Science increasingly requires strong
international partnerships that share knowledge, information, and
other resources. This is particularly true in the geosciences, where
the highly coupled nature of the Earth system and the need to understand
global environmental processes and their regional linkages have heightened
the importance of collaborations across national and continental
boundaries.
Below are two examples in which partnerships among UCAR, NCAR, and
the university community, working with NOAA and NSF, are bringing
South and North American scientists together through the sharing
of weather observations and satellite imagery. Access to these data
has had profound and transformative impacts on higher education in
several South American countries, as well as benefiting students
and researchers throughout the hemisphere.
Real-time weather data through MeteoForum and IDD-Brazil
There are compelling benefits to a global cyberinfrastructure and
networked communities, helping institutions and people to exchange
knowledge, ideas, and resources. Under the sponsorship of NSF, UCAR’s
Unidata Program has developed a growing portfolio of international
outreach activities, conducted in close collaboration with academic,
research, and operational institutions on several continents, to
advance Earth system science education and research. The portfolio
includes data, tools, support, and training, as well as outreach
activities that bring various stakeholders together to address important
issues, with the goal of building a community with a shared vision.
“Now
one only needs inexpensive personal computers and
access to the Internet (with the help and vision of groups like
Unidata) to study phenomena that affect society.”

Castro, University of Costa Rica |
MeteoForum began as a pilot project in 2001 involving two UOP programs:
Unidata and COMET. The latter is itself a partnership sponsored by
NOAA, the U.S. Navy and Air Force, Environment Canada, and Australia’s
Bureau of Meteorology.

Supported by private UCAR funds and COMET and Unidata program funds,
MeteoForum began as a collaboration among four of the World Meteorological
Organization’s Regional Meteorological Training Centers (RMTCs)
and a handful of universities. Together, the four RMTCs span North,
Central, and South America, and the Caribbean. MeteoForum was designed
to help RMTCs improve their service in the areas of hydrometeorology,
agriculture, and disaster management. By accessing a comprehensive
collection of training materials, software, and real-time and historic
data, the RMTCs would be able to enrich the education they offer
to hydrometeorological professionals.
Unidata facilitated the multi-way sharing of data through a regionally
configured and managed extension of its Internet
Data Distribution (IDD) system. MeteoForum RMTC participants are responsible for acquiring
computer hardware and Internet access, working with Unidata and COMET
to train local personnel, supplementing curricula with real-time
data and interactive multimedia materials, and developing and sharing
new curriculum elements. RMTC representatives also translated some
COMET modules into Spanish (see
related article).
One important outgrowth of MeteoForum has been the emergence of a
data distribution system for South America, the IDD-Brazil. This
collaboration involves Unidata and several Brazilian institutions,
including
- the Federal University of Rio de Janeiro,
- the University of São Paulo,
- the Federal University of Pará, and
- the Center for Weather and Climate Studies (CPTEC).
The creation of IDD-Brazil was in line with Unidata’s broader
goals of facilitating real-time data access at no cost for educators
and researchers and supporting faculty in making use of these data,
while building a community where data, tools, and best practices
in education and research can be shared. The Brazilian and North
American IDDs are now components of a hemisphere-wide network that
has catalyzed sharing of international, national, and locally held
environmental datasets (see figure). Previously unavailable observational
data and high-resolution model output for Brazil can now be accessed
in near–real time by participants throughout the Americas.
The IDD continues to expand: it has recently been extended into Antarctica,
and efforts are under way to extend it to the Caribbean and Africa.
The IDD-Brazil has helped initiate teaching innovations in multiple
geoscience disciplines at the universities of Costa Rica, Buenos
Aires, Rio de Janeiro, São Paulo, and Chile, among others.
As many professors of meteorology know, there is no substitute for
current weather data to stimulate students’ interest. Integration
of real-time world data has provided opportunities for student-centered
and inquiry-based learning, infusing the excitement of discovery
into geoscience courses at these institutions.
Bringing GOES-10 satellite data for South America to the community
Another recent partnership is making satellite data for South America
freely available to the university and broader community. In
July 1998, NOAA’s tenth Geostationary Operational Environmental
Satellite (GOES-10)—launched the year before—was moved
into position to serve as GOES-West, gathering imagery from above
western North America and the eastern Pacific Ocean. GOES-10 recently
passed the end of its expected lifespan. However, NOAA’s National
Environmental Satellite, Data, and Information Service (NESDIS) recognized
that GOES-10 could perform a valuable function if it were devoted
to serving South America during its remaining usable life. South
American coverage by GOES-East has always been poor, and it is essentially
non-existent during periods of significant weather in the Northern
Hemisphere. There is a long history of satellites being repurposed
at the end of their expected lifetimes; this was true of GOES-7 in
the United States, and Meteosat-5 and now Meteosat-7 in Europe.
“IDD-Brazil and MeteoForum have provided
a significant
change in our undergraduate and graduate level programs in meteorology.
The free access to real-time information provides a unique experience
for the professors to
use updated information in the classes with case studies based
on regional systems. We are convinced that
our students will have better chances in their professional activities
with the type of training acquired in the use of the facilities
provided by the system.”

