Presentation transcript:

Highlights 2006: MDN/Hg in Air  Truly the last year of planned monitoring  Precipitation collection (wet deposition only)  One of four CA sites (added Sequoia NP July 2003, Converse Flats Apr 2006, Yurok Tribe-Requa Aug 2006, Covelo closed 2001)  2005 cumulative wet deposition similar to previous years (2000, 2003)  Mini study by USEPA Region IX in Guadalupe  Hg air NASA and Calero

Highlights 2006: MDN

Results: MDN San JoseSequoia 2 nd half ng/m m precip 17.7 ng/L (3600 ng/m ng/L all year) 2560 ng/m m precip 4.87 ng/L ng/m m precip 7.88 ng/L 1740 ng/m m precip 4.22 ng/L ng/m 2.431m precip 8.26 ng/L 6415 ng/m m precip 4.98 ng/L

Results: NASA vs Calero Concentrations  NASA not directional, Calero max from W

Plan 2007: MDN/Hg in Air  Analyze and summarize San Jose data  MDN reporting generally ~6 months behind  Draft tech report early Q2 in ’07, final Q3  Follow up Guadalupe Watershed Air Data?  Dependent on Region IX mobile lab willingness/ availability
