Digital Elevation Model, 0.25 m, Barrow Environmental Observatory, Alaska, 2013

Cathy Wilson & Garrett Altmann
This 0.25m horizontal resolution digital elevation model, DEM, was developed from Airborne Laser Altimetry flown by Aerometric Inc, now known as Quantum Spatial, Inc. on 12 July, 2013. One Mission was flown and the data jointly processed with LANL personnel to produce a 0.25m DEM covering a region approximately 2.8km wide and 12.4km long extending from the coast above North Salt Lagoon to south of Gas Well Road. This DEM encompasses a diverse range of...

Plant Root Characteristics and Dynamics in Arctic Tundra Ecosystems, 1960-2012

Colleen Iversen, Victoria Sloan, Patrick Sullivan, Eugenie Euskirchen, David McGuire, Richard Norby, Anthony Walker, Jeffrey Warren & Stan Wullschleger
Plant roots play a critical role in ecosystem function in arctic tundra, but root dynamics in these ecosystems are poorly understood. To address this knowledge gap, we synthesized available literature on tundra roots, including their distribution, dynamics, and contribution to ecosystem carbon and nutrient fluxes, and we highlighted key aspects of their representation in terrestrial biosphere models. Across all tundra ecosystems, belowground plant biomass exceeded aboveground biomass, with the exception of polar desert tundra. Roots...

Simple Ontology Format (SOFT)

Alexandre Sorokine
Simple Ontology Format (SOFT) library and file format specification provides a set of simple tools for developing and maintaining ontologies. The library, implemented as a perl module, supports parsing and verification of the files in SOFt format, operations with ontologies (adding, removing, or filtering of entities), and converting of ontologies into other formats. SOFT allows users to quickly create ontologies using only a basic text editor, verify it, and portray it in a graph layout...

ARM Navigation Best Estimate 10 Hz (NAVBE) and 1-min (NAVBE1M) Value Added Products (VAP) for Ship Deployments

Tami Toto, Michael Jensen & Mary Bartholomew
The Navigation Best Estimate (NAVBE) VAP was developed in response to the 2012-2013 Marine ARM GPCI Investigation of Clouds (MAGIC) deployment, the first ship-based deployment of the second ARM Mobile Facility (AMF2). It has since been applied to the 2015 ARM Cloud Aerosol Precipitation EXperiment (ACAPEX) deployment. A number of different instruments on the ships collected Global Positioning System (GPS) and Inertial Navigation System (INS) measurements during the MAGIC campaign. The motivation of the NAVBE...

Watershed impervious cover relative to stream location

James Wickham
Estimates of watershed (12-digit huc) impervious cover and impervious cover near streams and water body shorelines for three dates (2001, 2006, 2011) using NLCD data. Differences between watershed impervious cover and impervious cover near streams can be used to assess the spatial pattern of impervious cover within a watershed.

internet_outage_adaptive_a21j-20150702 (07/02/2015 to 10/01/2015)

University Of Southern California-Information Sciences Institute
To collect this data, all allocated and responsive Internet IP address blocks were pinged by sending ICMP ECHO_REQUEST (PING) packet. The block status was recorded in this data set. Probe was repeated every 11 minutes, and more quickly when uncertain about block status. In all, approximately 3.5M /24 subnets were periodically probed.
