Abstract. We present Spitzer 70 and 160 micron observations of the COSMOS
Spitzer survey (S-COSMOS). The data processing techniques are discussed
for the publicly released products consisting of images and source
catalogs. We present accurate 70 and 160 micron source counts of the
COSMOS field and find reasonable agreement with measurements in other
fields and with model predictions. The previously reported counts for
GOODS-North and the extragalactic First Look Survey are updated with the
latest calibration, and counts are measured based on the large area SWIRE
survey to constrain the bright source counts. We measure an extragalactic
confusion noise level of {sigma}_ c_ = 9.4 +/- 3.3 mJy (q = 5) for the
MIPS 160 micron band based on the deep S-COSMOS data and report an updated
confusion noise level of {sigma}_ c_ = 0.35 +/- 0.15 mJy (q = 5) for the
MIPS 70 micron band.
