Abstract. This work is the first step in a systematic effort to understand and predict the different components of the UV (912 A - 3000 A) radiation field over the entire sky. We have developed a model to predict the ISRF in the UV within a few hundred parsecs of the Sun using the Hipparcos star catalog. We have checked the model through a comparison with the observations of the Belgian/UK UV sky survey telescope (S2/68) on the ESRO TD-1 satellite.

Keywords: Interstellar radiation field (ISRF), diffuse background.
