    UPDATE of Land Forward Modeling
    Land cover data field
    By elevation we are preparing analysis of land cover using 30m TM-based land cover map of major vegetation types (eg evergreen forest, deciduous forest, grassland, etc) for our base ecosystem spatial mapping
    By elevation and vegetation type we are then assigning ecosystem (or biome) type classes which can be made to map to our current parameterizations of modeling types used in Century/Daycent calculations
    Will be taking first cut pass at the simulation of daily NEE, NPP, and ET for the regional domain based on 0.5 lat/lng gridding of daily climate
    These data are being processed and hopefully by late next week we will have a calculation for the domain which outputs daily NEE, NPP, and ET by ecosystem type
    MAP 1:
    Ecosystem mapping for domain
    MAP 2:
    Forest ecosystems broken down into simulation classes
    MAP 3a-d:
    DEM breakdown of ecosystem types
    Nest steps:
    Evaluate what is needed to calculate specific outputs and carbon dynamics for the project
    What spatial scale is needed for what evaluation?
    Selection of specific weather year to mimic 2004, given that we do not have 2004 weather we can use. Selection will be based on Peter Thornton's 1km 1980 to 2001 Daymet data base for the domain.
    Categories of data being used:
    DEM ranges to distinguish ecosystem types are:
    Elevational Zones (meters)
    Zone 1: 1400 - 2200
    Zone 2: 2200 - 2800
    Zone 3: 2800 - 3200
    Zone 4: 3200 - 4400
