The Certify API allows you to add measurement samples to your project. Measurement samples are used to represent a set of physical measurements that you have taken of the carbon removal process. For instance, these could be chemical analysis of soil, flue gas analyses or feedstock analyses.
Datapoints and measurement samples are closely related but measurement samples can contain many different values, whereas datapoints only contain one. Whereas datapoints are only used in crediting calculations, measurement samples can be used in both crediting and in the data quality assessment.
A measurement sample can have multiple pieces of metadata associated with it, such as the date and time of the measurement, the location of the measurement and the measurement type. The measurement type tells us what physical substance is being measured, such as soil, flue gas or feedstock. Measurement types are specific to pathways, so you should look for measurement types that are specific to the pathway you are working with. We currently support two pathways - enhanced weathering and biochar. Each individual measurement in a sample has a property which describes the physical parameter being measured.

​
Measurement properties

A measurement property is made up of two parts - a quantity kind and a qualifier. Each measurement type has an allowed list of measurement properties which are shown below.

​
Quantity kind

The quantity kind describes what physical parameter is being measured. For example, mass fraction or temperature is a quantity kind. The QuantityKind enum in the API schema lists all the possible quantity kinds. Quantity kind is based around ideas from the QUDT project.

​
Qualifiers

Some properties need more information to fully describe the measurement than just the quantity kind. In this case, we can add an extra qualifier to the property which tell us more about the measurement. For instance, for a mass fraction quantity kind, we might add a qualifier to say that the measurement is a mass fraction of a specific element.
