Available Data across NEESPIStreamflowMonthly discharge database of basins varying in size, with varying temporal coverage beginning in the 1930s through near real-time. Near real-time data for some of the basins are found at Arctic RIMS, which also hosts a variety of gridded hydrological and hydrometeorological data. Some stations are available with daily measurements on ArcticRIMS. Database of streamflow for major river basins globally. Temporal coverage varies, but in general data stops in the 1980s. Discharge data for the former Soviet Union. Contains the same as RivDis, but is organized by country rather than tiles Precipitation & Atmospheric MeasurementsStation data for 2190 stations across the former Soviet Union, with some stations extending as far back as the 1880s. Data ends in 2001 with updates ongoing. Archived at the NCDC (Datasets TD-9290 and TD-9813) and processed by Pasha Groisman. Dataset TD-9290 includes data for atmospheric variables other than precipitation (pressure, humidity, etc.). UW's EASE-grid Forcing ProductDaily forcing dataset for the NEESPI domain, 1930-2000. Contains daily precipitation, maximum and minimum temperature, and wind speed. Dataset begins with monthly precipitation and temperature data from the CRU dataset, and then long-term and short-term variability are imposed, and trends are made consistent with Pasha Groisman's station trends. For more information, see Adam et al., J. Climate, 2007.
Global forcing dataset at daily and 3-hourly temporal resolution (1948-2006). Daily data contains precipitation, maximum and minimum temperature, and wind speed. 3-hourly data includes precipitation, temperature, vapor pressure, atmospheric pressure, wind speed, and downward shortwave and longwave radiation. Spatial resolution is at 1 degree, and has been interpolated to the EASE-grid for the NEESPI domain. 1948-2000 has been processes for inhomogeneities in the data; this has not been done for post-2000 (as of June 2008). Remote sensing-based product from 1979-2001 at 1/2 degree spatial resolution. Contains total column water vapor as well as water vapor for different atmospheric levels. SnowWeekly snow cover extent derived from satellites from 1966 through the present. It is at a 25km EASE-grid resolution covering the Northern Hemisphere. Russian snow surveys from 1966 through 1996 measured snow depth and snow water equivalent. Snow depths were measured at both stations and transects, and snow water equivalent was measured across transects. Between 1996 and 1990, measurements were taken at 1,345 sites, and at 146 of those sites after 1991. Soil MoistureSoil moisture archive by land cover type (grass, forest, etc.) across the former Soviet Union. Data from the Valdai PILPS experiment can also be found here. Soil Temperature/ALTCollection of 125 sites across the circumpolar Arctic that are monitoring active layer thickness. Measurements are taken on a 100m x 100m grid or 1000m x 1000m grid. The project began in 1991 and continues through the present.
Soil temperature dataset, with measurements down to 3.2m, compiled by Romanovsky et al. (2003) and archived at the NSIDC. In general, the data for the 35 stations covers the period from the 1950s through the 90s, but some stations' records extend back to 1882.
The 263 stations in this dataset cover the former Soviet Union, with some stations extending back to the 19th century. At most stations, data collection began in the 1930s and 1950s. Land Cover/Land Use1km resolution land cover product (Bartalev et al., 2003) across Northern Eurasia, derived from SPOT-IV remote sensing data for the year 2000. Compared favorably across the western Siberian lowlands, partially because it contained a bog class, which global land cover products do not. Used for my VIC simulations. Ground Observations across Western Siberian Lowlands2161 observations taken during field work across the western Siberian Lowlands. Land cover observations were recorded wherever there was a clear view for 1km. Data published by Karen Frey and Larry Smith in Global Biogeochemical Cycles, 2007.
Reanalysis ProductsGlobal reanalysis product with atmospheric and land surface hydrological variables from 1958-2002. There is an ongoing product to near real-time, but this might have consistency issues with the ERA-40 product (inhomogeneities, etc.). The grid size is 2.5 degrees with a smaller resolution available for download. It is also archived at NCAR. One should be very careful about using this product for trends, as measurements are included whenever available, regardless if it's only for a portion of the reanalysis period. Global reanalysis product from 1948 to real-time. There are some spurious wave-like patterns in some of the at high-latitudes (e.g. number of rain days per month), so care should be taken when using this product across NEESPI. It also suffers from the problems of the ERA-40 for trends - measurements are included whenever available. |
