We present deep, full-sky maps built from Wide-field Infrared Survey Explorer and NEOWISE exposures spanning the 2010 January–2020 December time period. These coadds, which incorporate roughly 8 yr of W1 (3.4 μ m) and W2 (4.6 μ m) imaging, are the deepest ever full-sky maps at wavelengths of 3–5 μ m. Photometry based on these coadds will be a component of DESI Legacy Imaging Surveys DR10.
