## [32.03] Observations and Modelling of the Zodiacal Light

T. Kelsall (NASA/GSFC)

The DIRBE instrument on the COBE satellite performed a full-sky survey in ten bands covering the spectral range from 1.25 to 240 $\mu$m, and made measurements of the polarization from 1.25 to 3.5 $\mu$m. These observations provide a wealth of data on the radiations from the interplanetary dust cloud (IPD). The presentation covers the observations, the model-independent findings, and the results from the extensive efforts of the DIRBE team to model the IPD. Emphasis is placed on describing the importance of correctly accounting for the IPD contribution to the observed-sky signal for the purpose of detecting the cosmic infrared background.
