dc.description.abstract | This document constitutes Deliverable 5.5 of the JERICO project. It is intended to furnish
members of the JERICO community with a basic understanding of how to proceed when
attempting to establish measurement uncertainty for marine temperature, salinity and
chlorophyll-a sensors. The document presents descriptions of the three measurands from a
metrological standpoint, and discusses the approaches that could be taken to prepare
uncertainty budgets for relevant sensors with some suitable examples and useful advice.
The estimation of the uncertainty associated with the results of a measurement is an
objective way to numerically depict the trustworthiness of those results. It is, therefore, a
crucial part of the measuring process.
Any measured value can be considered complete only if accompanied by a relative estimate
of uncertainty. However, the latter characteristic is rarely discussed in marine observing
circles and in the marine data management community despite its intimate link to sensor
performance, data quality and data usability issues. This disregard arises from ignorance
concerning the rigor required of modern measuring activity and the complexity of the
underlying metrological system supporting it.
There is a pressing need to begin to address this state of affairs, and the present publication,
intended as a guidance document for members of the JERICO community, is a first step. The
document deals with outlining a possible approach to determining uncertainty for sensor
measurements of seawater temperature, salinity and chlorophyll-a. The approach is based on
the generally accepted methodology for uncertainty evaluations given in the BIPM (Bureau
International des Poids et Mesures) publication “Evaluation of measurement data - Guide to
the expression of uncertainty in measurement”, commonly referred to as the GUM (2008).
In all three cases, the conceived blueprint for action is based on the following topical
cornerstones: the specification of the measurand, the descriptions of the realized quantity
and the relative reference value, and finally, the identification of the uncertainty components
and the quantification of the uncertainty.
The present document is intended to be used in conjunction with the GUM, which continues
to remain the master reference document for the evaluation of uncertainty in measurement at
this time. | en_US |
