A chemical flow into water, soil, or air.
Field | Type | Required | Definition |
---|---|---|---|
term | Term | Yes |
A reference to the Term describing the Emission. |
description | string | No |
A description of the Emission. |
value | array[number|null] | Yes |
The quantity of the Emission. If an average, it should always be the mean. Can be a single number (array of length one) or an array of numbers with associated dates (e.g. representing multiple measurements over time). |
sd | array[number|null] | No |
The standard deviation of value. |
min | array[number|null] | No |
The minimum of value. |
max | array[number|null] | No |
The maximum of value. |
statsDefinition | string | No |
What the descriptive statistics (sd, min, max, and value) are calculated across, or whether they are simulated or the output of a model. Spatial is descriptive statistics calculated across spatial units (e.g., pixels) within a region or country. Possible values are: |
observations | array[number|null] | No |
The number of observations the descriptive statistics are calculated over, if different from the numberOfCycles specified in Cycle. |
dates | array[string] | No | |
startDate | string | No | |
endDate | string | No | |
emissionDuration | number | No |
The duration of the Emissions in days, particularly used for measured Emissions. |
depth | number | No |
For soil Emissions, the depth at which the Emissions was recorded in centimeters. |
properties | List[Property] | No |
A list of Properties of the Emission, which would override any default properties specified in term. |
methodModel | Term | Yes |
A reference to the Term describing the method for measuring the Emission or the model used to calculate it. |
methodModelDescription | string | No |
A free text field, describing the method for measuring the Emission or the model used to calculate it. |
methodTier | string | Yes |
Background data are drawn from existing datasets such as ecoinvent and not modelled specifically here. Measured data are direct measurements of an Emission. Tier 1 methods use global parameters without any regional specificity (e.g. a global factor for the N2O emissions from synthetic fertilizer). Tier 2 methods are models with geographically specific parameters. Tier 3 methods are geographically specific models with time-steps. Possible values are: |
inputs | List[Term] | No | |
operation | Term | No | |
transformation | Term | No |
For Emissions created during a Transformation, the Term describing the Transformation. |
source | Source | No |
A reference to the Source of these data, if different from the defaultSource of the Cycle. |
Internal Properties
Field | Type | Definition |

@type | string | Emission |
schemaVersion | string |
The version of the schema when these data were created. |
added | array[string] |
A list of fields that have been added to the original dataset. |
addedVersion | array[string] |
A list of versions of the model used to add these fields. |
updated | array[string] |
A list of fields that have been updated on the original dataset. |
updatedVersion | array[string] |
A list of versions of the model used to update these fields. |
aggregated | array[string] |
A list of fields that have been 'aggregated' using data from multiple Cycles. |
aggregatedVersion | array[string] |
A list of versions of the aggregation engine corresponding to each aggregated field. |
deleted | boolean |
Indicates if this emission has been marked as deleted from the original dataset. |
