1. CIE TC 2-17 on Solar Simulation Invitation to Participate

2. Purpose Develop and publish tables of spectral energy distributions of solar radiation based on atmospheric, geometrical and time-of-year based parameters that represent applications of interest

3. Objectives Create tables of spectral energy distributions as wavelength bands that are useful for simulation

4. Applications Immediate Interest –UV Exposure testing of materials –Solar loading of vehicles and structures –Photovoltaic testing/monitoring Potential Interest –Solar (thermal) collector testing/monitoring –Window energy systems –Biological ultraviolet studies

5. STATUS Basis: SMARTS2 solar radiation model proposed (Gueymard) Done: Rationale for replacing CIE 85 prepared Done: Comparison of SMARTS2 & CIE 85 Done:Meeting of U.S interests (primarily) on January 25, 2005 in Fort Lauderdale, FL NEXT: Proposed Meeting Europe Fall 2005
