2.3 CWCB-CSU Interagency Agreement

The WDMP-Colorado Financial Assistance Agreement was awarded to
the CWCB on October 2. 2003. This original assistance agreement had a
completion date of September 30.2004. which did not agree with the proposal.
The CWCB requested a no-cost time extension so that the WDMP assistance
agreement would expire on December 31.2004. In a letter dated December 2.
2003. Reclamation (Randy Jackson. Grants and Cooperative Agreements
Officer) clarified that the period of performance would extend through to
December 31.2004 (this was later extended to September 15. 2005). Because
of the delay in receiving this clarification from Reclamation, the Interagency
Agreement between the CWCB and CSU was not signed until December 9,
2003. However, CSU team members did participate in the Project Kickoff
Meeting at CSU on October 22, 2003 before the Interagency Agreement was
signed. The Statement 01 Work in the CWCB-CSU Interagency Agreement listed
six tasks and 16 related deliverables that were to be completed by the CSU
research team. These tasks, which were included in the Colorado Proposal's
Research Work Plan, are summarized in the following subsections of Section 2.

The Colorado WDMP research proposal to Reclamation and the CWCB-
CSU Interagency Agreement included the purchase of a PC Cluster (1 master +
8 slave nodes, console and net switch) by CSU. These additional PC processors
were needed to double the capacity of CSU's existing PC cluster to allow RAMS
to be run daily for real-time project forecasts. CSU could not order the additional
PC processors until after the CWCB-CSU contract for this project was in place.
The new PC processors were ordered in late December 2003, received around
mid-January 2004, and were installed during the last week of January. During
installation, it was found that two out of the eight slave nodes had incompatible
network cards (server adapters), and those two nodes could not be booted. The
compatible replacement cards for the two nodes were subsequently received and
installed. Full testing of the cluster took place during the second week of
February 2004, and the RAMS real-time forecast runs were switched to the new
cluster in mid-February.

2.4 Task 1 . Set up RAMS over the Denver Water operational cloud seeding
areas and over the locations of the ground-based generators

One of the first tasks completed by the CSU team was to set up RAMS
over the Denver Waler operational winter orographic cloud seeding project area
in the central Colorado Rocky Mountains. When the Colorado WDMP began, the
CSU team found that they could enlarge Grid 3 and still get a 48-hr forecast
completed reasonably fast. The new cluster funded by this project would allow a
larger Grid 3. Their philosophy is bigger is better, because a larger grid provides
forecast guidance for more users over a larger area.
