Albedo derived from Landsat 8 & 9 OLI data throughout summer 2019 to 2023. White beige pixels signify effective solar radiation reflection (higher albedo), followed by peach, violet, and dark purple. This data is input for the InVEST Urban Cooling model, which calculates heat dissipation efficiency. Light-colored roofs and dense vegetation can increase albedo. Urban areas with lots of purple patches may be more vulnerable to heat, making them a priority for heat mitigation efforts.

Normalized Difference Water Index (NDWI) to visualize drainage networks around the Unalakleet River in Alaska, calculated from an August 2021 Landsat 8 OLI image. Yellow represents standing or flowing water and potential flood zones, while the dark blue represents drier, upland regions. Unalakleet's climate resilience planning prioritizes relocation to upland regions while avoiding areas that have experienced significant permafrost degradation.
