The fugitive emissions of volatile organic compounds (VOCs) from industrial processes are currently managed through in-person leak detection and repair (LDAR) efforts that are costly and occur periodically. These emissions are not rigorously accounted for in current emissions inv...

The content covers the validation of the NASA TEMPO mission with direct sun and multi-axis retrievals of NO2 and formaldehyde trace gas vertical column products from the Pandonia Global Network. The slides present nuances in the strengths and weakness of Pandonia Global Network d...

Above ground storage tanks/terminals provide an essential link in the transportation of fuel between national infrastructure (e.g., pipelines) and local distribution points (e.g., gas stations). Volatile components of refined gasoline/fuels (including ozone precursors and air tox...

Accurate fire emissions inventories are crucial to predict the impacts of wildland fires on air quality and atmospheric composition. Two traditional approaches are widely used to calculate fire emissions: a satellite-based top-down approach and a fuels-based bottom-up approach. H...

Battelle and EPA evaluated the effectiveness of UAV platforms to perform volumetric measurements of various types of debris (e.g., biomass such as fallen vegetation, stacks of building material, and other debris) using  lidar and structure from motion (SfM) photogrammetry. T...

General overview of the Cyanobacteria Assessment Network (www.epa.gov/cyanoproject) current technology, software, and data. A future look of using Sentinel-2 higher resolution imagery and forecasting will also be provided.

This product evaluates various methods to determine the presence of leaded materials within premise plumbing, particularly lead service lines, but considers all lead sources. This can be done in numerous ways from innovative tap sampling methods, novel sensors and visual inspecti...

CyAN is a multi-agency project to develop an early warning indicator system to detect algal blooms in U.S. freshwater systems. This research supports federal, state, tribal, and local partners in their monitoring efforts to assess water quality to protect aquatic and human health...

Cyanobacterial harmful algal blooms (cyanoHABs) are detrimental not only to human and ecosystem health, but also to local economies that rely on surface water for consumption, tourism, and recreation. Previous work has been done to predict cyanoHABs in Florida at the lake and sta...

Cyanobacterial harmful algal blooms pose environmental, economic, and human health concerns across waters of the United States.  However, monitoring changes in cyanobacteria at broad spatial and temporal scales remains difficult and many times with sporadic coverage. The Cya...

Cyanobacterial harmful algal blooms are a global problem with a need for synoptic monitoring capability.  The project objective is a Sentinel-2 (S-2) chlorophyll demonstration monitoring product for Florida, Ohio, and Oregon. This is an annual project report to the USACE Har...

Mangrove forests in developed and developing countries are experiencing substantial transformations driven by natural and anthropogenic factors. This study focuses on the conterminous United States, including Florida, Texas, and Louisiana, where coastal development, urbanization,...

Review article for an special issue in the journal of remote sensing on remote sensing in mangrove. The article highlights frontiers in remote sensing assesment and monitoring at a global scale and summarizes paper published in the special issue.

Economists typically estimate the average treatment effect on the treated (ATT) when evaluating government programs. The economic interpretation of the ATT can be ambiguous when program outcomes are measured in purely physical terms, as they often are in evaluations of ...

Mangrove forests are distributed in the tropical and subtropical regions of the world largely con-fined within ± 10 degrees latitude. The forests provide important ecosystem goods and services to nature and society. In recent years, the carbon sequestration potential and p...

Under a warmer future climate, thermal refuges could facilitate the persistence of species relying on cold-water habitat. Often these refuges are small and easily missed or smoothed out by averaging in models. Thermal infrared (TIR) imagery can provide empirical water surface tem...

The National Land Cover Database (NLCD), a product suite produced through the MultiResolution Land Characteristics (MRLC) consortium, is an operational land cover monitoring program.  Starting from a base year of 2001, NLCD releases a land cover database every 2-3-years.&nbs...

The National Land Cover Database (NLCD) is an operational land cover monitoring program providing updated land cover and related information for the United States at five-year intervals. NLCD 2016 extends temporal coverage to 15 years (2001 – 2016). Accuracy assessment of N...

Human and ecological health have been threatened by the increase of cyanobacteria harmful algal blooms (cyanoHABs) in freshwater systems. Successful mitigation of this risk requires understanding the factors driving cyanoHABs at a broad scale. To inform management priorities and ...

This study examines the current literature on aerial photography, remote sensing, and ground-based sensor use for estimating waste and debris volume. While there is a growing body of research in this area, the application of Unmanned Aerial Systems (UAS) remote sensing in post-di...

This overview is designed for a general audience without expertise in satellite remote sensing and forecasting. It is meant to highlight how the Cyanobacteria Assessment Network, CyAN , might provide useful real-time data, software, training, annual summary metrics, and 1-week fo...

Frequent remotely sensed observations of surface waters at fine spatial scales will provide critical data to support the management of aquatic habitat, including projecting the impacts of climate change on freshwater ecosystems. We developed surface inundation algorithms for Sent...

This overview is designed for a general audience without expertise in satellite remote sensing and forecasting. It is meant to highlight how the Cyanobacteria Assessment Network, CyAN , might provide useful real-time data, software, training, annual summary metrics, and 1-week fo...

Cyanobacterial harmful algal blooms (HABs) can produce toxins that impair freshwater ecosystems used for drinking water, recreation, and habitat for aquatic biota. With HABs increasing in extent and intensity globally, water managers need information about how to prioritize lake ...

Mangrove forests in both developed and developing countries are experiencing substantial transformations driven by natural and anthropogenic factors. This study focuses on the conterminous United States, including Florida, Texas, and Louisiana, where coastal development, urbaniza...
