  • Changes in snow depth in Norway during the period 1961–2010

    Observed trends in annual maximum snow depth (SD) in Norway are analyzed and examined in the context of changes in winter climate from 1961 until today. Trends are evaluated for the 50-year period (1961–2010) and for three 30-year periods (1961–1990, 1971–2000, 1981–2010). The analyzed dataset is the most extensive and geographically representative for the country so ...

It represents an advancement of the SHM30, which came onto the market in mid-2009. New snow height sensor SHM31 compared to its predecessor SHM30 ...

  • Weather SDM: estimating snow density with high precision using snow depth and local climate

    Snow density is an important measure in hydrology used to convert snow depth to the snow water equivalent (SWE). A model developed by Sturm, Tara and Liston predicts the snow density by using snow depth, the snow age and a snow class defined by the location. In this work this model is extended to include location and seasonal weather-specific variables. The model is named Weather Snow Density ...

  • Response of the Indian summer monsoon circulation and rainfall to seasonal snow depth anomaly over Eurasia

    Several observational and modeling studies indicate that the Indian summer monsoon rainfall (ISMR) is inversely related to the Eurasian snow extent and depth. The other two important surface boundary conditions which influence the ISMR are the Pacific sea surface temperature (SST) to a large extent and the Indian Ocean SST to some extent. In the present study, observed Soviet snow depth data and ...

  • Analysis and modelling of snow bulk density in the Tyrolean Alps

    An extensive collection of in-situ snow measurements is used to characterize snow conditions in the entire elevation range of the alpine area of Tyrol, Austria. Regularly observed snow station data are evaluated with respect to mean snow density–time curves of the period 1952–2010. Dependent on the observed snow depth (HS), the snow bulk density (ρ) is ...

  • Arctic snow distribution patterns at the watershed scale

    Watershed-scale hydrologic models require good estimates of spatially distributed snow water equivalent (SWE) at winter's end. Snow on the ground in arctic environments is susceptible to significant wind redistribution, which results in heterogeneous snowpacks. The scarcity and quality of data collected by snow gauges provides a poor indicator of actual snowpack distribution. Snow ...

  • A model for the snow water equivalent derived from stratigraphy observations in northern Sweden

    A new parameterization of snow water equivalent (SWE) based on snow depth (HS) has been developed from observations made in northern Sweden. When applying previous SWE parameterization from the Alps on observations from northern Sweden, the SWE values are systematically 20% lower. The new SWE parameterization is derived from a snow layer density regression model using snow layer hardness and ...

  • Evaluation of remotely sensed snow cover product in Central Asia

    Central Asian countries depend highly on water resources from snow and glacier melt, which has to be studied thoroughly to estimate water availability. However, the observation network in Central Asia is poor to carry out such studies in detail. Observations from space using remote sensing techniques might fill this observation gap, which needs to be validated. Therefore, this study evaluates ...

  • Snow cover mapping using IRS-P6 AWiFS data and the relationships between some climatic factors with snowpack in the northwest of Iran

    In this study, we explored the potential of the multispectral and multi-temporal IRS Advanced Wide Field Sensor (AWiFS) data for mapping of the snow cover in the northwest regions of Iran. The AWiFS snow cover maps, based on the unsupervised classification method, were compared with the estimates of snow cover area derived from the moderate resolution imaging spectroradiometer (MODIS) images ...

  • Intersolar Europe 2017 in Munich: Swabian solar experts united at booth A3.460

    This year’s Intersolar Europe, the world’s leading exhibition for the solar industry and its partners, will take place between May 31 and June 2, 2017 at the Neue Messe München – and we will be on-site for you! You can find us on the joint booth of Baden-Württemberg International with the number A3.460. Here we present a selection of our ...

  • Groundwater recharge during spring thaw in the Prairie Pothole Region of North America

    Snowmelt governs recharge in the Prairie Pothole Region of North America, but little is known about the soil at the time of recharge. Depth of snow, surface water, water table, and frozen soil were measured within a 2-ha landscape depression in Minnesota during spring thaw in 2000 and 2001. The water table rose by at least 1 m within 24 h after a pond formed within the landscape depression as a ...

  • Spatial and temporal characteristics in streamflow-related hydroclimatic variables over western Canada. Part 2: future projections

    Much of the freshwater in western Canada originates in the Rocky Mountains as snowpack. Temperature and precipitation patterns throughout the region control the amount of snow accumulated and stored throughout the winter, and the intensity and timing of melt during the spring freshet. Therefore, changes in temperature, precipitation, snow depth, and snowmelt over western Canada are examined ...

  • National Energy Technology Laboratory - USA

    The National Energy Technology Laboratory site in Morgantown, West Virginia, USA, maintains a 150-foot free standing meteorological tower with data collection points at ground level, 33 feet, 75 feet, and at 150 feet. The data collected at ground level is Air Temperature, relative humidity, total rainfall, and snow depth. The other stations monitor wind direction and speed. Additionally, air ...

  • Interpretation of statistics of lake ice time series for climate variability

    Lake ice time series consist of the dates of freezing and ice break-up for the ice phenology, and ice coverage and ice thicknesses for the severity of ice seasons. This work analyses the physical interpretation of the statistics of lake ice time series illustrated by available data. The results provide tools to understand variations in the past lake ice seasons and to make projections into the ...

  • A novel freeze protection strategy for shallow buried sewer pipes: temperature modelling and field investigation

    The burial of sewer and water pipes below the maximum ground frost depth can be very costly and laborious in regions with cold winters. If a freeze protection measure is applied, the utility lines can be installed in a shallower trench to reduce the excavation needs. One freeze protection measure, so called heat tracing, consists of supplying heat along the pipes. In this work, the use of 4th ...
