  • 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 ...

  • Optical Remote Sensing in the United States

    Recent studies that involve the use of optical remote sensing (ORS) techniques to measure gaseous and particulate pollutants have rekindled interest among environmental researchers and regulators in this decades-old technology. This article describes some of the key research and development projects that are helping restore ORS-based methods to the list of currently available emissions ...

  • 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 ...

  • Agricultural biomass monitoring on watersheds based on remotely sensed data

    There is a close quality relationship between the harmful levels of all three drought indicator groups (meteorological, hydrological and agricultural). However, the numerical scale of the relationships between them is unclear and the conversion of indicators is unsolved. Different areas or an area with different forms of drought cannot be compared. For example, from the evaluation of ...

  • 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 ...

  • 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, ...

  • Predictions in a data-sparse region using a regionalized grid-based hydrologic model driven by remotely sensed data

    The goal of this study was to assess the feasibility of using Tropical Rainfall Measuring Mission (TRMM) and Moderate Resolution Imaging Spectroradiometer (MODIS) products to drive a mesoscale hydrologic model (mHM) in a poorly gauged basin. Other remotely sensed products such as LandSat and Shuttle Radar Topography Mission (SRTM) were also used to complement the local geoinformation. For this ...

  • Spatial and temporal patterns of remotely-sensed and field-measured rainfall in southern California

    Quantification of spatial and temporal patterns of rainfall is an important step toward developing regional hydrological models. However, traditionally used rain gauge data are sparse and do not always provide adequate spatial representation of rainfall. In this study, we evaluated the daily 1-degree resolution remotely-sensed atmospheric precipitation data provided by Global Precipitation ...

  • Radar remote sensing of wind-driven land degradation processes in northeastern Patagonia

    Received for publication February 27, 2009. Wind-driven land degradation negatively impacts on rangeland production and infrastructure in the Valdes Peninsula, northeastern Patagonia. The Valdes Peninsula has the most noticeable dunefields of the Patagonian drylands. Wind erosion has been assessed at different scales in this region, but often with limited data. In general, terrain features caused ...

  • A feasibility of six–hourly rainfall forecast over central India using model output and remote sensing data

    Rainfall forecast has prime importance in an agrarian country like India, wherein the agricultural production is solely dependent on monsoon rainfall. In this paper, an artificial neural network (ANN) technique is used to construct a non–linear mapping between output data from global forecast system (GFS) and rainfall from tropical rainfall measuring mission (TRMM) satellite measurements. The ...

  • Spatial prediction of soil organic matter content using cokriging with remotely sensed data

    Accurately measuring soil organic matter content (SOM) in paddy fields is important because SOM is one of the key soil properties controlling nutrient budgets in agricultural production systems. Estimation of this soil property at an acceptable level of accuracy is important; especially in the case when SOM exhibits strong spatial dependence and its measurement is a time- and labor-consuming ...

  • 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 ...

  • 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 ...

  • Evaluation of remotely sensed snow cover product in Central Asia

    Central Asian countries depend highly on water resources from snow and glacier melt, which has to be studied thoroughly to estimate water availability. However, the observation network in Central Asia is poor to carry out such studies in detail. Observations from space using remote sensing techniques might fill this observation gap, which needs to be validated. Therefore, this study evaluates ...

  • 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 ...
