International Activities and Collaborations
Status Report: April 2013 - September 2013
Strategic Focus Areas
The Group Name group's work supports the following Unidata funding proposal focus areas:
- Develop and provide open-source tools for effective use
of geoscience data
The majority of tools downloadable from Unidata are available free-of-charge to everyone (the exception being McIDAS-X).
- Provide cyberinfrastructure leadership in data discovery,
access, and use
Activities of the Unidata Program Center are routinely provided to the worldwide atmospheric science community. Strategic partnerships with leading organizations in other countries minimize the impact on UPC staff.
- Build, support, and advocate for the diverse geoscience community
By informing the international atmospheric science community of the products, data and services available in the Unidata Program, an extended community has been enabled.
Non-U.S. users of products available from Unidata reflect, in a number of cases, minority constituencies in the U.S. atmospheric science community.
Unidata's Africa-related international outreach activities have largely focused on its role in the UCAR Africa Initiative (AI) which officially ended on April 15. The UPC is currently involved in transfer of technologies developed during the UCAR Africa Initiative project to the African Centre of Meteorological Application for Development (ACMAD) which is located in Niamey, Niger. The following are some highlights of the UPC's involvement in the UCAR Africa Initiative:
- The IDV was used to generate displays of forecast relative humidity
that is created using TIGGE ensemble data from ECMWF (via the NCAR/CISL
TIGGE repository). The 2013 products and data being made available in
the RAMADDA instance on motherlode.ucar.edu can be found in:
Projects -> Africa Initiative -> Data -> 2013 Prediction Exercise
-> Areal Coverage
-> TIGGE Model Ensembles
- areal distribution of the 50% quantile for RH (which means that each
point in the RH field has a 50% probability of being that value
These products have been stored as animated GIFs, individual frames of the animated GIFs, and week 1 and 2 averages.
- probe timeseries plots of QC25, QC50, and QC75 fields for districts
(a district is a subdivision of a region which is like a U.S. state)
in a select set of countries (Benin, Burkina Faso, Cote D'Ivoire, Nigeria,
Senegal, Tchad, and Togo) that are located in the meningitis belt
(which is roughly the Sahel) in Africa.
Also made available were the RH and quantile regression fields
(in netCDF format) that are created from ECMWF ensembles that are
part of TIGGE.
- areal distribution of the 50% quantile for RH (which means that each point in the RH field has a 50% probability of being that value or less).
- The final stage of AI work in Unidata included automating the generation
of display products upon receipt of a new forecast file produced in RAL (by
- The programmatic use of the IDV
- Use of RAMADDA to serve display products to the African Decision
Information System (ADIS) interface that Arnaud Dumont (NCAR/RAL) created for
- Scraping human-generated documents to get the list of districts for
which probe time series plots should be generated.
- The programmatic use of the IDV
Other activities of note:
- Data from UCAR GOES East/West ingest systems continue to be routinely accessed by international users in North, Central and South America using McIDAS-X, IDV, and McIDAS-V.
- Use of Unidata tools, especially netCDF, the IDV and GEMPAK, continues to grow internationally.
- IDD-Brazil continues to deliver data via the LDM in Africa.
