Future Steps - Schedule, Deliverables (continued)
3. During year 3, we propose to improve the estimates of the impacts of Development on carbon sequestration in three different ways:
     1). We will use MODIS NPP and LAI products to analyze the effects of development on carbon budgets

Gross primary production computed from MODIS data over the conterminous U.S.

     2). We will also use estimates of development derived from regressions developed by NGDC in BGC model runs. Our current estimates reflect gross impacts of development on the carbon budgets using the USGS MRLC classification scheme. Specifically, we would like to simulate NPP of lawns, parks etc. and add these amounts to the total NPP. Our current estimates do not reflect this amount.

     3) Finally, we will run our simulation model on a distribution of land covers in each eco-region instead of dominant land cover as was done in year 2.

4. During year three USGS and NGDC will collaborate on the development of methods for estimating the percent cover of impervious man made surfaces from Landsat 7 data. USGS will use the air photo point count estimates of the percent development to evaluate the accuracy of the estimates made from Landsat 7 data.
