This observatory includes three eddy covariance sites, eleven stream gages, 18 sap flow sensors, numerous lysimeters and soil moisture probes, a new snow pillow and cosmic ray sensor, 13 stream gages, several met stations, and collection of biomass, soil, and water samples from sites in NM. We also completed a special issue in the journal Ecohydrology (October 2008) describing the results from our observatory. Plans for the upcoming year: We will continue operation of the eco-hydrological environmental observatory in New Mexico while building and strengthening linkages to other observing efforts in the western U.S. We will explore the potential for a second special issue describing the further results from these efforts PARTICIPANTS NAME CATEGORY INSTITUTION Roger Bales  Faculty  University of California, Merced  Patrick Broxton  Graduate student  University of Arizona  Joseph Gustafson  Graduate student  University of Arizona  Shirley Kurc  Faculty  University of Arizona  Marcy Litvak  Faculty  University of New Mexico  Joseph McConnell  Faculty  Desert Research Institute  Noah Molotch  Faculty  University of California, Los Angeles  Jonathan Petti  Other research scientist  University of Arizona  Eric Small  Faculty  University of Colorado  Everett Springer  Other research scientist  Los Alamos National Laboratory  Peter Troch  Faculty  University of Arizona  William Veatch  Graduate student  University of Arizona  Enrique Vivoni  Faculty  Arizona State University  PARTNERS / ORGANIZATIONS Los Alamos National Laboratory Organization Involvement: N/A Shared Resources / Joint Activities: N/A Location: Los Alamos, NM, USA URL: N/A Valles Caldera National Preserve Organization Involvement: N/A Shared Resources / Joint Activities: N/A Location: Valles Caldera, NM, USA URL: N/A National Center for Atmospheric Research Organization Involvement: N/A Shared Resources / Joint Activities: N/A Location: Boulder, CO, USA URL: N/A MEDIA / PUBLICITY None reported   ©2004 SAHRA.
