Abstract
Given the significance of national carbon inventories, the importance of large-scale estimates of carbon stocks is increasing. Accurate biomass estimates are essential for tracking changes in the carbon stock through repeated assessment of carbon stock, widely used for both vegetation and soil, to estimate carbon sequestration. Objectives: The aim of our study was to determine the variability of several aspects of the carbon stock value when the input matrix was (1) expressed either as a vector or as a raster; (2) expressed as in local (1:10,000) or regional (1:100,000) scale data; and (3) rasterized with different pixel sizes of 1, 10, 100, and 1000 m. Method: The look-up table method, where expert carbon content values are attached to the mapped landscape matrix. Results: Different formats of input matrix did not show fundamental differences with exceptions of the biggest raster of size 1000 m for the local level. At the regional level, no differences were notable. Conclusions: The results contribute to the specification of best practices for the evaluation of carbon storage as a mitigation measure, as well as the implementation of national carbon inventories.

Ecosystems regulate the global climate by storing greenhouse gases
The process of carbon sequestration decreases the concentration of CO2 during photosynthesis; the majority of carbon is returned to the atmosphere through autotrophic and heterotrophic respiration [1,2], part of it becomes effectively locked in plant tissues during the growth of biomass [3,4] and in soil complexes [1]
Comparing the carbon stock in the same area, with the Detailed Combined Layer used on the local scale, the assessed carbon stock was higher than with the Corine Land Cover vector data used on the regional scale, namely by 6.1% in the Všemina catchment, by 6.6% in the Drevnice catchment, and by 5.7% in the Czech Republic
Summary
Ecosystems regulate the global climate by storing greenhouse gases. The process of carbon sequestration decreases the concentration of CO2 during photosynthesis; the majority of carbon is returned to the atmosphere through autotrophic and heterotrophic respiration [1,2], part of it becomes effectively locked in plant tissues during the growth of biomass [3,4] and in soil complexes [1]. Carbon-stock estimation is a basis for modeling carbon productivity and sequestration [10,11] These are mainly for regional-scale carbon models [12,13] or for models assessing trajectories in biomass trends such as LandTredr [14,15], or large-scale sequestration models such as the InVest model [4], which is widely used for regional or national studies [16,17,18]. Carbon-stock assessment is necessary for the creation of stored carbon and carbon-sequestration maps, which are useful tools for providing decision-making support [19] to prevent carbon-rich ecosystems from becoming carbon sources [20] as a consequence of inappropriate management or land-cover changes, e.g., deforestation [9]
