NEOWISE 2018 Data Release Available 19 April

The Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) and IPAC at the California Institute of Technology announce the NEOWISE 2018 Data Release.

The 2018 release includes all data acquired during the fourth year of the NEOWISE Reactivation mission (Mainzer et al. 2014, ApJ, 792, 30), 13 December 2016 to 13 December 2017. These data are combined with the Year 1, 2, and 3 NEOWISE data into a single archive that contains approximately 10.3 million sets of 3.4- and 4.6-micron images and a database of over 76 billion source detections extracted from those images.

NEOWISE Reactivation scanned the sky nearly eight complete times during the first four years of survey operations, with approximately six months between survey passes. With 12 or more independent 3.4- and 4.6-micron exposures made on each point of the sky during each survey epoch, 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.

A quick guide to the NEOWISE data release, data access instructions, and supporting documentation is available on the release introductory website. Access to the NEOWISE data products is available via the online and API services of the NASA/IPAC Infrared Science Archive (IRSA).

NEOWISE is a project of the Jet Propulsion Laboratory/California Institute of Technology. NEOWISE is funded by the NASA's Planetary Science Division.
