Yosemite Valley, California
Suggested near-term Yosemite climate priorities (2004 YHMW)2005 Status
Full communications to all sites along 120 corridor(in fact, all hydromet sites anywhere in and near the park)
About the same, will add another GOES antenna at Gin FlatMore all-weather (liquid & frozen), live, quality automated precipitation measurements (now: Gin Flat, Tuolumne Meadows)
Hodgdon Meadows Geonor, Tuolumne Meadows Water TankHigh elevation: (Mt Warren, Mt Hoffman) (all but precip)
Mt Warren ready all summer, helicopter dependentAutomated, live, full-complement Yosemite Valley site
Still on the listSeveral benchmark sites (complete hydro and energy budget, well exposed, permanent, reference-quality climate stations)(e.g.: Gin, Dana, Crane Lookout, Valley, Tenaya/Tuolumne, Hodgdon/Crane Flat)
Retain historical manual NWS valley cooperative station
Augment instrumentation at north Yosemite sites
RAWS Stations for Wawona and El Portal in the works

NATIONAL PARKS OMNIBUS MANAGEMENT ACT OF 1998
“The Secretary shall undertake a program of inventory and monitoring of National Park System resources to establish baseline information and to provide information on the long-term trends in the condition of National Park System resources. The monitoring program shall be developed in cooperation with other Federal monitoring and information collection efforts to ensure a cost-effective approach.”
“The Secretary shall … assure the full and proper utilization of the results of scientific studies for park management decisions.
NPS Inventory and Monitoring Program
• Determine the status and trends in selected indicators of the condition of park ecosystems to allow managers to make better-informed decisions and to work more effectively with other agencies and individuals for the benefit of park resources.
• Provide early warning of abnormal conditions of selected resources to help develop effective mitigation measures and reduce costs of management.
• Provide data to better understand the dynamic nature and condition of park ecosystems and to provide reference points for comparisons with other, altered environments.
• Provide data to meet certain legal and Congressional mandates related to natural resource protection and visitor enjoyment.
• Provide a means of measuring progress towards performance goals.
WRCC Project 2005-06 Goals
• Complete the weather/climate data inventory of each of the 32 I&M Networks (a total of about 270 park units)
• Produce and assist in production of network-specific reports
• Develop and populate a database documenting weather stations in and near I&M Parks
• Evaluate adequacy of coverage and identify major information gaps
• Evaluate existing weather and climate monitoring protocols
• Produce templates for monitoring protocols that can be adopted and individualized by other parks
• Begin development of network and park specific web pages to access, display, manipulate and summarize data
• Finish this by Autumn 2006
