In the spring of 2010, the Department of Atmospheric and Environmental Sciences (DAES) at the University at Albany, State University of New York received funds from Unidata's annual Community Equipment Awards program to renovate the department's electronic map room. As a result, during the summer of 2010 our department purchased eight Dell Optiplex 780 desktop computers with dual-quad core CPUs (thus eight CPUs are available per unit) and eight GB of RAM. The machines were received too late in the summer to be ready for the fall semester, but were in place for the start of the second semester in January, 2011. Seven of the systems sit in the DAES electronic maproom, while the eighth resides in the Principal Investigator's office, for use as a development machine as well as an emergency hot spare.
Indexed data access exposes the physical schema of datasets and makes violations of the relationship between coordinate and indices commonplace for datasets that change, such as aggregations of rolling archives. Making data requests in coordinate space will be added to the next generation of data access protocols, partly in order to solve this problem.
