B -- EVALUATE METSTAT MODEL Sol. Synopsis No. 5-322. Contact Dereck B. Willis, Staff Subcontract Administrator (303) 275-3111, Paulette Fontaine-Weshart, Subcontracts Group Supervisor (303) 275-3127. The National Renewable Energy Laboratory anticipates issuing a Request for Proposal (RFP) in January, 1995 for a project to evaluate the performance of NREL's METSTAT solar radiation model. METSTAT was used to estimate solar radiation for the National Solar Radiation Data Base for the times and locations for which no measured data were available. In order to obtain reliable measures of the model's performance, it is critical that the evaluations be performed with hourly (or shorter time period) 3-element (global horizontal, direct normal, and diffuse horizontal) solar radiation data from locations for which concurrent measurements of the meteorlogical parameters required as input to METSTAT are available. Solar radiation data collected by the NOAA-National Weather Service will not be considered because these data were used in the development of METSTAT. The required meteorological parameters are hourly values for total sky cover, opaque sky cover, dry bulb and wet bulb temperature, barometric pressure, and present weather; and daily values of snow depth. Close proximity of the solar radiation measurement site and the meteorological measrurement site is necessary, NREL anticipates the issuance of one or more subcontracts to organizations with experience in solar radiation modeling who also have access to the required solar radiation and meteorological data. The specific model evaluations to be performed will be negotiated with each organization selected for an award. Firms who have interest with the requisite data and experience in METSTAT model evaluation, who would like to receive a copy of the RFP, are requested to write to Dereck B. Willis at the address given in this synopsis No. 5-332 no later than January 20, 1995. A brief description of the data to be ued for the model evaluations should be given. Telephone requests will not be accepted. (009)
