merra2 snow water equivalent

The radiometer has been in development through ESTO-IIP funds since 2010. To anticipate these impacts, prospective studies may use wind power production simulations in the form of 1 h or 30 min time series that are often based on reanalysis wind-speed data. near record water levels on lake superior have lowered, but are still running higher than normal. Its units are metres of water equivalent, so it is the depth the water would have if the snow melted and was spread evenly over the whole grid box. Recommendation: Users should consider the issue when using affected parameters. Area I download for GFS forecasts: leftlon=-55, rightlon=20, toplat=70, bottomlat=30 MERRA2 Data… Skip to the content [1] We used daily remotely sensed fractional snow-covered area (SCA) at 500 m resolution to estimate snow water equivalent (SWE) across the Upper Merced and Tuolumne River basins of the Sierra Nevada of California for 2004 (dry and warm) and 2005 (wet and cool). Therefore, as we have The standard method of measuring water equivalent is by gravimetric measurement using a snow tube to obtain a sample core (WMO, 2008). Depth of snow from the snow-covered area of a grid box. It is the amount of water contained within the snowpack. Dyn., 53, 5203–5213, 2019. Snowhland: water equivalent snow depth. The data cover the Earth on a 30km grid and resolve the atmosphere using 137 levels from the surface up to a height of 80km. current snow water equivalent values are well below values at this time last year, except for across the keweenaw peninsula. Underestimate Snow Water Equivalent? ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables. MERRA vs. GEOS-5 LWI (land-water-ice flags) SNOMAS. 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. pkg:[package-name] User packages @[username] NCCS-Enabled Science Advances Being Presented at Online AMS Annual Meeting. Abstract: Melt water runoff from seasonal snow in the High Atlas range is an essential water resource in Morocco. [Zhang et al., 2016]. Snow Water Equivalent (SWE) is a common snowpack measurement. MERRA-Ocean 2. MERRA-2 is a NASA atmospheric reanalysis integrating satellite data assimilation and aims at historical climate analyses. Quality-assured monthly updates of ERA5 It spans the satellite observing era from 1980 to the present. Snow Water Equivalent (SWE) is a common snowpack measurement. Density for the snowpack is calculated by dividing the snow water equivalent by the depth of the snow. Aside from this you can use the modeled temperature in 850 hPa (5000 ft a.s.l.) water, and the overall precision (standard deviation of retrieval errors) for high quality AOD over land is 0.112 and 0.046 over water. MERRA MERRA-2 System Evolution Updates to the model, analysis, observations •Cubed-sphere dynamics •Updated physics: convection, re-evap of rain, sublimation of snow •Improved glacier model and cryosphere albedos •More observations: through MetOp-B/SNPP, GPSRO, Aura OMI/MLS •New moisture control variable •Bias correction for aircraft temperature observations Hydrol. The Global Imagery Browse Services (GIBS) system is a core EOSDIS component which provides a scalable, responsive, highly available, and community standards based set of imagery services. The incorporation of satellite-observed aerosols in MERRA-2 is based on the “MERRAero” off-line product that was produced using meteorological fields from the original MERRA. California Nevada River Forecast Center (CNRFC) Snow Water Equivalent / Snow Depth Summary - Interactive Map Interface. MERRA-2 data were downscaled to 250-m spatial resolution using a digital elevation model. Temperature. the possibility of using a slightly coarser spatial resolution forcing data (MERRA2) to extend the dataset to the near present. Viewed. This measurement can be used to determine snow depth. Canadian historical Snow Water Equivalent dataset (CanSWE, 1928–2020) Vincent Vionnet, Colleen Mortimer, Mike Brady, Louise Arnal, and Ross Brown. 15 = MODIS cloud mask only, cloudy over polar regions. The NASA Earthdata data discovery and data access webinars span the Earth science disciplines and are designed to help users learn about NASA EOSDIS data, services and tools and show users how to work with these data resources. Medians and averages are calculated for the period 1981-2010. With regard to annual days of snow cover, the CRCM5 generally provides a good reproduction of the observed annual series at each of the six stations although a slight overestimation is observed. It is downscaled from MERRA2 reanalysis datasets. Cryosphere 12 , … Collaborative REAnalysis Technical Environment (CREATE) — Incorporating a multitude of reanalyses together … The SNOMAS field in MERRA differs from that in the GEOS-5 operational data: From the GEOS-5 File Specification Document: SNOMAS: The mass of snow in per unit of land area in meters of liquid-water-equivalent depth (i.e., 10^3 kg/m2). recent rainfall and unseasonably warm temperatures has further diminished snowpack and swe across upper michigan. Snow Water Equivalent 30-Year Averages (1981-2010) How much do you like this book? Water vapor is a significant greenhouse gas that affects both radiative and dynamic properties of the Earth's atmosphere. Global water vapor (H2O) measurements from Microwave Limb Sounder (MLS) are used to evaluate upper tropospheric (UT) and lower stratospheric (LS) H2O products produced by NASA Modern‐Era Retrospective Analysis for Research and Applications (MERRA), its newest release MERRA2, and European Centre for Medium‐Range Weather Forecasts (ECMWF) Interim … MERRA-2 Weather Maps - Precipitation Type. ODAS. NOHRSC Mission Statement | Contact: National Weather Service National Operational Hydrologic Remote Sensing Center Office of Water Prediction 1735 Lake Drive W. Chanhassen, MN 55317: Contact NOHRSC MERRA-2 covers Land Surface Diagnostics for the period 1980-present at 0.5 ° x 0.625 ° spatial- and 1-hourly temporal-resolution. This data set is a daily gridded terrestrial snow water equivalent (SWE) dataset based on five component SWE products: GlobSnow combined SWE product (passive microwave/ground-based weather station, version 2) ERA-Interim/Land reanalysis SWE product MERRA reanalysis SWE product Crocus SWE data set: output from the Crocus snowpack model, driven by ERA-Interim meteorology … Snow Water Equivalent! 11 = MOPITT only, cloudy (when MODIS data missing) 12 = First 2 stares in a packet discarded (obsolete for V3) 13 = MOPITT and MODIS cloud mask agree on cloudy. (bottom) 10m wind speeds and direction from MERRA2 for November 5-7, 2006 showing the flow of winds from the Barents-Kara seas onto the Yamal Peninsula during the rain-on-snow event. ... Possible impact of North Atlantic warming on the decadal change in the dominant modes of winter Eurasian snow water equivalent during 1979–2015, Clim. 14 = MOPITT clear, MODIS cloudy and failed low cloud tests. 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. In this work we assessed the performance of ERA5 and MERRA-2 climate reanalysis … Package details. We are implementing an array of forecasting methods that integrate state-of-the-art mechanistic models and statistical methods. White areas show the highest values (more than 250 mm) while dark, blue-gray areas show low values (down to 1 mm). Lagrangian Snow Distributions for Sea-Ice Applications, Version 1 USER GUIDE ... MERRA2 = Modern Era Retrospective‐Analysis for Research and Applications‐Version 2 01Aug1980- ... wind direction, and water-equivalent precipitation. Numerical maps of snow water equivalent are automatically produced for subareas of a river basin by combining drone-based snow depth maps with snow density estimates.
