NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published the Global Precipitation Model (GPM) Ground Validation Duke Soil Moisture Integrated Precipitation and Hydrology Experiment (IPHEx) dataset. This dataset consists of a collection of soil parameters obtained during the IPHEx, which occurred in the Southern Appalachians, including the Piedmont and Coastal Plain regions of North Carolina. The dataset includes measurements during February 27, 2014 through October 17, 2014. The instruments used included Theta Probes, Infrared Thermometers, 200-A Soil Core Samplers, Global Positioning System (GPS), and Soil Thermometers. Data were collected during overflights of the Scanning L-band Active Passive (SLAP) instrument and CS6161 Water Reflectometers were used to collect calibration data in Jordan Lake, NC. Data are available in a variety of formats including shapefiles, Excel, Word, and ASCII files. Browse images of site locations and data are available in JPG format.
GHRC DAAC published the GPM Ground Validation Daily Precipitation Olympic Mountains Experiment (OLYMPEX) dataset on Feb 1st. This dataset consists of a single netCDF-4 data file containing estimates of daily precipitation, both rainfall and snowfall amounts, on a 1/32 degree spatial resolution grid covering the extent of the OLYMPEX field campaign region in the Olympic Mountains of the state of Washington. This data product was created for the GPM Ground Validation OLYMPEX field campaign. These precipitation estimates are based on National Oceanographic and Atmospheric Agency (NOAA) WSR-88D radar and rain gauge data incorporated in NOAA National Severe Storms Laboratory (NSSL) local gauge bias-corrected radar quantitative precipitation estimation (QPE) model (product Q3GC) and the Mountain Mapper QPE model (product Q3MM) products. The Variable Infiltration Capacity (VIC) macroscale hydrologic model was also used to invert snow water equivalent (SWE) measurements from the Airborne Snow Observatory also collected during OLYMPEX. The model precipitation was used for mountainous regions where ground radar is obstructed by the terrain. This precipitation dataset is includes the dates of October 1, 2015 through April 30, 2016.
NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) has published the dataset “SMAPVEX16 Manitoba Core-Based In Situ Soil Moisture Data”, Version 1 from the Soil Moisture Active Passive Validation Experiment 2016 Manitoba (SMAPVEX 16 Manitoba) validation campaign. The new dataset contains in situ measurements of soil moisture and bulk density and is the first of many for the SMAPVEX16 Manitoba campaign. Though minimal documentation is presently available, the dataset is available as an early release.
NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the following Pre-Arctic-Boreal Vulnerability Experiment (Pre-ABoVE) datasets:

ORNL DAAC published the Vegetation Collection dataset “Lidar-derived Vegetation Canopy Structure, Great Smoky Mountains National Park, 2011”. This dataset provides multiple-return lidar-derived vegetation canopy structure at 30-meter spatial resolution for the Great Smoky Mountains National Park. Canopy characteristics were analyzed using high resolution three-dimensional point cloud measurements gathered between February-April 2011 for Tennessee and during March-April 2005 for North Carolina sections of the park. Vegetation types were mapped by grouping areas of similar canopy structure.
