The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) and the Infrared Processing and Analysis Center (IPAC) announce the NEOWISE 2016 Data Release.

The 2016 Release includes all data acquired during the second year of the NEOWISE Reactivation mission (Mainzer et al. 2014, ApJ, 792, 30), 13 December 2014 to 13 December 2015. These data are combined with the Year 1 data into a single archive that contains ~5.1 million 3.4 and 4.6 micron images and a database of ~38.1 billion source detections extracted from those images.

NEOWISE scanned the sky nearly four complete times during the first two years of survey operations, with approximately six months between survey passes. Twelve or more independent 3.4 and 4.6 micron exposures are made on each point of the sky during each pass. Thus, the NEOWISE archive is a time-domain resource for extracting multiple, independent thermal flux and position measurements of solar system small bodies, as well as background galactic and extragalactic sources.
