Post-Event: May 8, 2024; May 15, 2024<\/span><\/p>

Pre-Event: April 6, 2024; April 21, 2024<\/span><\/p>

Summary:<\/span><\/p>

True Color: The True Color RGB composite provides a product of how the surface would look to the naked eye from space. The RGB is created using the red, green, and blue channels of the respective instrument.<\/span><\/p>

Color Infrared: The Color Infrared composite is created using the near-infrared, red, and green channels, allowing for the ability to see areas impacted from the fires. The near-infrared gives the ability to see through thin clouds. Healthy vegetation is shown as red, water is in blue.<\/span><\/p>

Suggested Use:<\/span><\/p>

True Color: 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.<\/span><\/p>

Color Infrared: depicts healthy vegetation as red, water as blue. Some minor atmospheric corrections have occurred.<\/span><\/p>
