Study of the cost and cost-efficiency the combined two-phase multi source inventory of carbon stock and carbon stock changes

The cost and cost efficiency estimates within the bottom-up approach of the CarboInvent project were applied in all test sites. Basically the sampling error of the different national inventories was related to the costs for the applied in situ samples and to the results of the stratified samples. The aim was to show the gain in precision with respect to assessment costs for each design alternative. The application of EO data as stratification source proved to be an efficient method to reduce the sampling error with relatively low additional costs. The effect could be shown especially for high in situ measurement costs and even with relatively high EO data acquisition costs. Very low in situ costs might be combined with EO stratifications depending on inventory size and intensity.
