DA10 provides an estimate of the measurement uncertainty for each value in the water vapor profile. The uncertainty profile is based on 2-min water vapor profiles computed only for use in internal algorithms. The standard deviation of the 2-min data over the averaging time is computed and reported as the uncertainty. This is an estimate that describes the random uncertainties in the measurement.
The unit for uncertainty is gram of water vapor per kilogram of dry air (g kg-1). The uncertainty values are valid within the valid range of water vapor profiles.
