The Making Earth System Data Records for Use in Research Environments (MEaSUREs) Greenland Ice Velocity: Selected Glacier Site Velocity Maps from interferometric synthetic aperture radar (InSAR) dataset at NSIDC DAAC has been updated with velocity maps for 2016. This release, Version 1.2, includes new browse images, metadata files, and more descriptive file names, and fills in some missing 2015 files.
NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) Common Metadata Repository (CMR) project team completed an effort to update and consolidate collection-level metadata export to CMR with single service. With this release, all collection-level metadata for datasets managed within ECS are being exported to CMR using ISO 19115. This project accomplished both a reconciliation of metadata in CMR as well as an improvement to metadata export services and workflows. Included in this phase of work was the transition to the new Earth Science Data Type (ESDT) process, which enables the DAAC to locally generate ESDTs from metadata contained in CMR. The new ESDT process will reduce the time to ingest new data products into ECS.
NASA IceBridge High Capability Radar Sounder (HiCARS) 2 L1B Time-Tagged Echo Strength Profiles data are now available from NSIDC DAAC. This dataset contains Antarctica echo strength profiles from the HiCARS Version 2 instrument.

ORNL DAAC
NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the following datasets to its online archive:
- Pre-Arctic-Boreal Vulnerability Experiment (Pre-ABoVE): Land Cover and Vegetation Map, Arctic National Wildlife Refuge. ORNL DAAC, Oak Ridge, Tennessee, USA.
- Daymet: Station-Level Inputs and Model Predicted Values for North America, Version 3. ORNL DAAC, Oak Ridge, Tennessee, USA.
ORNL DAAC published Snowmelt Timing Maps Derived from Moderate Resolution Imaging Spectroradiometer (MODIS) for North America, 2001-2015: This dataset provides snowmelt timing maps (STMs), cloud interference maps, and a map with the count of calculated snowmelt timing values for North America. The STMs are based on the MODIS standard 8-day composite snow-cover product MOD10A2 for the period 2001-01-01 to 2015-09-06. The STMs were created by conducting a time-series analysis of the MOD10A2 snow maps to identify the DOY of snowmelt on a per-pixel basis. Snowmelt timing (no-snow) was defined as a snow-free reading following two consecutive snow-present readings for a given 500-m pixel. The count of STM values is also reported, which represents the number of years on record in the STMs from 2001-2015.
ORNL DAAC published the Carbon Monitoring System (CMS) Global 0.5-deg Wetland Methane Emissions and Uncertainty (WetCHARTs v1.0) dataset: This dataset provides global monthly wetland methane (CH4) emissions and uncertainty data products derived from an ensemble of multiple terrestrial biosphere models, wetland extent scenarios, and CH4:C temperature dependencies. The data are at 0.5 by 0.5-degree resolution. Two model output data products are included in WetCHARTs v1.0: an output from the full ensemble for 2009-2010 and an output from a limited subset for 2001-2015. The intended use of the products is as a process-informed wetland CH4 emission and uncertainty dataset for atmospheric chemistry and transport modelling (WetCHARTs).
ORNL DAAC published the dataset Tree Mortality from Fires and Bark Beetles at 1-km Resolution, Western USA, 2003-2012. This dataset provides annual estimates of tree mortality due to fires and bark beetles from 2003 to 2012 on forestland in the continental western United States.
