NASA's Global Hydrology Resource Center (GHRC) Distributed Active Archive Center (DAAC) published the GPM Ground Validation Airborne Snow Observatory (ASO) OLYMPEX dataset which contains snow depth, bare earth surface, land surface classification and a Red, Green, Blue (RGB) composite image. The data are provided at 3 m spatial resolution and are available as part of the GPM Ground Validation Olympic Mountains Experiment (OLYMPEX) field campaign held in the Pacific Northwest during late 2015 to early 2016. The ASO dataset was collected by a Riegl Q1560 scanning LiDAR and an ITRES CASI-1500 imaging spectrometer, both part of the NASA Airborne Snow Observatory (ASO). The ASO flew during two separate periods, February 8-9, 2016 and March 29-30, 2016, to represent mid-winter and max-snow amounts in the Olympic Mountains. The dataset also contains “no snow” measurements made in September 2014. These bare earth measurements are used to derive snow depth from the Feb/Mar 2016 observations. The data are provided in GeoTIFF format.

NASA's Socioeconomic Data and Applications Center (SEDAC) released the Historical Urban Population: 3700 BC - AD 2000 data set on 4 May. The data set, developed by former UWG member K. Seto of Yale University, provides population estimates for settlements at different points in time across six millennia based on diverse historical data sources.
