The observations cover a 1.5°x1.5° area and allow us to investigate the overall molecular environment of the remnant. Some northern and northeastern partial shell structure of CO gas is around the remnant. One of the partial shells, about 5' extending beyond the northeastern border of the remnant's bright radio shell, seems to just confine the faint radio halo. On the other hand, some faint CO clumps can be discerned along the eastern boundary of the faint remnant's radio halo. Connecting the eastern CO clumps, the northeastern partial shell structures, and the northern CO partial shell, we can see that a half molecular ring structure appears to surround the remnant. The LSR velocity of the half-ring structure is in the range of -5 km/s to -2 km/s, which is consistent with that of the -4 km/s molecular clouds. We suggest that the half-ring structure of the CO emission at VLSR~-4 km/s is associated with the SNR. The structures are possibly swept up by the stellar winds of SNR IC 443's massive progenitor. Based on the Wide-field Infrared Survey Explorer and the Two Micron All Sky Survey near-IR database, 62 young stellar object (YSO) candidates are selected within the radio halo of the remnant. These YSO candidates concentrated along the boundary of the remnant's bright radio shell are likely to be triggered by the stellar winds from the massive progenitor of SNR IC 443. Description: The infrared (IR) photometric data used in this work were from the Two Micron All Sky Survey (2MASS; Skrutskie et al. 2006AJ....131.1163S, Cat. VII/233) and the survey of the Wide-field Infrared Survey Explorer (WISE; Wright et al. 2010AJ....140.1868W). The 2MASS survey provides the near-IR photometry in the JHKS bands with 10σ limiting magnitudes of ∼15.8, 15.1, and 14.3 mag, respectively. The WISE survey covered the IC 443 region at the wavelengths of 3.4, 4.6, 12, and 22 um with spatial resolutions of 6.1", 6.4", 6.5", and 12.0", respectively. The 10σ limiting magnitudes are estimated to be ∼15.7, 14.7, 10.4, and 7.1 mag in the WISE [3.4], [4.6], [12], and [22] bands, respectively.
