![NDVI-processed imagery taken by Landsat 9 OLI-2 in May 2022 of Bryce Canyon National Park and nearby urban area. Healthy vegetation are visualized as bright yellow, while stressed plants, bare earth, and urban areas approach dark red. The continuity of the Landsat program described vegetation response to pervasive drought conditions in Bryce Canyon which the National Park Service can use to when making conservation decisions.](/sites/default/files/styles/lis/public/2023-02/2022Fall_GSFC_BryceCanyonWaterResources_WebsiteImage.png.webp?itok=mswmR89-)

![We created an averaged seasonal Evaporative Stress Index (ESI) composite for fall 2020 in the west Tennessee region utilizing NASA’s ECOSTRESS sensor onboard the International Space Station. The ESI reveals areas where vegetation is stressed due to lack of water. Dark blue regions represent areas where vegetation is thriving, compared to the yellow areas, where vegetation is experiencing some water stress.](/sites/default/files/styles/lis/public/2023-02/2022Fall_JPL_WesternTNWater_WebsiteImage.jpg.webp?itok=BhQQZWBf)

![NDTI-processed imagery from Landsat 8 OLI data. This image from October 2021 depicts the turbidity of Keweenaw Bay, western Michigan coastline of Lake Superior. Light blue-colored water indicates greater turbidity while darker blue water is less turbid. Turbid waters indicate coastal erosion and re-distribution of legacy copper mining waste colloquially referred to as "stamp sands". Stamp sands contaminate wetlands and threaten traditional food sources for Indigenous communities along the bay.](/sites/default/files/styles/lis/public/2023-02/2022Fall_LaRC_KeweenawBayWater_WebsiteImage.jpg.webp?itok=J-ICa-DH)

![NDBI-processed imagery from a June 2022 Landsat 9 OLI-2 image. This composite image shows the cities of Warren (top left) and Youngstown (bottom right). The areas in white and brown represent the built environment. While areas in green represent land that is not as built-up, such as forest. Built-up areas can indicate where surface run off could occur, resulting in pluvial flooding.](/sites/default/files/styles/lis/public/2023-02/2022Fall_LaRC_YoungstownWarrenDisasters_WebsiteImage.jpg.webp?itok=EkdUM8uk)

![Aph(433)-processed imagery from merged Aqua MODIS and Sentinel-3 data. This image of the Gulf of Maine was taken on September 12, 2016 during one of the most severe harmful algal bloom events. Using in-situ data, it was determined that Pseudo-nitzschia was a dominant genus of algae present at the time of the bloom. Shades of bright green indicate peak absorption by phytoplankton and aph(433) is corrected for false positive absorption indications.](/sites/default/files/styles/lis/public/2023-02/2022Fall_MA_GulfofMaineWater_WebsiteImage.jpg.webp?itok=CezSF3AF)

![Stormwater retention across Wyandotte County, Kansas. NASA GPM IMERG data for September 2020 – August 2021 and NLCD 2019 Land Cover data were used as model inputs for the InVEST Stormwater Retention Model. One model output included a stormwater retention ratio layer where darker purple values indicate poor stormwater retention and increased flood risk. Areas of poor stormwater retention can then be identified as priority regions for Green Infrastructure initiatives in Wyandotte County.](/sites/default/files/styles/lis/public/2023-02/2022Fall_MA_KansasCityDisastersII_WebsiteImage.png.webp?itok=sqRBpysQ)

![Normalized burn ratio calculated from Landsat 8 imagery both preceding and following the Bootleg Wildfire in the Beatty, Oregon area. The fire burned from July 6th to August 15th during the Summer of 2021 and its footprint shows varying levels of burn severity. Dark purple areas indicate highest severity, shades of red and orange indicate moderate severity, and yellow areas indicate low burn severity. Black areas depict unburned areas.](/sites/default/files/styles/lis/public/2023-02/2022Fall_NC_Gatlinburg%26BeattyWildfires_WebsiteImage.jpeg.webp?itok=_JPQMuhI)

![Landsat 8 OLI data processed into the median NDVI for 2016-2021 with an overlay showing deforestation that occurred during this time period in the Talladega National Forest. The deforestation layer is derived from Global Forest Watch's forest cover data, which uses the Landsat series, and was calculated as the difference between forested areas in 2016 and forested areas in 2021. Shades of green indicate the density of forest, while red areas indicate areas deforested in 2021.](/sites/default/files/styles/lis/public/2023-02/2022Fall_PUP_SoutheastUSClimate_WebsiteImage.jpeg.webp?itok=9thA-LxI)
