ABSTRACT:Extended sources of far-infrared emission superposed on the zodiacal and galactic backgrounds are found at high galactic latitudes and near the
ecliptic plane.
Clouds of interstellar dust at color temperatures as high as 35
K account for much of this complex structure, but the relationship to H I
column density is not simple.
Other features of the extended emission show
the existence of warm structures within the solar system.
Three bands of
dust clouds at temperatures of 150-200 K appear within 10 deg on both sides of
the ecliptic plane.
Their ecliptic latitudes and derived distances
suggest that they are associated with the main asteroid belt.
A third
component of the 100-micron cirrus, poorly correlated with H I, may represent
cold material in the outer solar system or a new component of the
interstellar medium.
