Overview
In the LinkedEarth context, a working group (WG) is a self-organized coalition of knowledgeable experts, whose activities are governed herewith. This page is dedicated to the discussion of data and metadata standards for the uncertainty associated with ChronData and PaleoData.
Members of 'Uncertainty Working Group'
This working group has 6 members.
Specific Task
We recommend that the discussions focus on the following considerations, and explore potential commonalities.
For each variable type, we recommend:
- structuring discussions about how uncertainty can affect the scientific questions one would want to ask of the data.
- Listing essential, recommended, and optional uncertainty information for:
- The measurements themselves
- The inferred climate information
- Providing an ideal template to report uncertainty in paleoclimate studies.
- Providing separate recommendations for new and legacy datasets
- Thinking about how the rest of the paleoscience community, or other (non)scientists may make use of the uncertainties you describe.
If you are aware of such standards for uncertainty applied in other fields, feel free to copy/paste or link here.
Types of Uncertainty
The discussion was started in the Discussion page for marine sediments
| Name | Definition | Notes |
|---|---|---|
| Analytical Uncertainty | Based on repeat measurements of a standard, 1SD | Or the nominal precision of the instrument (for instance error on weight measurements for a microbalance . |
| Reproducibility | Based on repeat measurements of a sample | "Most proxy climate data uncertainties are best quantified through sample replication. This has rarely been rigorously accomplished in the past, outside of dendroclimatology and even in this field, there was a call for greater numbers of samples." [1] |
For the uncertainty based on reproducibility, should the number of repeat measurements used to determined the reproducibility be:
