Dziubanski, David, "Assimilation of AMSR-E snow water equivalent data in a lumped hydrological model" (2013). (2 marks) Snow water equivalent (SWE) is the measurement of how much water is present within a snowpack or the depth of water (mm) that would be produced if the snow melted. Estimation of snow cover and water stored in the snowpack is of great importance in climate change researches and water resources management (Johnson et al. Annual runoff is the Y response or dependent variable, and snow water equivalent is the X explanatory or independent variable. It indicates the water column that would theoretically result should the whole snow pack melt instantaneously and is defined as product between the snow layer’s depth and density. The snow water equivalent production system will be built on the GlobSnow SWE production system and will be further developed by improving various aspects of the processing chain, including time variable snow density, influence of land cover and implementation of techniques for enhancement of brightness temperature resolution. Disclaimer 2019 Nov 18;19(22):5023. doi: 10.3390/s19225023. AMA Style. It can be thought of as the depth of water that would theoretically result if you melted the entire snowpack instantaneously. Snow Water Equivalent (AMSR-E) The Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E) distributes daily, weekly, and monthly products which includes snow water equivalent. Please wait. Questions? -2 . Another way to think of it is if all the snow were melted instantaneously, it would be the depth of that water. The SWE boundary is more uniform then one would expect for northern hemisphere snow cover and … Figure 2. 1984; Yasunari et al. SWE essentially represents the depth of water (mm) that would be produced if the snow melted. Compare that to last year which had around 2 inches at the same stage. Although historical satellite sensors have provided SWE retrievals for about 40 years, the utility An overview of the current NASA operational AMSR-E/AMSR2 snow science team activities Abstract: The knowledge of snow depth (SD) and snow water equivalent (SWE) is fundamental for water resources management and weather and flashflood forecast, among other things. For example, 10 depth units of snow with a liquid equivalent of 20% will melt and become 2 units deep. Snow Water Equivalent (SWE) is a common snowpack measurement used in hydrology and avalanche forecasting. Atmospheric Water Vapor, Descending Passes. The depth of water produced if a snow cover is completely melted on a horizontal surface is known as the snow water equivalent or SWE. % of Normal Peak: The current value as % of the normal seasonal peak for the year. It can be considered as the depth of water that would theoretically result if the whole snow pack instantaneously melts. AMSR2 snow retrieval algorithm requires AMRS2 brightness temperatures between10GHz to 89GHz at their native resolutions.

Definitions: Snow Water Equivalent (SWE): The liquid water equivalent of the snowpack, expressed in terms of depth. Loading form. Snow Water Equivalent is one of the primary measurements taken at SNOwpack TELemetry (SNOTEL) and snowcourses across the western United States. Most snowpack reports issued by the Natural Resource Conservation Service (NRCS) use SWE to summarize snowpack conditions for spring and summer water supply forecasting. Why not use Snow Depth? NOTE: We have identified a potential irregularity in the AMSR-U2 Snow Water Equivalent data set. White areas show the highest values (more than 250 mm) while dark, blue-gray areas show low values (down to 1 mm). Measurement Range Resolution Accuracy Operating Temperature Range SR50A-L Sonic Distance Sensor Popular Snow and Precipitation Update Reports - Current, average, and % of average; Basin Data Reports - Select "Snowpack" as report type; Maps SNOTEL and Snow Course SWE, Snow Depth, and Snow Density AMSR2 is a successor to AMSR on Japanese ADEOS-II and AMSR-E on Aqua, a NASA satellite. These products have been refined through ongoing evaluations and reprocessings of the AMSR-E record to support global water… This data should NOT be relied on for any operational use as data gaps can occur due to hardware failure and/or model upgrading procedures. The sea ice data derived from AMSR-E using the ARTIST sea ice (ASI) algorithm offer a factor of 4 finer spatial resolution than most sea ice data sets from passive microwave satellite instruments. SWESARR radar system development is the focus of current efforts to provide a state-of-the-art microwave snow measurement system.
