Evaluating the Potential of CYGNSS Wind Data to Assess Tropical Storm Impacts on Energy Infrastructure in the Gulf of México

In recent years, the Gulf of México (GoM) has gained national attention for its significant contributions to the country’s overall oil supply – the area today accounts for 17% of all US oil production. The production and availability of such oil resources is threatened when...

Focused on of the southern half of Mobile County, Alabama, this is an NDVI-processed image overlaid by a land surface temperature (LST) layer obtained from 2019 Landsat 8 OLI/TIRS data. The darker red in the overlay indicate higher LST and lighter yellow shades indicate lower LST. The lighter green tones in the base image represent less healthy vegetation and darker tones represent healthier vegetation. Maps like this help partners identify and mitigate the effects of urban heat islands.

This project utilized satellite Earth observations to assess locations in Mobile County, Alabama, that are vulnerable to the urban heat island effect (UHI) and flood impacts. Our partner, Groundwork Mobile County (GWMC), and other local entities need information on UHIs...

Above is a supervised land cover classification image using a mosaic of July 12, 19, and 28, 2018 Landsat 8 OLI data of Cumberland County, Maine. The shores of Yarmouth, Harpswell, and Chebeague Island are displayed. Scaled urbanization is shown with lighter blues indicating the most vegetated areas and darker blues indicating the most impervious urban areas. Navy blue represents water. Identifying the land cover type allows for better understanding of tick encounter risk.

Tick-borne diseases are a public health issue in southern Maine, and recent estimates completed by the State of Maine suggest that as little as 1 in 10 cases of Lyme disease are actually reported. There are three tick-borne diseases known...

Split-season composite from May (leaf-on) and November (leaf-off) 2018 in the Allegheny Mountains of West Virginia. This Landsat 8 OLI imagery displays a color combination of SWIR_1 (leaf-on), SWIR_1 (leaf-off), and NIR (leaf-on). Urban areas are shown in pink, impervious surfaces in periwinkle, conifer forests in dark green, and exposed soil in orange. This stack, and others like it, are used for determining land cover classifications and collecting training data for forest restoration efforts.

the Monongahela National Forest (MNF), situated in the Allegheny Highlands of West Virginia, extensive logging and mining practices have significantly altered the structure and composition of flora and fauna over the past two centuries. Of particular concern to MNF land...

Generating Hemispherical Visualizations of Artificial Sky Brightness Using Updated Sky Glow Estimation Tools on Suomi NPP-VIIRS Data

The expansion of the global population in conjunction with rapid industrialization has caused an increase in artificial light pollution, also known as artificial sky glow. Anthropogenic light pollution disturbs the world's ecosystems by interfering with the interconnected life of flora and fauna, degrading night sky...

NASA’s Gravity Recovery and Climate Experiment (GRACE) and Sentinel-1 C-band Synthetic Aperture Radar (SAR) can be used to evaluate groundwater depletion and land subsidence. Groundwater storage change, calculated from GRACE, and land surface subsidence, calculated from Sentinel-1 C-SAR, from March 2015 to August 2019 are shown in the California Central Valley. Redder shades indicate greater groundwater storage loss detected by GRACE. Sentinel-1 data shown in blue, illustrates greater land subsidence in darker blue.   Keywords: GRACE, InSAR, land subsidence, groundwater storage, California, Central Valley, Kathleen Lange, James Kitchens, Vanessa Valenti, Elizabeth Perez

California’s Central Valley is one of the most productive agricultural regions in the United States, producing a fourth of the nation’s food supply. The water demand in this region is heavily dependent on groundwater resources, resulting in over pumping of...

Landsat 8 Operational Land Imager multi-year composite 2017 to 2019. The false color band combination 4, 3, 2 shows land cover distinctions of Southern Panay Island in the Philippines. Primary Forest is represented by the darker red shade along the center. Lighter shades of red indicate Secondary Forest cover. Distinct shades of brighter blue characterize urban areas of the island. Displaying differences in land cover can assist with identifying favorable habitats for endemic species.  Keywords: Visayan Islands Ecological Forecasting

The islands of Negros and Panay in the Philippines contain the last existing habitat for the critically endangered Visayan spotted deer (Rusa alfredi) and Visayan warty pig (Sus cebifrons). NASA DEVELOP partnered with the Arizona Center for Nature Conservation –...

A 30-meter resolution map from a 4/26/2019 Landsat 8 OLI image with a tasseled cap brightness transformation overlaid on a solar insolation map derived from a 9/23/2014 DEM created with the SRTM C-Band. Lawrence, Kansas, is featured here. Bright yellow signifies areas with high surface reflectance, indicating bare soil and rooftop areas ideal for solar panels. Darker purple signifies areas of low surface reflectance, indicating forest and wetland locations not ideal for solar panels.

The City of Lawrence and Douglas County, Kansas, are working to reduce greenhouse gas emissions and achieve 100 percent renewable energy. The NASA DEVELOP team used Shuttle Radar Topography Mission (SRTM) and LiDAR elevation data along with Landsat 8 Operational...

The Enhanced Vegetation Index (EVI) quantifies vegetation greenness over a dense canopy section of Southern Costa Rica using a Landsat 8 OLI composite from 11-01-2018 through 12-31-2019. The coral to pink hues indicate healthier vegetation, the orange to gray indicate less healthy vegetation. The black indicates the absence of vegetation and the river is rendered in aqua. This image illustrates the variability of vegetation health to allow stakeholders to identify areas of sparse vegetation.
