Global Lake Observability from SWOT: Where and in What Quantity Are Lakes Observable by SWOT? [presentation]
Sheng, Y., Song, C., Lettenmaier, D.P., and Ke, L. (13-Dec-16). The SWOT mission's scientific requirements state that SWOT should provide a global inventory of terrestrial surface water bodies whose surface area exceeds 250x250 m2. However, our knowledge about locations and quantities of SWOT-observable lakes is rather limited. This research intends to produce a SWOT-observable lake map using our recently produced global lake database, SWOT orbits, and terrain layover effect simulation based on KaRIn's sensing geometry.

Model-based Adaptive Water-body Lake Mapping and Lake Modeling from SWOT/KaRIn
PI: Yongwei Sheng (17-Jun-17). This project seeks to contribute to lake mapping and lake product generation in the SWOT mission. We in Year 1 concentrated on modeling SWOT topographic layover distributions based on KaRIn's sensing geometry, and analyzing global lake observability from SWOT using our recently produced global high-resolution lake database, SWOT orbits, and terrain layover simulation. The major research objectives in Year 2 include (1) to finalize global lake observability results and study global reservoir observability; (2) to model uncertainty in SWOT lake mapping; (3) to investigate lake compositing methods in cycle-based lake product generation.
