Uncertainties in Ensembles of Regional Re-analyses
FIDUCEO Vocabulary
The GUM defines uncertainty as:
A parameter, associated with the result of a measurement, that characterises the dispersion of the values that could reasonably be attributed to the measurand.Uncertainty is a measure of the spread of the distribution of possible values.
A record of satellite observations of a geophysical quantity (such as sea surface temperature) in which estimates of total uncertainty (or error covariance) and/or dominant components of uncertainty (or error covariance) are provided or characterised at pixel-level (and potentially larger) scales. The CDR should be provided with all relevant auxiliary information for the data to be meaningful, including, e.g. time of acquisition, longitude and latitude, solar and viewing angles.
A record of calibrated, geolocated, directly measured satellite observations in geophysical units (such as radiance) in which estimates of total uncertainty (or error covariance) and/or dominant components of uncertainty (or error covariance) are provided or characterised at pixel-level (and potentially larger) scales. The FCDR should be provided with all relevant auxiliary information for the data to be meaningful, including, e.g. time of acquisition, longitude and latitude, solar and viewing angles, sensor spectral response.
