2 ARM Facilities

3 Objectives: ARM Climate Research Facility Mission Summary Provide the national and international scientific community with the infrastructure needed for scientific research on global change Global change research includes the study of alterations to climate, land productivity, oceans, water cycle, atmospheric chemistry, and ecological systems

4 A DOE BER National User Facility Since 1990, the U.S. Department of Energy Atmospheric Radiation Measurement (ARM) Climate Research Facility, supported by the DOE Office of Science, unites the expertise of nine national laboratories: Argonne Lawrence Livermore Oak Ridge Brookhaven Los Alamos Pacific Northwest Lawrence Berkeley National Renewable Energy Sandia This partnership supports the DOE mission to provide for the energy security of the nation. This mission includes climate impacts of current and future energy production and developing solutions based on a sound energy strategy. In 2004, Facility was designated a DOE BER national user facility.

5 Capabilities and Deployment Locations 5 Fixed Sites in three vastly different climatic regions 2 mobile facilities that can be deployed worldwide Aircraft platforms for in-situ observations Off-site deployment capabilities that do not require a full complement of ARM instrumentation

6 Measurement Focused for Processes and Model Validation The ARM Climate Research Facility uses remote sensing instrumentation to make atmospheric (weather) observations and: supports the long-term operation of over 1,100 instrument systems in climatically important regions of the world; collects over 2,400 data streams per day, representing about 40 GB/ day; and Provides the quality data and its associated metadata to anyone through the ARM Archive for free. At the heart of the Facility, there are the 35 instrument scientists that know the capability and limitations of the ARM instruments. What do users want? Define the measurements (geophysical parameters) and then indentify the instrumentation and data processing.

7 ARM Data Flow: Data and Metadata, from Sensors to Users None of the ACRF facilities are located at a national Laboratory. The ACRF is a facility without walls: the great outdoors is our experimental environment. The ACRF provides the infrastructure to enable experiments to be conducted virtually. The Internet is our dataflow pipeline, connecting instrument data streams to users. What is needed real-time, what can wait? What is raw data, what is processed, and what is engineered?

8 North Slope of Alaska: Fixed Site Fixed site location: long-term measurements for context.

9 North Slope of Alaska Barrow (1997) Atqasuk (1999) Fixed Sites: Spatially representativeness issues.

10 ARM Mobile Facility Components To explore science questions beyond those addressed by ARM's fixed sites, researchers can use one of two ARM Mobile Facility (AMF). With instrumentation and data systems similar to the fixed sites, the AMF is designed to operate in any environment from the cold of the Arctic to the heat of the tropics for campaigns lasting a minimum of 6-24 months. The first AMF (AMF1) was deployed in 2005; the second AMF (AMF2) was deployed in Testing of specific science questions, but subject to context (need to avoid Golden Days syndrome, typical of field campaigns).

11 AMF 1: Transportable and Land-Based Deployments

12 AMF1 Niger 2006 Radiative Divergence using ARM, GERB, and AMMA Stations (RADAGAST) field campaign. To provide the first well-sampled, direct estimates of the divergence of solar and thermal radiation across the atmosphere.

13 AMF1 Facility Components Aerosols Surface Aerosol Observing System (AOS: Integrating Nephelometer operated at low RH, Integrating Nephelometer operated at RH scanned from ~40-90%, Particle/Soot Absorption Photometer 3-wavelength, Condensation Nuclei Counter, and Multiple-Supersaturation Cloud Nuclei and Condensation Nuclei Counter) Atmospheric Profiling Microwave Radiometer Profiler (MWRP 12-channel) Microwave Radiometer (MWR 2-channel) Microwave Radiometer (MWR 3-channel) Microwave Radiometer (MWR K-band) Microwave Radiometer (MWR W-band) Balloon-borne Sounding System (BBSS) Measurements needed at the appropriate temporal and spatial scales: synergism of observations approach

14 AMF1 Facility Components Clouds Micropulse Lidar (MPL) Microwave Radiometer (MWR) Narrow Field of View (NFOV) Radiometer Total Sky Imager (TSI) Vaisala Ceilometer (VCEIL) W-band (95 GHz) ARM Cloud Radar (WACR Scanning Cloud Radar W-band (95 GHz) Ka-band (35Ghz) Boundary Layer Cloud System (Ceilometer, Present Weather System, and Sunphotometer)

16 AMF2: Modular for Ship and Complex Terrain Deployments Modular, distributed systems Minimal footprint Instrument stabilization platforms for ship deployments

17 AMF 2 Steamboat Springs 2010 Storm Peak, Colorado Storm Peak Laboratory Cloud Property Validation Experiment (STORMVEX) to to obtain data about liquid and mixed-phase clouds.

18 RHUBC-II Off-Site Field Campaign 2010 The second phase of the Radiative Heating in Underexplored Bands Campaign (RHUBC-II) takes place on Cerro Toco, a mountain rising from the Chajnantor Plateau in Chile at an altitude of more than 5300 meters (17,400 feet) above sea level. Deployment of the Self Kontained Instrument Platform, or SKIP: begins latter this month. Scale back deployments to only what is needed.

19 Mobile Aerosol Observing System The MAOS is composed of two vans: aerosol measurements and chemistry Add well designed components that can be integrated into existing capabilities.

20 SUMMARY Design, build and operate your own complete (collect, process, and archive data) fixed site or mobile facility (expensive and takes time); or Indentify instruments and a data flow strategy, and piggy-back onto existing facilities to take advantage of existing infrastructure (cost effective and less time).
