NCAR's NSF funding history for the previous three years is presented in Table 4 below. The table represents new funding received during each fiscal year and does not represent actual expenditure activity. NCAR receives NSF funding in two ways: (1) NSF Regular funding through an annual program plan target, and (2) NSF Special funding through a separate allocation and grant process.

The NSF Regular Funds target consists of base and focused program funding, with a separate allocation for the Climate Simulation Laboratory (CSL). A more detailed description of the funding sources is presented in the Program Performance section on pages 10 and 11. NSF Base Program funding represents NCAR's more flexible general budget and has remained essentially flat over the three-year period. Focused program funding consists of U.S. Global Change Research Program and High Performance Computing and Communication support. In FY 1995, $1.7M of the focused program budget was allocated to CSL. Included in the CSL figures is a yearly allocation of $0.67M from the Mathematical and Physical Sciences Directorate.

NSF Special Funds consist of deployment funding for field support costs and research grant funding for special programs, such as the Coupling, Energetics, and Dynamics of Atmospheric Regions program. In FY 1994 and primarily in FY 1995, NCAR received special allocations of $0.16M and $0.75M, respectively, to modify and upgrade aircraft for research operations.

Table 5 presents a three-year expenditure history for all UCAR programs, including NCAR, UCAR Office of Programs, and other related activities.

NCAR program expenditures averaged approximately 79% of total UCAR spending over the three-year period. Annual expenditures are not equal to funding on a fiscal year basis because the period of performance for much of the funding spans more than one fiscal year.
