China: Zhang_Bei
2005 Funtional Type Land Cover Type: Grass
Compare all MODIS Land Cover Types for Zhang_Bei
Current value per hectare: $57.4
This chart shows the dollar value of carbon sequestration by vegetation per hectare per year for Zhang_Bei, based on NPP data. In the most recent year, one hectare of vegetation at this site sequestered sufficient atmospheric carbon to place its vegetation value at $57.4, given a sequestration cost of $10 per metric ton. See chart below for previous years' sequestration values.
ValueA=NPP/∑GPP ratio-derived NPP values per Zhang et al. NPP/∑GPP ratio: 0.6
ValueB=NPP per MODIS. See Calculations page for more information.
Graph body = NPP Values A & B, lower graph = NDVI (Normalized Difference Vegetation Index)

Zhang_Bei Fill Value Log
Quality flag data as incorporated in pixel reliability notations results in fill value replacement in source datasets. Fill values (indicating substandard pixel reliability) are disregarded in generating annual averages. Please use caution when source datasets include a substantial number of fill values. For this site's dataset, the following fill value data points were encountered:
