Activity Description

2002  

  • "Fundamentals of Remote Sensing and Airphoto Interpretation"

    This book, published by Graydon Lennis L. Berlin and Thomas Eugene Avery, Prentice Hall Publishers, 6th Edition, contains contributions of this science team on modeling and remote sensing research.

2004  

  • LAB Materials for Remote Sensing Short Course

    Drs. Dar Roberts (UCSB) and Carlos Moreira de Souza Jr.(IMAZON) developed lab materials for remote sensing short courses.

    General topics include:

    • Remote Sensing background
    • Examples of Land-Cover Change
    • Mixture Models
    • Decision Tree Classifiers

Year
Completed
Activity Description

2001  

  • Training of IMAZON scientist at UCSB

    The IMAZON scientist, André Monteiro, visited the University of California-Santa Barbara for a six-month training in image processing techniques designed to provide reflectance retrievals, spectral mixture analysis with reference end member selection, land-cover mapping and decision tree classifiers.

2004  

  • INPE's scientists visit UCSB

    At the end of January 2004, Dr. Camilo Dalales Renno and Dr. Joao Vianei Soares visited the University of California-Santa Barbara.

    The main goal was to begin an analysis in which a distributed hydrological model, developed by Dr. Renno, will be used to estimate the impacts of land-cover change on evapotranspiration and run-off in a pair of water sheds. The primary objective was to select paired watersheds in Rondônia (one cleared, one relatively pristine), which include extensive historical remote sensing time series and meet model requirements (extent feasible with high quality stream gauge data for calibration/validation, soils etc).

    The group also discussed plans for additional data layers, such as seasonal LAI derived from MODIS time series.

Science Questions:

Carbon Dynamics:

        CD-Q3b - How does selective logging change the storage and cycling of carbon in forests?

Land Cover and Land Use Change:

        LC-Q1 - What are the rates and mechanisms of forest conversion to agricultural land uses, and what is the relative importance of these land uses?
        LC-Q2 - At what rate are converted lands abandoned to secondary forests; what is the fate of these converted lands, and what are the overall dynamic patterns of land conversion and abandonment?
        LC-Q3 - What is the area of forest that is affected by selective logging each year? How does the intensity of selective logging influence forest ecosystem function, thus altering forest regrowth and flammability?

Nutrient Dynamics and Surface Water Chemistry:

        ND-Q1 - How do stocks, cycling rates and budgets of carbon and important elements nitrogen, phosphorus, potassium, calcium, magnesium, and aluminum change under different land covers and land uses?
        ND-Q2 - Are nutrients major factors that control the rates of regrowth and carbon accumulation in abandoned pastures and regrowing secondary forests?
        ND-Q4 - How do changes in land use and climate alter the stocks, processes and fluxes of dissolved and particulate organic matter, nutrients, and trace gases from the uplands across the riparian zones and floodplains and down the channels of river corridors?
        ND-Q4a - How will the composition and quantity of nutrients and organic matter entering and being processed within streams be altered under different land-use change scenarios?
        ND-Q4b - Are there unique signatures that can be traced downstream?
