General Comment: Satellite requirements for Flood Forecasting. Horizontal threshold resolution changed to 50Km from 250km based on this paper because 250Km was very coarse. https://ntrs.nasa.gov/api/citations/20205000995/downloads/Manuscript_revision.doc.pdf Confidence: reasonable
Def: :Not firm, but based on a strong heritage of experiments with similar data