and Atmospheric Sciences, University of São Paolo

Through an agreement between the WMO and several Central and South
American countries, NOAA recently agreed to dedicate the GOES-10
spacecraft to routine observations of South America. It will provide
operational weather services with consistent satellite coverage at
high temporal and spatial resolution and complement the more northerly
focus of GOES-East and GOES-West. This will be the first operational,
three-satellite, geostationary constellation in U.S. history, and
GOES-10 will be the first U.S. satellite dedicated to South American
surveillance.
UCAR recognizes the importance of these new data for its community
and is working to provide them in real time through remote server
technologies and in archived form through the NCAR Mass Storage System.
One of the major hurdles in this process is to acquire and archive
the data in the most useful format. Over the last few years, several
groups at UCAR and NCAR have been ingesting and archiving GOES imagery
using SeaSpace’s TeraScan format. While this is extremely useful
for sites with TeraScan analysis capabilities, much of the Unidata
community is more accustomed to working with data in the University
of Wisconsin–Madison’s McIDAS AREA format.

The GOES-10 imagery available
on Unidata’s Web page through a University of
Wisconsin data stream includes hemispheric composites
for visible, infrared, and water vapor imagery. Clicking
on still images activates a 48-hour animation. More

To address this problem, Unidata and several partners recently launched
a proof-of-concept project to ingest GOES-10 data at the NCAR Mesa
Laboratory and make it available in the AREA format through remote
access technologies available through Unidata. This was accomplished
in a very inexpensive fashion, thanks to contributions that include
- a satellite dish excessed by NCAR’s Computational
and Information Systems Laboratory;
- a satellite receiver from an obsolete TeraScan system provided
by NCAR’s Research Applications Laboratory (RAL);
- the SSEC Data Ingestor (SDI) software for GOES ground stations
from UW’s Space Science and Engineering Center;
- an SDI PC interface card contributed by The Weather Underground,
a long-time member of the Unidata community;
- computer room infrastructure provided by RAL; and
- system and network operations support from Unidata, including
expertise with satellite ingest software.
To strengthen the system and provide remote access to real-time
GOES-West data, a new satellite receiver will be purchased and maintained
with the help of expertise from RAL and NCAR’s Earth Observing
Laboratory (EOL). The data will be relayed to the community through
powerful and scalable servers in UCAR and the Unidata community that
make use of Unidata’s Thematic Realtime Environmental Distributed
Data Services. Since NOAA will not be archiving data from the repurposed
GOES-10 spacecraft, RAL and EOL will provide a multi-year running
archive through the NCAR Mass Storage System.
The GOES-10 spacecraft completed its eastward drift from longitude
135°W to 60°W in early December. On the evening of 30 January,
Unidata successfully began ingesting GOES-10 imagery and distributing
it to the UCAR community through the IDD. The data will benefit operational
weather services throughout South America as well as research and
development activities in universities across the Americas, U.S.
government agencies, nonprofit groups, and a variety of international
communities, in addition to NCAR and UOP programs and services.
Together, the access to data from all three operational GOES spacecraft
will greatly enhance existing research and educational endeavors
and allow for the creation of new and unexpected opportunities. Thousands
of students, faculty, and research staff across the Western Hemisphere
will benefit. The GOES-10 imagery will be particularly important
for several field projects whose online catalogs are managed by EOL.
These include the Climate
Prediction Project for the Americas, the
Variability of
the American Monsoon Experiment (VAMOS) Ocean Cloud
Atmosphere Land Study, and the Monsoon
Experiment South America.
