  • Map Algal Blooms with Satellite Remote Sensing Technology

    The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae. Algal blooms can result in ecological, ...

  • Remote sensing of soil degradation: Introduction

    In the 21st century, mapping and monitoring the occurrence of soil degradation will be an important component of successful land management. Remote sensing, with its unique ability to measure across space and time, will be an increasingly indispensible tool for assessing degradation. However, much of the recent experience and progress in using remote sensing and other geospatial technologies to ...

  • The influence of the land surface on hydrometeorology and ecology: new advances from modeling and satellite remote sensing

    The importance of land surface processes has long been recognized in hydrometeorology and ecology for they play a key role in climate and weather modeling. However, their quantification has been challenging due to the complex nature of the land surface amongst other reasons. One of the difficult parts in the quantification is the effect of vegetation that are related to land surface processes ...

  • Surface fluxes and atmospheric stability obtained from a surface energy balance model with parameters estimated from satellite remote sensing

    Surface fluxes and atmospheric stability affect atmospheric dispersion through their impact on low-level turbulence, mixing layer height, and mesoscale circulation patterns. In the first part of this paper, a sensitivity study is performed to demonstrate the impact of the land surface on energy fluxes and atmospheric stability. In the second part, a methodology to estimate surface heat fluxes and ...

  • Remote sensing models using Landsat satellite data to monitor algal blooms in Lake Champlain

    Lake Champlain is significantly impaired by excess phosphorus loading, requiring frequent lake-wide monitoring for eutrophic conditions and algal blooms. Satellite remote sensing provides regular, synoptic coverage of algal production over large areas with better spatial and temporal resolution compared with in situ monitoring. This study developed two algal production models using Landsat ...

  • Coastline Change Detection Using Remote Sensing

    Coast is a unique environment in which atmosphere, hydrosphere and lithosphere contact each other. Coastline is one of the most important linear features on the earth’s surface, which display a dynamic nature. Coastal zone, and its environmental management requires the information about coastlines and their changes. This paper examines the current methods of coastline change detection using ...

  • Mangroves of Godavari – Analysis Through Remote Sensing Approach

    Abstract  The expansion of agriculture and aquaculture farms in the coastal areas has led to conversion of mangroves in the recent past. The extent of mangroves has also changed due to the erosion of mangroves along the coast and accretion near river mouths, leading to the formation of new mangrove areas. This study has been undertaken in the mangroves of the Godavari estuary, Andhra ...


  • Managing the Earth from Space: Satellite and sensing technology in water management

    Approximately 200 miles above the Earth’s surface, two satellites circle the planet, always between 106 and 193 miles apart. But while these twins—called Gravity Recovery and Climate Experiment (GRACE)—live in space, they’re providing invaluable assistance in managing natural resources on the ground. GRACE has created a unique picture of ...

  • Satellite-based estimation of atmospheric stability parameters in urban and remote areas

    A methodology is presented which can be used to determine atmospheric stability parameters in urban and remote areas where ground-based meteorological observations are not routinely available. The method resolves the surface energy balance by means of satellite remote sensing in an original way. Ground-based data from the FIFE experiment are used to validate parts of the methodology. Results are ...

  • Air temperature retrieval from remote sensing data based on thermodynamics

    A new approach to retrieving air temperature from land surface temperature is presented. The new method is based on thermodynamics. Two important parameters, namely crop water stress index and aerodynamic resistance, were used to build a quantitative relationship between the land surface temperature and the ambient air temperature. The method was applied using MODIS satellite data for a location ...

  • Assessing and monitoring agroenvironmental determinants of recreational freshwater quality using remote sensing

    Diverse fecal and nonfecal bacterial contamination and nutrient sources (e.g. agriculture, human activities and wildlife) represent a considerable non-point source load entering natural recreational waters which may adversely affect water quality. Monitoring of natural recreational water microbial quality is most often based mainly on testing a set of microbiological indicators. The cost and ...

  • Remote sensing and geographic information system for appraisal of salt-affected soils in India

    Received for publication January 23, 2009. Quantification of the nature, extent, and spatial distribution of salt-affected soils (SAS) for India and the world is essential for planning and implementing reclamation programs in a timely and cost-effective manner for sustained crop production. The national extent of SAS for India over the last four decades was assessed by conventional and remote ...

  • Remote sensing of land degradation: experiences from Latin America and the Caribbean

    Received for publication April 6, 2009. Land degradation caused by deforestation, overgrazing, and inappropriate irrigation practices affects about 16% of Latin America and the Caribbean (LAC). This paper addresses issues related to the application of remote sensing technologies for the identification and mapping of land degradation features, with special attention to the LAC region. The ...

  • Application of thermal remote sensing to delineate groundwater discharge zones

    The paper explores whether thermal anomalies at the surface identified by remote sensing allow for the delineation of groundwater discharge zones. The methodology is based on the principle that in shallow groundwater systems, upward fluxes of deep groundwater discharge reduces seasonal temperature variation in layers close to and at the surface. Thermal anomalies were identified by Landsat data ...

  • Salinity monitoring in western Australia using remotely sensed and other spatial data

    Received for publication January 27, 2009. The southwest of Western Australia is affected by dryland salinity that results in the loss of previously productive agricultural land, damage to buildings, roads, and other infrastructure, decline in pockets of remnant vegetation and biodiversity, and reduction in water quality. Accurate information on the location and rate of change of the extent of ...

  • Estimation of stand productivity from multi-angular optical remote sensing

    Global modeling of gross primary production (GPP) is a critical component of climate change research. On local scales, GPP can be assessed from measuring CO2 exchange above the plant canopy using tower-based eddy covariance (EC) systems. The limited footprint inherent to this method however, restricts observations to relatively few discrete areas making continuous predictions of global CO2 fluxes ...
