  1. 1. Studies in Glacier Mass Balance : Measurement and its errors

    Författare :Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; naturgeografi; Physical Geography;

    Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER

  2. 2. Seeing and Knowing the Earth as a System : An Effective History of Global Environmental Change Research as Scientific and Political Practice

    Författare :Ola Uhrqvist; Eva Lövbrand; Bjön-Ola Linnér; Sabine Höhler; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURVETENSKAP; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; SOCIAL SCIENCES; Earth system; Global change; Governmentality; History of the present; history of environmental science; Jordsystemet; Globala miljöförändringar; Governmentality; nuets historia; miljövetenskapernas historia; internationella forskningsprogram; miljöpolitik;

    Sammanfattning : Previous research connecting scientific knowledge production with governing of the global environment usually start in international climate change negotiations and related assessments. From that vantage point Earth system science and models are studied as an expansion of Global Circulation Models. LÄS MER

  3. 3. How on Earth : Operationalizing the ecosystem service concept for local sustainability

    Författare :Katja Malmborg; Lisen Schultz; Albert Norström; Elin Enfors-Kautsky; Erik Gomez-Baggethun; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Ecosystem service bundles; System dynamics; Participatory methods; Usable knowledge; Leverage points; Learning; Complexity; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : Ecosystem services are co-produced in social-ecological systems. Due to their social-ecological framing, ecosystem services hold the potential to be a concept around which different stakeholders with vested interests in different aspects of landscape management can meet.

  4. 4. Introducing Surface Gravity Waves into Earth System Models

    Författare :Lichuan Wu; Anna Rutgersson; Erik Sahlée; Peter Janssen; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Surface gravity waves; Air-sea interaction; Earth-System Model; Atmospheric mixing; Upper-ocean turbulence; Meteorology; Meteorologi;

    Sammanfattning : Surface gravity waves alter the turbulence of the bottom atmosphere and the upper ocean. Accordingly, they can affect momentum flux, heat fluxes, gas exchange and atmospheric mixing. However, in most state-of-the-art Earth System Models (ESMs), surface wave influences are not fully considered or even included. LÄS MER

  5. 5. Geospatial Knowledge Discovery using Volunteered Geographic Information : a Complex System Perspective

    Författare :Tao Jia; Bin Jiang; Yifang Ban; Itzhak Benenson; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; knowledge discovery; urban systems; complex system; VGI; OSM; GPS tracking dataset; scaling; heavy-tailed distribution detection; urban sprawl; Zipf’s law; human activity mobility patterns; agent-based modeling; complex network.;

    Sammanfattning : The continuous progression of urbanization has resulted in an increasing number of people living in cities or towns. In parallel, advancements in technologies, such as the Internet, telecommunications, and transportation, have allowed for better connectivity among people. LÄS MER
