 "description": "<DIV STYLE=\"text-align:Left;\"><DIV><DIV><P STYLE=\"text-align:Justify;margin:0 0 0 0;\"><SPAN>Carbon storage was calculated using two datasets in order to estimate above ground and below ground standing carbon stock. The first one is The National Biomass and Carbon Dataset 2000 (NBCD 2000). A high spatial resolution (30 m), year-2000 baseline estimate of basal area-weighted canopy height, aboveground live dry biomass, and standing carbon stock for the conterminous (lower 48) United States. One 16-bit signed raster layer at 30 m resolution. Digital numbers represent the amount of aboveground live dry biomass present in kg/m2 * 10. Thus, aboveground live dry biomass in kg/m2 = &lt;Digital Number&gt; / 10. Values were multiplied by 10 to preserve significant figures yet reduce file size. Units of kg/m2 were selected to coincide with FIA results/methodology. The units were converted to metric tons (tonnes) per hectare. To estimate the number of metric tonnes of biomass in a given region of interest/polygon, sum the values that NBCD2000 Mapping Zone lie within the polygon of interest and then multiply the result by 0.09 (which accounts for the fractional portion of a hectare present in a single 30 meter pixel).<\/SPAN><\/P><P STYLE=\"margin:0 0 0 0;\"><SPAN /><\/P><P STYLE=\"margin:0 0 0 0;\"><SPAN>The second dataset is the Gridded SSURGO (gSSURGO), similar to the standard product from the United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) Soil Survey Geographic (SSURGO) Database, but is in the Environmental Systems Research Institute, Inc. (ESRI®) file geodatabase format. The National Value Added Look Up (valu) Table database is designed to facilitate thematic mapping for several important soil properties and interpretations. The valu1 table within this database is a compilation of 57 pre-summarized or \"ready to map\" attributes derived from the soil survey geographic database, including soil organic carbon. The map unit average soil organic carbon values are given in units of grams carbon per square meter for 11 standard layer or zone depths. We used the entire soil depth. We converted both data sets to the same units and added them using Raster Calculator. To calculate the dollar value of carbon storage per grid cell = (Cabove + Cbelow) * $2/tonne/year.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
