![Models of two invasive plant species in the Northeast US. Established invasive Microstegium vimineum (top) modeled with high-resolution, US-specific data, and new arrival Oplismenus undulatifolius (bottom) modeled with widely accessible, low-resolution data. Probability of species presence ranges from low (blue) to high (pink). The Appalachian Trail (white), an important vector of non-native plant invasion, crosses this region northwest of Washington, DC.

![Satellite image showing Venus flytrap habitat in coastal North Carolina. NDVI, derived from Landsat 8 OLI/TIRS sensors from April – July 2021, measures health and density of vegetation. Orange and red represent low and high burn severity, respectively, whereas pink and green represent low and high NDVI. The DEVELOP team used NDVI and fire severity data as input for Venus flytrap habitat suitability models, which botanists can use to support the conservation of Venus flytrap.](/sites/default/files/styles/lis/public/2022-03/2021Fall_GA_CCPEco_WebsiteImage.png.webp?itok=PUDex4jB)

![Temperature anomalies for 2020 were derived from Terra MODIS Daily Land Surface Temperature (LST) data and compared to the 20-year average (2000 – 2020) in Maine. Shown is an enlarged subset of Maine. Stream vectors are represented in light blue. Blue pixels represent decreases in LST (cooler temperatures), green pixels represent areas of neutral change (average temperatures), while red and yellow pixels represent increases in LST (the highest temperatures).](/sites/default/files/styles/lis/public/2022-03/2021Fall_GSFC_MaineEco_WebsiteImage.jpg.webp?itok=9Ej487B3)

Yellow, red and violet areas represent high, medium, and low habitat suitability respectively. Yellow area is prime surveying location for mustelid species.](/sites/default/files/styles/lis/public/2022-03/2021Fall_GSFC_WesternMontanaEcoII_WebsiteImage.png.webp?itok=lR_GDQpk)

![Potential for land cover to change from trees to grass, forb, and herb between 1987 and 2020 in the Teton Mountain Range. Image created from LCMS land cover data which are derived from Landsat 4, 5, 7, and 8 imagery (1987 - 2020). High transition potential is depicted in yellow and low transition potential is indigo. Transition potentials help to forecast land cover and inform land managers on the locations of suitable bighorn sheep habitat.](/sites/default/files/styles/lis/public/2022-03/2021Fall_ID_GrandTetonEco_WebsiteImage.png.webp?itok=q05PkvLT)

![The difference in Aerosol Optical Depth (AOD) between ozone spike days in summer 2018 and 2020 in Seiling, Oklahoma. AOD measures particles distributed within a column of air and can help predict tropospheric ozone spikes and inform regulatory organizations. Data derived from Terra and Aqua MODIS with 2020 Landsat 8 imagery as a base map. Yellow represents the greatest difference in AOD and purple represents the least difference, with green in the middle.

![Oversampled nitrogen dioxide (NO2) atmospheric column data from select months (May – September) in 2019 derived from the OMI sensor aboard the NASA Aura satellite. The darker purple colors reflect lower concentrations of NO2 in our study region, but as the color scale moves towards brighter yellow it represents high concentrations of NO2. Assessing the NO2 gas distribution, in addition to other gases, can aid project partners in identifying hotspots of emissions.](/sites/default/files/styles/lis/public/2022-03/2021Fall_LaRC_SoutheastMichiganNorthernOhioHealthandAirQuality_WebsiteImage.png.webp?itok=-X50Y6mw)
