Normalized Difference Moisture Index (NDMI) processed 2021 Landsat 8 OLI imagery over land and Sentinel-2 MSI over ocean, ranging from yellow (low) to blue (high), for Hilo, Hawaii. Overlayed with four-day rainfall accumulation cells in blue acquired during Hurricane Lane (Aug 22-25, 2018) from CHIRPS Daily. NDMI monitors water content of leaves and is useful for classifying land cover. Impervious surfaces and areas that have received excessive historical rainfall are susceptible to future flood events.

NDTI-processed imagery using 1999-2021 Landsat 7 ETM+ and Landsat 8 OLI data, processed with SHARQ and ORCAA. Displayed is an East-oriented view of St. Joseph Peninsula off the Florida panhandle. Brighter shades of pink indicate greater change in turbidity levels post-Hurricane Michael, while shades of purple represent lower turbidity change. This increase in sediment post-hurricane indicates disturbed aquatic vegetation due to extreme storm events.
