We present multiband IR observations of the zodiacal light obtained from the MSX SPIRIT III sensor. Each observation sampled the zodiacal emission over a narrow strip of sky covering -15 < ecliptic latitude < 15 degrees. All observations were taken at solar elongation between 90 and 180 degrees . The central wavelengths of the bands are about 8.3, 12.3, 14.7, and 21.6 micron. The temperatures of the zodiacal dust were computed from the multiband data. We show both the flux distribution of the zodiacal emission and the derived temperatures. A comparison between the results obtained using the new observations and that from COBE was made. The outcome of the comparison is also discussed.
