All-sky maps of the thermal emission from the zodiacal cloud, according to the Kelsall model and two meteoroid engineering models (Divine 1993; Dikarev et al. 2005a) populated by the carbonaceous particles, as seen from Earth at the September equinox, for selected wavebands of the COBE, Planck, and WMAP observatories. The reference frame is ecliptic, the Mollweide projection is used, each map’s center points to the antisolar direction (i.e., the vernal equinox), a 30°-wide band around the Sun is masked. The grayscale of the upper row of maps is in MJy sterad^-1, the other rows are in μK of a temperature in excess of the CMB. Each map has its own brightness scale.
