ARM Atmospheric Radiation Measurement DOE’s Flagship Global Climate Change Program ARM Climate Research Facilities in Alaska The North Slope of Alaska Team at Sandia Labs/NM: Bernie Zak, Jeff Zirzow, Kathy Anguiano, Jean Lewis, Mark Ivey ARM Overview: Goals Improve Climate Predictions Improve Global Climate Models - Radiative Transfer w/Clouds - Treatment of Clouds File.50 ARM Climate Research Facility Locations ARM Mobile Facility Now in the Black Forest, Germany ARM Sites Taken Together Form a National User Facility: ARM Climate Research Facility (ACRF) -Open to All on a Proposal Basis -Uses Not Limited to Climate Research -Number of Users is the Figure of Merit -No Sunset Date for ACRF -Use Fees Limited to Additional Costs North Slope ARM Climate Research Facility: Where Climate Change is Most Rapid Categories of Instrumentation* -Surface Meteorological Sensors -Wind, Temperature and Humidity Profilers -Cloud Observation Instrumentation -Downwelling Radiation Sensors -Upwelling Radiation Sensors -Aerosol Instrumentation -Gas Instrumentation *About 70 sensors in all (on the North Slope), including radars, lidars, spectrometers, imagers, etc. etc. Selected NSA ACRF Field Experiments* • Upcoming: Indirect and Semi-Direct Aerosol Campaign (2008) • International Polar Year 2007-09 • IR Loss (On-going, 2006) and RHUBC, 2007 • Boundary Layer Cloud (2005) • Mixed-Phase Arctic Cloud (M-PACE 2004) • NASA AIRS Validation (2002-ongoing) • Arctic Winter Water Vapor (2001, 2004) • Aerosonde Robotic Aircraft (1999-2005) • SHEBA (1997-98) *About two dozen have taken place at the NSA Barrow ACRF Facility: “Great White” Atqasuk Barrow ‘Duplex’ and Visiting ARM Scientists
