more than

10 GB/hour, with an 18 GB/hour transfer rate occurring at peak performance. Unidata worked closely with CISL in enhancing the LDM to meet TIGGE data flow needs and helped CISL to establish the TIGGE data portal at NCAR. Data Visualization, Integration & Analysis An IDV image shows the GVs track during T-REX, as well as dropsonde observations, which are color coded by temperature.

Making data as functional as possible is a service NCAR offers our science community. Unidata software (e.g., Integrated Data Viewer, GEneral Meteorology PAcKage) helps researchers view critical geophysical phenomena in multiple dimensions, allows them to mix and match data sets, and aids data exploration that sheds insights on the Earth system. NCARs Four Focus Areas:

Computing Capabilities & Data Delivery Scientific Tools & Services NCARs Earth Observing Laboratory (EOL) and Unidata work closely to ensure field-project data are quickly and easily accessible to users via tools such as the Integrated Data Viewer, Local Data Manager, and Thematic Realtime Environmental Distributed Data Services. EOL and Unidata are united in bringing together a Virtual Operation Center that

offers support during and subsequent to field campaigns. NCARs Four Focus Areas: Developing/Deploying Scientific Tools & Services Advancing Earth System Science NCARs Earth System Laboratory and the wider scientific community look to Unidata for data and tools that advance Earth System Science. Among the assists here: Unidatas real-time weather observations aid WRF forecasts

Used worldwide, netCDF lets researchers manage and use large data sets, such the CCSM AR4 climate runs Visualization tools put perspective on little seen regions of the atmosphere, such as the UTLS. NCARs Four Focus Areas: Advancing Earth System Science Technology Transfer for Societal Benefit One of Unidatas largest data beneficiaries, NCARs Research

Applications Laboratory feeds Unidata information into many of the tools and programs that serve society from its roadway decision-support systems, to aviation efforts that make commercial flying safer, to its many, varied national security applications. NCARs Four Focus Areas: Technology Transfer for Societal Benefit One Conclusion Unidata touches every aspect of NCARs

mission Thank you. NCAR Celebrates 25 Years of Close partnerships and strong ties between Unidata and NCAR Labs, Divisions and Groups Seamless NCAR-Unidata collaboration that occurs at all levels from management to staff the benefits that accrue to NCAR, UCAR and the wider science community that we serve. Thank you
