International Activities and Collaborators
Status Report: October 2011 - March 2012

Strategic Focus Areas
The Group Name group's work supports the following Unidata funding proposal focus areas:
- Broadening participation and expanding community
services
By informing the international atmospheric science community of the products, data and services available in the Unidata Program, an extended community has been enabled. - Developing and deploying useful tools
The majority of tools downloadable from Unidata are available free-of-charge to everyone (the exception being McIDAS-X). - Enhancing user support services
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. - Promoting diversity by expanding opportunities
Non-U.S. users of products available from Unidata reflect, in a number of cases, minority constituencies in the U.S. atmospheric science community.
International Activities Since the Last Status Report
Unidata's Africa-related international outreach activities have largely focused on its role in the UCAR Africa Initiative (AI) which is on a no-cost extension of is Google.org award). The following are some highlights of this activity:
- The IDV is being used to generate displays of forecast relative humidity
that is created using TIGGE ensemble data from ECMWF (via the NCAR/CISL
TIGGE repository). The IDV displays include:
- Areal distribution of the 50% quartile for RH (which means that each
point in the RH field has a 50% probability of being that value
or less).
These products are stored as animated GIFs and individual frames of the animated GIFs and made available through RAMADDA on motherlode:
Projects -> Africa Initiative -> Data -> Weather Forecast
-> Areal Coverage
-> Timeseries
- 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, Cote D'Ivoire, Ethiopia, Niger,
Nigeria, Tchad, and Togo) that are located in the meningitis belt
(which is roughly the Sahel) in Africa.
- Areal distribution of the 50% quartile for RH (which means that each
point in the RH field has a 50% probability of being that value
or less).
- The next stage of work in Unidata includes automating the generation of
the displays upon receipt of a new forecast file produced in RAL (by
Tom Hopson).
- Some of the challenges reside in the programmatic use of the IDV
- Others reside in the use of RAMADDA to serve display products to the
Google Earth/Maps interface that Arnaud Dumont has been creating for
the project (this display is what the AI is proposing as an easy to
use Decision Support System (DSS)).
- Still others reside in scraping human-generated documents to get the
list of districts for which probe time series plots should be generated.
- Some of the challenges reside in the programmatic use of the IDV
- One of the next steps in the effort is the transfer of technologys used
in the various facets of RH forecasts to ACMAD which is located in
Niamey, Niger.
Other activities of note include:
- Data from UCAR GOES East/West/South ingest systems have been routinely accessed by international users in North, Central and South America using McIDAS-X, IDV, and McIDAS-V.
- Use of Unidata tools, especially netCDF and the IDV, continues to grow internationally.
- IDD-Brazil continues to expand in Africa.
