Global Waveform Shape Analysis for the Detection and Monitoring of Ephemeral Surface Water

The past 15 years of satellite radar altimeter missions have resulted in the creation of a huge database of echoes collected over the earth’s land surfaces. These echoes contain information on the changing distribution of surface water in the form of snow, ice and liquid water. Key to the interpretation of this information is the detailed analysis of echo shapes. This paper presents results from the global analysis of multi-mission altimeter waveform data, illustrating the unique information content of these echoes, and demonstrating the potential for detection and monitoring of the changing patterns of ephemeral surface water using this approach.
