CHARMe - About
A challenge faced by users of climate data is how to judge whether the data are fit for purpose. This challenge is a serious impediment to widening the use of climate data by both expert and non-expert users for diverse applications. Different users require different kinds of supporting information; we term this 'Commentary' metadata. For this project, we define the scope of Commentary metadata to include:
- Post-fact annotations, e.g. citations, ad-hoc comments and notes
- Results of assessments, e.g. validation campaigns, intercomparisons with models or
other observations, reanalysis, quantitative error assessments
- Provenance, e.g. dependencies on other datasets, processing algorithms and chain, data
- Properties of data distribution, e.g. data policy and licensing, timeliness (is the data
delivered in real time?), reliability
- External events that may affect the data, e.g. volcanic eruptions, El-Nino index, satellite
or instrument failure, operational changes to the orbit calculations
This definition encompasses both quantitative and qualitative metadata.
The duration of this project is twenty-four months, and commenced in January 2013.
