Description: This is a subset of the total Sentinel-2 Copernicus collection for the Midwest Tornadoes in March 2025. Other subsets from various affected National Weather Service (NWS) Weather Forecast Offices (WFOs) can be found at the following links.

The RGB is created using the red, green, and blue channels of the respective instrument.The dynamically generated Normalized Difference Vegetation Index (NDVI) layer is an index for quantifying green vegetation. It reflects the state of vegetation health based on how vegetation reflects light at certain wavelengths.Suggested Use:The True Color RGB provides a product of how the surface would look to the naked eye from space. The True Color RGB is produced using the 3 visible wavelength bands (red, green, and blue) from the respective sensor. Some minor atmospheric corrections have occurred.For NDVI, dark green colors are areas with a lot of green leaf growth which indicates the presence of chlorophyll. Chlorophyll reflects more infrared light and less visible light. Areas with some green leaf growth are in light greens, and areas with little to no vegetation growth are even lighter greens.Satellite/Sensor:MultiSpectral Instrument (MSI) on European Space Agency's (ESA) Copernicus Sentinel-2A/2B satellitesResolution:10 metersCredits:NASA/MSFC, USGS, ESA CopernicusEsri REST Endpoint:See URL section on right side of pageWMS Endpoint:https://maps.disasters.nasa.gov/ags03/services/midwest_tornadoes_202503/sentinel2_meg/MapServer/WMSServerData Download:https://maps.disasters.nasa.gov/download/gis_products/event_specific/2025/midwest_tornadoes_202503/sentinel-2/

The RGB is created using the red, green, and blue channels of the respective instrument.The Experimental Binary NDVI change product is highlighting areas that experienced change (of any kind) since the pre-event Copernicus Sentinel-2 pass used in the analysis. The product is further filtered to reduce noise and focus the identification on the more pronounced areas of change in an effort to identify areas that may have experienced damage during Hurricane Helene's passage and associated water and wind impacts.Suggested Use:The True Color RGB provides a product of how the surface would look to the naked eye from space. The True Color RGB is produced using the 3 visible wavelength bands (red, green, and blue) from the respective sensor. Some minor atmospheric corrections have occurred.This binary mask layer is designed to overlaid with post event imagery (pre if it is available as well). The True color imagery or the Color IR RGB should be used to orient the user to areas that match the type of change being investigated. Color IR RGB uses infrared channels to isolate areas of high vegetation (and greenness) in red from areas that are not, such as cities, rivers, which will appear in shades of green/teal. Clouds are white while cloud shadows tend to be black (or close to it)Satellite/Sensor:MultiSpectral Instrument (MSI) on European Space Agency's (ESA) Copernicus Sentinel-2A/2B satellitesResolution:10 metersCredits:NASA/MSFC, USGS, ESA CopernicusEsri REST Endpoint:See URL section on right side of pageWMS Endpoint:https://maps.disasters.nasa.gov/ags03/services/ohio_flooding_202502/sentinel2/MapServer/WMSServer'Data Download:https://maps.disasters.nasa.gov/download/gis_products/event_specific/2025/ohio_valley_flood_202502/sentinel2/
