Abstract: The SOLAR2000 empirical solar irradiance model produces nowcast and forecast solar irradiances for all time scales from the current 24-hour epoch to the next solar cycle. A description of the nowcast and forecast irradiances is provided, including the E10.7 proxy that is created as a special feature of SOLAR2000. E10.7 is the integrated EUV energy across the 1-105 nm spectrum. Advanced algorithms for the forecast of solar irradiances are being designed by a research team and the outline of those algorithms will be discussed. Updates to the SOLAR2000 model itself over the next year, featuring the inclusion of the NOAA 16 Mg II data, the SNOE XUV data, the SOHO/SUMER spectral atlas, and the TIMED/SEE data will be described. Additional updates to SOLAR2000 will be presented and will consist of an FUV variability model, new spectral wavelength formats for use in numerical atmospheric models, and callable IDL code for using SOLAR2000 as a subroutine.
