Measuring California Air Quality through the Use of Earth Observations to Assess the Socioeconomic Distribution of Air Pollution and Effects of Policy Initiatives

Thirty-five million California residents live in counties where they are more susceptible to contracting an air quality-related health ailment. Particulate matter less than 2.5 µm in size (PM2.5) is an important metric of air quality and can cause significant health problems. Despite California's policies targeted...

NDVI was processed from fall of 2019 using Landsat 8 Top Of Atmosphere imagery. Annual average land surface temperature (LST) was retrieved from MODIS for 2019. The area around Gelephu in the Southern part of Bhutan is displayed. Light blue represents low LST, red represents high LST, and medium range of LST is indicated by light purple. Healthier vegetation is indicated by green. Examining these variables can help partners in planning suitable elephant ecological corridors.   Keywords: Bhutan, Gelephu, Landsat 8 TOA, MODIS, NDVI, LST​

Asian elephants (Elephas maximus) are a flagship species essential for the functioning of forest ecosystems, and they also have cultural significance in Bhutan. Elephants receive the highest legal protection as listed under Schedule I of the Bhutan Forests...

Environmental contaminants are becoming increasingly prevalent in riverine ecosystems. The status of contaminants in western Montana’s relatively pristine river systems is largely unknown. Monitoring for heavy metals, brominated flame-retardants (BFRs), and pharmaceuticals is important due to their negative effects on ecosystems. Exposure to these contaminants can have significant endocrine, neurological, and reproductive effects. Contaminants easily travel up...

The relative saturation of Kansas root zone soil moisture on June 15, 2018, calculated using data from the Soil Moisture Active Passive (SMAP) L-band Radiometer. The maximum and minimum storage capacity were gathered by analyzing SMAP data from March 2015 to present. This image visualizes the agricultural drought that was taking place in central Kansas during the summer of 2018, with all of the values in brown representing less than 25% relative saturation.

Kansas is a leading state in agricultural production, however, during recent droughts, farmers experienced decreased yields that negatively impacted the state and national economies. The exponential decay of soil moisture content is a major consequence of drought, stymieing plant growth...

Difference Normalized Burn Ratio (dNBR) imagery showing the change in NBR from 2013 to 2019. Imagery was derived processed Landsat 7 ETM+ and Landsat 8 OLI data for the Silver Fire in the Gila National Forest. High dNBR represents healthy vegetation, shown in green. Low dNBR represents unhealthy, shown in gray. dNBR values indicate how the landscape has recovered postfire, which aids Burned Area Emergency Response (BAER) teams in future treatment applications.   Keywords: Normalized Burn Ratio, Gila National Forest, New Mexico, Silver fire, wildfire, Landsat, BAER

In recent years, wildfires in New Mexico’s Gila National Forest have become increasingly common and more severe. Wildfires can have powerful impacts on hydrology and soil stability, including erosion, flooding, and debris-flows that threaten lives and infrastructure downstream. Vegetation restoration...

Monitoring Air Quality in Shenandoah National Park to Address National Park Service Initiatives Using NASA Earth Observations

Air quality is considered one of Shenandoah National Park's most fundamental resources. The park's ecological health and visitor attendance is dependent on maintaining high air quality standards. This project utilized the NASA's Aerosol Optical Depth (AOD), aerosol extinction profile, and Tropospheric Ozone Residual (TOR) datasets...

Monitoring and Forecasting Precipitation Patterns and Erosion Potential to Enhance Archaeological Preservation and Decision Making

Increasing yearly monsoonal precipitation severity in Navajo National Monument (NAVA) is exacerbating erosion and arroyo cutting, affecting culturally significant archaeological sites in the area. In order to better understand and mitigate erosional processes, land managers at the park would benefit from comprehensive rainfall data and...

Monitoring and Predicting the Spread of the Roseau Cane Die-offs Connected to the Invasive Mealy Bug (Nipponaclerda biwakoensis) and Other Contributing Factors in the Mississippi River Delta Using NASA Earth Observations

The Roseau cane mealy bug (Nipponaclerda biwakoensis) is an invasive scale insect discovered in the United States during the 2016-2017 die-offs of Roseau cane (Phragmites australis) in the Mississippi River Delta, Plaquemines Parish, LA. Roseau cane stabilize sediment, protect against wave-action and storm surge, and...

Monitoring Bighorn Sheep Habitat by Assessing Vegetation, Topography, and Soil Moisture

Bighorn sheep are a charismatic desert species that have enormous ecological and cultural significance to the Mojave Desert region in California. After overcoming large population losses in the late 1900s, further habitat degradation and fragmentation has continued to affect the livelihood of remaining bighorn sheep...
