AbstractThe survey data of Wide-field Infrared Survey Explorer(WISE)provide an opportunity for the identification of galaxy clusters.We present an efficient method for detecting galaxy clusters by combining the WISE data with SuperCOSMOS and 2MASS data.After performing star-galaxy separation,we calculate the number of companion galaxies around the galaxies with photometric redshifts previously estimated by the SuperCOSMOS,2MASS and WISE data.A scaled richness R_(scal) ≥30 is set as a criterion to identify clusters.From a sky area of 275 deg~2 of the Sloan Digital Sky Survey Stripe 82 region,we identify 302 clusters in the redshift range of 0.1
