The Calculation Models are a set of modules for creating structured data models from LCA observations and evaluating biogeochemical aspects of specific farming cycles.
HESTIA provides open-source environmental models that run automatically on uploaded data. This section explains how the models work, how they are orchestrated, and how to interpret their output.
These models assign default method classifications to Measurements, group related Measurements, and process Measurement values.
These models gap-fill Management onto a Site.
These models gap-fill Measurements onto a Site.
These models gap-fill Infrastructure and related Input onto a Site.
These models calculate dates and durations for Cycles and their primary and other Sites.
These models determine whether each input category has been fully recorded and set boolean flags that control which emission models run.
These models gap-fill land cover from crop/forage products and set default practice values from lookup tables.
These models process animal properties, milk yield, and link animal feed inputs to background data.
These models process input values, link to HESTIA aggregated background data, and carry forward properties.
These models process product values and gap-fill crop residues.
These models return emissions from excreta Transformations to the parent Cycle.
These models calculate information about the transportation of inputs and products.
These models remove superseded emission records after recalculation.
These models determine the allocation method, calculate economic value shares, and assign classifications to the Impact Assessment.
These models collect and prepare all emissions from the Cycle for impact characterisation.
These models collect and prepare resource use data from the Cycle for impact characterisation.
These models assign characterised impact results to individual products based on the allocation method.
