Accelerated Climate Modeling for Energy (ACME) – Atmospheric Radiation Measurement (ARM) Climate Research Facility – Atmospheric System Research (ASR) Coordination Workshop, October 21–22, 2015

The Climate and Environmental Sciences Division (CESD) of the U.S. Department of Energy’s Office of Biological and Environmental Research focuses on advancing a robust predictive understanding of Earth’s climate and environmental systems to inform the development of sustainable solutions to the Nation’s energy and environmental challenges. CESD climate activities related to atmospheric processes include: observations through the Atmospheric Radiation Measurement (ARM) Climate Research Facility; atmospheric research and model parameterization development through the Atmospheric System Research (ASR) program; climate model development and climate research through the Accelerated Climate Modeling for Energy (ACME) project along with other computationally focused model-development activities within the CESD Earth System Modeling (ESM) program, and development of robust model analytical and testing frameworks at multiple scales through the Regional and Global Climate Modeling program. This workshop focused primarily on improving model treatment of atmospheric processes as a means to focus discussion and did not address research on terrestrial ecosystem and subsurface processes, which are also part of the CESD research portfolio.

Robotic arm development platform

A robotic arm development platform will provide the tools for SRNL to increase its competency in this area and allow customer demonstrations to be performed so they can visualize how the technology relates to their application. The objective is to set up an adaptable development platform that can easily be re-configured for a variety of demonstrations for collecting data that will help engage the customer. Collaborative robots are designed with built in features allowing them to safely operate alongside employees.

Aerosol and Cloud Optical Properties from the ARM Raman Lidars: The Feature Detection and Extinction (RLPROF-FEX) Value-Added Product

Aerosols and their interactions and influence on clouds are among the main sources of uncertainties in radiative direct and indirect forcing (IPCC 2013). Continuous height-resolved measurements of cloud and aerosol optical properties are needed to reduce these uncertainties. Here we describe the Raman Lidar Profiles – Feature detection and Extinction (RLPROF-FEX) Value-Added Product (VAP) derived using Raman lidar data at multiple U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) user facility sites. RLPROF-FEX provides estimates of extinction, backscatter, and depolarization using the algorithm described by Thorsen et al. 2015 and Thorsen and Fu 2015. This document provides a description of the FEX algorithm, its input and output data, and related details about the Raman lidar (RL) system.

Concrete Inspection in Remote Areas with Robotic Arms

The use of non-destructive examination (NDE) to assess the conditions of concrete structures has received extensive attention in recent years. NDE analysis techniques are used to evaluate the properties of materials and to ensure the integrity of structures without causing damages to them. NDE inspection is often performed manually by certified technicians, however in remote and high hazard environments this is impossible or undesirable for human safety. Development of remote and robotic technologies to perform these essential inspections is of interest to the DOE EM complex due to its aging infrastructure and hazardous environments. This goal of this seedling was to develop techniques to remotely examine inaccessible concrete structures and to evaluate results collected remotely to those obtained by human hand. Additionally, two promising state of the art NDE instruments were identified to be used for the characterization to include the new Proceq Ground Penetrating Radar (GPR) which generates results in 3D using Augmented Reality. A test bed was built to develop and evaluate deployment techniques of the NDE instruments with a robotic arm. Concrete test forms simulating the rough concrete surfaces, strength, composition and potential structural defects that can be found at our DOE EM facilities were built for the examination. Initial NDE instrumentation data collection has been performed on the concrete test forms.
