  2. 1. A Database of Microwave Single Scattering Properties of Ice Hydrometeors

    Author : Robin Nils Ekelund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radar; ice hydrometeors; microwave; scattering properties; sub-millimetre; remote sensing;

    Abstract : Microwave remote sensing by satellites is important for global observations of ice hydrometeors. Interpretation of the measurements requires sufficiently accurate knowledge of hydrometeors’ interaction with photons, i.e.  article scattering and absorption. READ MORE

  4. 2. On the Ionospheric Influence on GNSS Radio Occultation Signals : Modelling and Assessment

    Author : Vinícius Ludwig Barbosa; Mats Pettersson; Viet Thuy Vu; Anthony James Mannucci; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remote Sensing; Radio Occultation; Ionosphere; Scintillation; Wave Optics Propagator; Spectral Analysis; Plasma Bubble; Systemteknik; Systems Engineering;

    Abstract : Radio Occultation (RO) is a well-established remote sensing technique that uses Global Navigation Satellite System (GNSS) signals to sound the Earth’s atmosphere. GNSS-RO measurements provide high-resolution, vertical profiles of physical parameters from the lower atmosphere (troposphere and stratosphere), e.g. READ MORE

  5. 3. Towards synthesis for nitrogen fertilisation using a decision support system

    Author : Sandra Wolters; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Nitrogen (N) fertilisation in crops can be made more efficient by moving from uniform application to meeting variable crop requirements within fields. Within field variable rate N fertilisation of winter wheat (Triticum aestivum L.) is practically feasible using information from web-based decision support systems (DSS). READ MORE

  6. 4. GIS-based decision support systems to minimise soil impacts in logging operations

    Author : Sima Mohtashami; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Mechanised logging operations can leave negative impacts, like ruts, on forest soils. To avoid this, forestry planners and machine operators need decision support systems that can estimate soil trafficability and help to minimise soil impacts. READ MORE

  7. 5. Cross-Correlator Implementations Enabling Aperture Synthesis for Geostationary-Based Remote Sensing

    Author : Erik J Ryman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-custom; signal processing; synthetic aperture; Cross-correlation; interferometric imaging; ASIC; remote sensing;

    Abstract : An ever-increasing demand for weather prediction and high climate modelling accuracy drives the need for better atmospheric data collection. These demands include better spatial and temporal coverage of mainly humidity and temperature distributions in the atmosphere. READ MORE
