Breakout 3 List and prioritize biological and environmental measurements that ideally should be made at each NPN site.
Strong Recommendation Collocate with NERON (and other opportunities if at all possible) Strong endorsement from Ken Crawford and Sharon Le Duc Use ex-COOP volunteers for NPN observations! Commissioning of new NERON stations will begin in Summer, 2006 (with minimum 2 year transition from volunteer operated to automated) This is a natural window for us to coopt their volunteers to serve as NPN observers Julio offered a model of “ instrumented phenological obs sites at NERON locations ”, with intensive citizen- scientist/volunteer networks around them This may serve as a model for co-location with Ameriflux sites (about 90 in US), LTERs, National Parks, … OR perhaps one of the others would be easier to start from?
A Strategy Additional Measurements <---- weight by relevance to each use & difficulty/expense----> Uses of NPN observations (EPN offers good initial list) Advance science of phenology Human health Climate monitorin g Inputs to weather & climate models Agricultur e Carbon … T P Solar Soil moisture Soil T CO2 … The product of the x vs y weights for each cell allows prioritization.
Wishlist Observations at collocated NERON/NPN sites Continuous: Temperature* Precipitation* Relative Humidity** Direct vs. diffuse insolation Wind** Global Radiation** Soil moisture** [CO2], [O3] Soil temperature** Snow depth/swc *(the primary remaining role for volunteers in NERON future) Webcam of plant ? (including possibility of movable IR filters) Occasional: First frost/hard freeze Assorted freeze/thaw Leaf optical/spectral properties (Hand-held radiometry of plant) Leaf biochemistry? Soil chemistry (e.g., nitrogen) Surrounding species & abundance lists 360 º photos of setting & plant* * will be collected by NERON ** may be collected by NERON (if not, we would want to add) ( ) We need to add for NPN
Observations at minimal* NPN sites Continuous: Temperatures, soil & air Soil moisture Next on list: global solar (would it be possible to arrange for a small solar panel to act as both a power supply & crude pyranometer?) Annual: Soil chemistry 360 º photos of setting & plant How to keep track of water applied? Observations at pheno-watch (random- contribution*) sites Continuous: None? “ Annual ” : Some minimum meta-data * Disastrous terminology point!
(Wishlist) Site Characterization at as many sites as possible* Regularly (on site): Site characteristics (evolving metadata): canopy topography elevation plant community plant size soil type & chemistry surrounding land use history Heterogeneity of the above characteristics over the site “ footprint ” (representativeness) --how to get at this is still research Surrounding characteristics (360 º photos) Possible supporting characterizations/obs (not well received in plenary): Invasives – presence/absence Snowmelt/runoff observations Motion/audio detectors for animals Lake/river freeze/thaw Leaf biochemical properties * Disastrous terminology point!
Site Characterization at as many sites as possible Satellite observations Synoptic scale observations (we need to arrange for essentially full remote-sensing coverage of the pixels containing our sites as often as possible to develop coincident RS/in situ obs) VI LAI/fPAR LST High resolution spectra (radiometry) – leaf optical properties by hand-held Pheno-spectral library for different plant communities/locations from overflights or satellites -- a plant parallel to USGS mineral spectral libraries at different phenological stages (~monthly)
Other Considerations Need full season observations and not be hung up on start of season Look at the GLOBE program for protocols/reporting schemes Need to develop a protocol for what area constitutes the “ site ” and how big is its “ setting ” ; also need to acquire or develop protocol for microscale plant selection and site (exactly where should index plants be placed, which native plants are the preferred “ ones ” within a given park?)--GLOBE may have guidance for this These observations probably must vary from site to site, depending on location – perhaps there will be different levels of sites (some with more detailed observations) A tension between perspectives: Remote sensors: As many sites as possible, quality be damned Modelers: Highest quality possible, even if only at a few sites … local redundancies are necessary to achieve this
More Considerations Animal observations represent an additonal form of phenology AND key info about the setting that the “ observatory plants ” are growing in; thus may be important to include even in a plant-based network (including encouraging collocated insect traps?) Plant size histories (e.g., biomass, height, diameters) need to be incorporated into the protocol somehow (webcam, 360 photos, tape measures, dendrometers, whatever works) QC on volunteer observations must be a real priority! Pilot and/or super sites are to be encouraged, with obs beyond even our wishlists!
