  1. 100. Studying the effects of forest water dynamics using the BorealScat-2 tower-based multi-frequency and tomographic radar

    Soil and Hydrology

    BorealScat-2 is a new tower-based tomographic radar experiment located in a boreal forest site in northern Sweden which acquires data in the frequency bands from P- to C-band. It is of similar design as its predecessor BorealScat except that the antenna frame (P- to L-band) can be moved along a 4 m aperture. The moveable frame increases the number of independent samples, thus reducing...

  2. 104. Analysing the sensitivity of Sentinel-1 SAR to water dynamics in vegetation in a combined model approach

    Forestry

    Changes in plant phenology as for example earlier leaf unfolding and delayed autumn senescence can result in variations in the carbon and water cycle. Studies investigating the impact of phenological shifts on biophysical processes such as water availability are still limited. Due to the sensitivity of radar satellite observations to both, structural and dielectric properties of the scattering...

    Soil and Hydrology

    SAR is increasingly used in the fields of agriculture, forestry, soil moisture and hydrology, providing finer spatial resolution information than passive microwave remote sensing and scatterometry. However, there is an emerging demand for SAR imagery at finer temporal scales. Specifically, there is an observation gap at sub-daily scales. While SAR imagery is theoretically available from...

  4. 84. HIGH RESOLUTION MAPPING OF SOIL MOISTURE AND VEGETATION BIOMASS USING X- AND C- BAND SAR AND MACHINE LEARNING

    Soil and Hydrology

    This study deals with the high-resolution mapping of soil moisture (SMC) and crop biomass (expressed as plant water content PWC) in agricultural fields by using SAR data at C and X bands.
    For this purpose, timeseries of Sentinel-1 (S-1, at VV and VH polarizations) and COSMO-SkyMed (CSK, StripMap Himage at HH polarization) images have been collected for some years in an agricultural area...

  5. 77. High spatio-temporal soil moisture retrieval over agricultural fields using a microwave radiative transfer model framework

    Soil and Hydrology

    Soil moisture plays a key role in land surface processes such as water, carbon and energy fluxes. SAR satellites, like Sentinel-1, have proven to be particularly useful to derive high spatio-temporal soil moisture estimates. Thus, microwave radiative transfer models are often used to derive soil moisture estimates from SAR satellites. But, as the derivation of soil moisture, especially over...
