When the hypolimnion becomes anoxic and phosphorus releases from sediment, vertical profiling detects it before nutrients reach the surface and fuel algae growth. Remote Sensing from Satellite and Aerial Platforms: Multispectral satellite imagery estimates chlorophyll-a and maps algae distribution across thousands of hectares. Remote ...
Key Advantages of Hyperspectral Imaging HSI offers remote, non-destructive sensing; identification of invisible substances; high-precision real-time analysis; and easy integration into existing production lines. ...
The introduction of EPA OOOOb for new, modified, and reconstructed sources and OOOOc for existing sources represents a 400% increase in the regulated infrastructure and data collection burden.The “Super Emitter” Response Program SERPThe EPA has authorized certified third parties to identify large methane releases using satellite data, aerial flyovers, and remote ...

Introduction When people talk about water quality, they often focus on clarity or colour, but lake nutrients quietly shape almost everything that happens below the surface. A modest increase in nutrient loading can be the difference between a clear, oxygen-rich reservoir and one that drifts into chronic eutrophication with recurring algal blooms. For drinking water managers, understanding lake ...
Ozone serves as a protective layer in the upper atmosphere, absorbing harmful ultraviolet rays and helping sustain life on Earth. But at ground level, ozone transforms into a pollutant that can damage ecosystems, deteriorate infrastructure, and harm human health. This “ambient ozone” is a byproduct of chemical reactions between pollutants, such as nitrogen oxides (NO?) and volatile ...
Introduction Carbon dioxide (CO2) emissions are a significant contributor to global climate change, and understanding how to measure them accurately is crucial for addressing their impact. Whether from natural processes or human activities, monitoring CO2 emissions is necessary to mitigate their effect on our environment. This article will explore various methods, tools, and techniques to ...
Lakes play a vital role in providing drinking water, recreational activities, and biodiversity conservation. However, growing environmental challenges, including harmful algal blooms (HABs), climate change, and increasing human pressures, demand innovative approaches in lake management. This article examines five critical areas where innovation is essential and offers evidence-based ...
When Water Science and Data Science Team Up Against Harmful Algae The Context: Climate change and increasing human activity near water points cause cyanobacterial efflorescence to rapidly multiply, leading to potentially harmful water contamination. The Challenge: Because cyanotoxins have been associated with various health problems in humans and animals, these events can have serious impacts ...
South America is currently facing a devastating crisis as wildfires consume millions of hectares, especially in the Amazon basin. Over 400,000 fires have been reported, leading to catastrophic ecological damage and threatening countless species. The intense drought conditions have exacerbated the situation, creating an environment ripe for rapid fire spread. Activists are raising alarms over the ...
OPERA-S5 (OPEn platform for the Retrieval of Aerosol and CO2 from S5) includes two main objectives: the development of Open-Source Community Full-Physics XCO2 Retrieval Algorithm for Sentinel 5, and the demonstration of the developed algorithm by investigating the uncertainty characterization of CO2 and CH4 retrievals in the context of the challenging CO2M requirements using the proxy combination ...
The capability of Sentinel-5p foraerosol monitoringis currently not used to its full potential. However, satellite observations in the spectral range from approximately 340 to 400 nm are known to have unique sensitivity to elevation and absorption of tropospheric aerosols. Traditionally, this sensitivity is used in many ozone monitoring instruments such as TOMS, GOME-1, SCIAMACHY, OMI and GOME-2 ...
Reflectance of the Earth surface is one of the major natural components affecting climate. Surface interaction with incoming solar radiation and the atmosphere has a substantial impact on the Earth’s energy budget. Moreover, the accurate description of the surface reflection is crucial for different atmospheric studies including aerosol and trace gases ...
The current project intends to use the heritage of the CAWA project as well as the recent advancements realized within the GRASP-Open software package to establish and extend the concept for generating synergy MERIS+AATSR ...
AIRSENSE’s main objective is to enhance the understanding of aerosol and aerosol-cloud interactions. This activity is part of Atmosphere Science Cluster of ESA’s EO Science for Society programme, an element of the ESA FutureEO programme, which aims at boosting Europe’s excellence in EO science and its ...
The 3DREAMS project presents the concept of a 3D radiative Digital Twin Earth (DTE) and how it can be used to understand the effects of surface heterogeneities on aerosol retrieval from multi-angular observations. A series of realistic scenes will be generated and used by the Eradiate radiative transfer (RT) model for the simulation of satellite observations. The impact of various types of ...
Atmospheric aerosol is one of the main drivers of climate changes. Importance of accurate global aerosol characterization for climate studies and air pollution monitoring is a well recognized problem (e.g., see IPCC AR5 by Boucher et al.2013). In addition to the traditional spectral Aerosol Optical Depth (AOD) such characterization should also include such extended aerosol information asaerosol ...
Water is our planet’s most precious resource, essential for sustaining life. Yet, our water bodies face unprecedented challenges from pollution, climate change, and human activities. World Water Monitoring Day, celebrated annually on September 18th, is a crucial reminder of the importance of protecting and preserving water resources for current and future generations. At LG Sonic, we ...
It was developed and maintained by the American Society for Photogrammetry and Remote Sensing (ASPRS) as a standardized format for lidar data exchange and interoperability. ...
A decade ago, Toledo faced an unprecedented crisis when a toxic algal bloom in Lake Erie rendered the city’s water supply undrinkable for nearly three days. This disaster, which cost Toledo an estimated $65 million, not only disrupted daily life but also eroded trust in the city’s water system. ...
As global agricultural practices address environmental and economic challenges, regenerative agriculture has stood out as a promising approach to creating more sustainable and robust farming systems. This farming method focuses on restoring soil health, enhancing biodiversity, and improving water cycles, ultimately leading to more sustainable food production.
