ARM Mobile Facility Now in the Black Forest, Germany ARM Climate Research Facility Locations
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 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 ( ) SHEBA ( ) *About two dozen have taken place at the NSA
