Operational Analysis of Winter Cover Crop Environmental Performance throughout the State of Maryland

Winter cover crops increase the sustainability of agricultural lands and the health of surrounding watersheds through erosion control and nutrient retention. The Maryland Department of Agriculture (MDA) incentivizes the planting of winter cover crops in the Chesapeake Bay area via a cost-sharing program that offers...

A composite showing the difference in NDVI between the Summer and Winter of 2019 to capture phenology along the Colorado River in the Grand Canyon. Indices derived from Landsat 8 OLI SR, June 19 and Dec 12. Darker shades of brown indicate a greater difference in NDVI while darker shades of green indicate a lower difference. Pairing on-the-ground phenology observations with remotely sensed data can increase partners' monitoring capacity of native and non-native riparian species.  Keywords: Phenology, NDVI, Landsat

Native plant species in the Colorado River Basin are currently threatened by non-native species that are changing resource competition dynamics. Monitoring native species is essential for understanding changes in plant health throughout the year as well as how species’ distributions...

Predicting Grunion Migration Patterns and Spawning Areas in Response to Changes in California's Oceans

The California grunion (Leuresthes tenuis) is a species of fish endemic to the California coastline that plays an important role in the marine food chain as a consumer of zooplankton and a food source for larger marine creatures. Grunion spawning events, commonly referred to as...

NDVI-processed imagery using Landsat 8 OLI data. Image is displaying Victoria Falls and its surrounding land area in Zimbabwe during the 2019 wet season (November – April). Darker shades of purple indicate healthier vegetation and brighter shades of yellow indicate less healthy vegetation. The yellow band in the right center of the image indicates agricultural plots where elephant crop raiding events have been recorded.   Keywords: NDVI, Zimbabwe, Victoria Falls, Human-Elephant Conflict, Climate, Vegetation, Elephant Habitat, Agriculture

Human-wildlife conflict is increasingly more common due to human population growth, habitat fragmentation, and changing climatic conditions. This conflict is particularly evident in the Kavango-Zambezi area, where over three million people share the landscape with an abundant megafauna population. As...

Land use land cover classified image using Landsat 8 OLI imagery. The Landsat 8 imagery was collected between March and July of 2020. The alluvial fan of the Okavango Delta in Botswana is pictured. The cyan blue represents wetland habitats and dark blue is permanent water. Shades of green indicate woodlands and grasslands. The orange patches are agricultural areas that are prone to human-elephant conflict events and are the focus of this project’s research.  Keywords: Land Cover Classification, Kavango-Zambezi TFCA, Human Elephant Conflict, Okavango Delta, Google Earth Engine

In the Kavango-Zambezi area of southern Africa, three million people live within areas frequently traveled by free-ranging elephants. As the region continues to develop rapidly, urban and agricultural settlements further encroach upon the land that these elephants use. As elephants come...

Imagery from Sentinel-5P Offline Nitrogen Dioxide dataset over the Puget Sound in Washington State. Data for hillshade sourced from the Shuttle Radar Topography Mission. Aerosol layer has been classified according to the EPA's Air Quality system, with green indicating healthy conditions, to maroon, which indicates hazardous air quality. A poor air quality event is displayed from August 14, 2018, when an inversion was compounded with wildfire particulate coming from British Columbia and western Washington.  Keywords: Public health, MODIS, MAIAC, Sentinel-5P TROPOMI, Google Earth Engine, CALIPSO CALIOP

In the Puget Sound region of Washington, high levels of air pollutants put residents’ health at risk by increasing their likelihood of developing critical respiratory conditions. This project used remotely-sensed data to investigate aerosol optical depth (AOD) from NASA satellite...

Mean land surface temperature derived from 2016-2020 Landsat 8 OLI/TIRS imagery in central Sacramento, located in the California central valley, is displayed. Orange coloring is used to indicate which areas experience the urban heat island effect, with darker colors indicating a higher magnitude of urban heat. The darkest orange colors indicate areas where the city should invest more in urban cooling infrastructure.   Keywords: Urban heat island, Landsat, California, Central Valley, Sacramento, Nicole Keller, Elspeth Gates, Anjelica Petsch, Karina Alvarez

The combined effects of increasing urbanization and climate change have exacerbated the urban heat island (UHI) effect and heat-related risks for city dwellers. Vulnerability to heat-related illnesses is further compounded by risk factors such as demographics, socioeconomic status, and pre-existing...

Nighttime Land Surface Temperature(LST) Anomaly image processed using Aqua-MODIS LST and Emissivity data. The image displays temperature differences from mean nighttime temperature for Eastern Massachusetts for June, July and August of 2019 combined. Brighter shades of yellow represent positive temperature anomalies, or 'hot spots,’ and darker shades of purple represent negative temperature anomalies or 'cool spots.’ These products will help city planners understand how heat varies across the landscape.   Keywords: urban heat island, nighttime land surface temperature, climate preparedness, remote sensing, Cambridge, Massachusetts​

The urban heat island (UHI) effect occurs when urban areas have temperatures that are warmer on average than the surrounding suburban and rural regions. Low albedo surfaces traditionally found in urban landscapes, such as dark asphalt and rooftops, absorb solar irradiance...

Quantifying Changes in Urban Tree Canopy Cover and Land Surface Temperature to Understand Their Impacts on Neighborhoods throughout Richmond, California

With the aim of improving air quality and mitigating increases in land surface temperature (LST), the city of Richmond, California, and partnering organizations have planted 35,000 trees over the past decade. Groundwork Richmond (GR) a local partner, has approximately 22,000 tree planting opportunities to further...

Imagery displaying Normalized Difference Vegetation Index (NDVI) values calculated from 2018 Landsat 8 OLI data and cropped to a subset of Eastern Maryland bordering the Chesapeake Bay. Black areas correspond to regions of low vegetation density, red to medium vegetation density, and yellow to high vegetation density. Within agricultural regions, low NDVI may indicate areas in which local stakeholders could commit additional resources. Water has been replaced with a stylized cover crop image (green).

Cover crops enrich soils, limit erosion, and reduce nutrient runoff from agricultural land. To promote their usage, the Maryland Department of Agriculture (MDA) subsidizes farmers who plant winter cover crops. In order to maximize environmental benefits, cover crops must be...
