Complete Uncertainty Characterization of the DISCOVER Earth System Data Records, PI: Carl Mears
Focus of this work
The purpose of this project is to perform a detailed error analysis of all ocean products from microwave radiometers provided by the DISCOVER project. We will add uncertainty estmates to each and every measurement of surface wind speed, columnar atmospheric water vapor, columnar cloud liquid water, rain rate and sea surface temperature. This short-term uncertainty information will be reported as an additional product. In addition, we will estimate long term uncertainty for each product. Both uncertainty products will be provided to users via our web page upon completion.
The project is a collaboration between Remote Sensing Systems, Atmospheric and Environmental Research, University of Wisconsin, and State University of New York, Albany.
Progress to date:
The algorithm to calculate uncertainty for AMSR-E is complete. The presentatation below summarizes the method we developed:

As part of the effort to estimate the accuracy of our rain rate data, we performed a detailed comparison with other sources of rain rate data. This work is summarized in the poster below:
