   Abstract : Water is essential for human well-being and healthy ecosystems, but population growth and changes in climate and land-use are putting increased stress on water resources in many regions. To ensure water security, knowledge about the spatiotemporal distribution of these resources is of great importance. READ MORE

4. 17. Modelling of the daytime and night-time urban thermal environment

   Author : Shiho Onomura; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; urban thermal environment; microclimate modelling; air temperature; mean radiant temperature; nocturnal cooling rates; synoptic weather types;

   Abstract : The world’s urban population is expected to increase over the coming decades. To maintain and improve the health and well-being of urban citizens, it is important to increase our knowledge and develop methods for evaluating the urban thermal environment to support urban planning.

5. 18. Climatology and firn processes in the lower accumulation area of the Greenland ice sheet

   Author : Charalampos Charalampidis; Veijo Pohjola; Dirk van As; Rickard Pettersson; Douglas Benn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; Greenland ice sheet; accumulation area; automatic weather stations; surface energy balance; melt–albedo feedback; surface mass budget; snow; firn; meltwater; percolation; refreezing; runoff;

   Abstract : The Greenland ice sheet is the largest Northern Hemisphere store of fresh water, and it is responding rapidly to the warming climate. In situ observations document the changing ice sheet properties in the lower accumulation area, Southwest Greenland. READ MORE

6. 19. Advanced Remote Sensing Precipitation Input for Improved Runoff Simulation : Local to regional scale modelling

   Author : Seyyed Hasan Hosseini; Avdelningen för Teknisk vattenresurslära; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Precipitation; Rainfall; Satellite; Runoff; Streamflow; Rainfall-runoff modelling; X-band weather radar; GPM-IMERG; MODIS Terra;

   Abstract : Accurate precipitation data are crucial for hydrological modelling and rainwater runoff management. Precipitation variability exists through a wide range of spatial and temporal scales and cannot be captured well using sparse rain gauge networks. READ MORE

7. 20. Air mass boundary identification : improvement of precipitation phase determination in surface based modeling

   Author : James Feiccabrino; Per-Erik Jansson; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

   Abstract : Snowpack properties derived from hydrological models play an important role for many ecological, water resource, and climate applications; such as winter survival of plants, reindeer, small mammals and birds, avalanche hazards, glaciers and polar ice accumulation, growth of sea and lake ices, climate change, snow melt flooding etc. These hydrological models need accurate precipitation phase discrimination schemes to closely portray e.
