Caveats	Agricultural-related flooding: Some flooding water shown in the VIIRS flood maps may not be any hazardrelated flooding, but from agriculture-related activities such as rice paddy planting and aquaculture. ● Tides and Marsh lands: In some regions especially coastal areas, consistent flooding may be detected in the flood maps. These floods are mostly caused by the tides or occur over marsh lands, which do not pose any social impact. ● Water reference map: The current water reference map we use for global flood mapping is from global water bodies of ESA CCI and MODIS global water mask (MOD44W Version 006). It might not reflect the new reservoirs and other hydraulic projects built after 2015, which may take some normal water as flooding water. ● Solar Eclipses: For granules that are flagged as an “eclipse”, the flood product will not be produced.
