Four large Spitzer programs observed the COSMOS field.
S-COSMOS (PI: D. Sanders) is a deep infrared imaging survey of the COSMOS field with the Spitzer Space Telescope in Cycles 2 and 3 which obtained deep IRAC and MIPS observations over the full 2 square degree field.

COSMOS-IRS (PI: N. Scoville) is a Cycle 5 mid-infrared spectroscopic survey of 55 galaxies at z~0.7 covering the full range of environments at that redshift using the IRS instrument.

SEDS (PI: G. Fazio) is a warm mission exploration science program that covered the central 0.2 square degrees of COSMOS with deep IRAC imaging.

SPLASH (Spitzer Large Area Survey with Hyper-Suprime-Cam; PI: P. Capak) is a ~2900h Spitzer program carrying out deep (~25.5AB mag) IRAC imaging over 3.8 square degrees. This will be used to conduct a comprehensive investigations of the earliest stages of galaxy, AGN and large-scale structure formation on cosmologically important scales, providing deep mid-IR imaging for two major 1.8 deg2 fields (COSMOS and SXDS). These two fields have been the target of, and are scheduled for, unparalleled deep imaging in the optical, sub-mm and radio.
The fields have unique, Hyper-Suprime-Cam (HSC) imaging (to ~27-28 magAB for broad bands across the 0.4-1.0μm wavelength range) along with UV (Galex), X-ray (Chandra/XMM), optical (HST), near-infrared, mid-infrared (Spitzer/Herschel), sub-mm, and radio. The COSMOS field is the primary deep fieldfor the Nu-starmission and both fields have been ranked as high priority deep-field targets for Euclid. These fields also have extensive spectroscopy with Keck (>50nt), Subaru-FMOS (>30nt), VLT (>1000nt), and are the primary targets for the future Subaru Prime Focus Spectrograph (PFS) surveys.
