Forcing ARM - Infrastructure

• Continuous field measurements and data products
  that promote the improvement of cloud science in
  climate models
• Currently supports three fixed facilities
• One mobile facility
• Deployed yesterday

6
Forcing ARM Infrastructure

• Successfully completed the Indirect and
  Semi-Direct Aerosol Campaign (ISDAC) to study
  properties of arctic aerosols during April and
  compare with those measured during the
  Mixed-Phase Arctic Cloud Experiment in October
  2004

Forcing ARM Science Program
Indirect Effect of Arctic Aerosols in the Infrared

• Barrow, Alaska NSA Site 6 years of CN
  measurements
• Increased Anthropogenic Aerosols during Arctic
  spring in Low level stratiform clouds leads to
  about 4 W/m2 increase in down-welling longwave
  radiation
• ? Warmer Arctic (surface lower atmosphere)ARM

Forcing ARM Science Program
Double ITCZ Problem alleviated JJA
Precipitation

• The Community Climate System Model (CCSM)
  predicted double rainfall bands due to spurious
  second ITCZ
• The ARM cloud parameterization was improved to
  avoid this spurious additional precipitation band
  across the pacific ocean

Active Chemistry in the Community Climate System
Model
Pioneering simulations of carbon, ozone, sulfur,
ammonia and development of interactive aerosol
effects for an Earth System Model

Time evolution of the model simulated ozone
mixing ratio (in ppbv), global and annual
average, at 10 hPa. The base simulation is in
red (solid and dash), the simulation with 1970
methane is in green and the simulation with 1970
CO2 levels and climatological SSTs is in blue.

  received for new solicitation on
  impacts/adaptation (850k/yr)
• Co-funded NAS Impacts, Adaptation, Vulnerability
  workshop
• Work continues on scenarios and coordination
  between the IAM, ESM, and IAV communities for a
  potential IPCC 5th Assessment
• Co-funded planned (July 21-22) ANL/University
  Workshop on uncertainty methods in IA
• US CCSP Principals briefed on ORNL study to
  inventory U.S. and international climate change
  impacts/adaptation research

  modeling capabilities using combined elements of
  models

16
Climate Change Mitigation

• CSiTE Paradigm
• Scientific and technological advances are
  possible that will significantly impact the
  development of improved strategies for the
  enhancing C sequestration in terrestrial
  ecosystems
• CSiTE Goals
• Discover characterize links between critical
  pathways mechanisms for creating larger and
  longer-lasting C pools in terrestrial ecosystems
• Establish the scientific basis for enhancing C
  capture and long-term C sequestration in
  terrestrial ecosystems by developing
• Scientific understanding of C capture
  sequestration mechanisms in terrestrial
  ecosystems across multiple scales from the
  molecular to landscapes
• Conceptual and simulation models for
  extrapolation of process understanding across
  spatial temporal scales
• Estimates of C sequestration potential
  nationally, leading to global estimates
• Assessments of environmental impacts economic
  implications of C sequestration
• CSiTE Approach
• Consortium of Labs implement field and Laboratory
  investigations (ORNL, ANL, PNNL)
• Field research focuses on switchgrass systems in
  concert with Biofuels Program
