 1. The Global Distribution of Freshwater Wetlands, 1995 (ds764.0)

Global distribution of freshwater wetlands, both 1x1 degree resolution interpolated at NCAR, and the original Anselman & Crutzen 2.5x5 degree resolution.

 2. Global Monthly Streamflow Time Series (ds556.0)

Copy of CD - Global Streamflow Time Series, v.1.0 (a global hydro-climatic data network) Michael Dettinger (USGS) and Henry Diaz (CDC) (Journal of Hydrometeorology, I(4), 289-310, August 2000 This set ...  has been included in ds552.1.

 3. Monthly Canadian Riverflow Data (ds554.0)

This dataset contains monthly riverflow data for stations (gauges) on Canadian rivers and streams.

 4. Monthly Discharge Data for World Rivers (except former Soviet Union) (ds552.1)

This dataset contains monthly river discharge rates for 4,425 locations around the world except for the former Soviet Union. This dataset combines the UNESCO set (ds552.0) plus 3,455 gages, thus, ...  improving spatial coverage over much of the world with major gains in Brazil, Australia and Argentina. The "new" gauges have not been subjected to the rigorous comparisons of the benchmark UNESCO portion. Their locations, names, and drainage areas have been edited; and obvious errors (e.g., egregious extremes, replicates) removed from flow rates. Data sources and the edits are documented.

The USGS offers a CD-ROM "Hydro-Climatic Data Network: Streamflow Data Set, 1874-1988". This consists of streamflow data measured at 1659 sites throughout the US and its territories. Daily mean, monthly mean, annual mean, minimum and maximum values of discharge are given for each water year. Stations selected distinguish human influences. For more information contact J.R. Slack (jrslack@usgs.gov).

 5. Russian River Flow Data by Bodo, Enhanced (ds553.2)

Monthly river flow rates for Russia and former Soviet Union countries in ds553.1 are augmented with data from Russia's State Hydrological Institute (SHI) and a few sites from the Global  ...  Hydroclimatic Data Network (GHCDN) . This compendium (v1.1 September 2001) includes 2458 gauges spanning all major river and oceanographic basins of the entire former Soviet Union. Exact dates vary by station. See the inventories for detailed information. Records are generally long: mean length is 36.3 yrs and 1,724 (70%) gauges have 25 or more years of data. 1,373 gauges have data to 1985 and another 909 gauges also have some data from 1986-1995. 640 gauges represent watersheds of 10,000 or more sq km, and 1,055 gauges represent catchments of 1,000-9,999 sq km. The SHI additions have not been scrutinized as rigorously as ds553.1.

 6. Russian River Flow Data by Bodo (ds553.1)

Monthly River flow rates for Russia and former Soviet Union countries prepared by Byron Bodo (babodo@eol.ca) whereby data were combined from ds552.0 (UNESCO and GRD sets) and ds553.0 (Russian set ...  from US-USSR exchange project). Exact dates vary by station. See the inventory for detailed information. Data validation involved corrections which are documented. This is an update of the March 1999 version.

 7. Flow Rates of World Rivers (excluding former Soviet Union countries) (ds552.0)

Monthly river flow rate data for most of the globe except former Soviet Union countries, which can be found in ds553.1. This compilation was prepared by Byron Bodo (babodo@eol.ca),  ...  Jul 2001; it succeeds the Feb 2001 update. This is a combination of datasets from UNESCO, WMO GRDC, the RIVDIS by Vorosmarty (1998), and others. Changes for this version are primarily to documentation, however, there are updates to one Thai and two Bolivian gauges plus replacement of some UK provisional data; details are given in the documentation.

Average record length is about 26.7 years. About 2/3 of the records have from 10-100+ years of data.

The USGS offers the CD-ROM "Hydro-Climatic Data Network: Streamflow Data Set, 1874-1988". This consists of streamflow data measured at 1659 sites throughout the US and its territories. Daily mean, monthly mean, annual mean, minimum and maximum values of discharge are given for each water year. Stations selected distinguish human influences. For more information contact J.R. Slack (jrslack@usgs.gov).

 8. Dewey and Heim's Northern Hemisphere Snow Cover, Weekly and Monthly 1966Nov-1991Dec (ds315.0)

This dataset, from the National Snow and Ice Data Center, contains weekly and monthly grids of snow cover fields for November 1966 through December 1991. The data values (indicating ...  snow cover/no snow cover) are available on a 190.5 km resolution polar stereographic grid covering the Northern Hemisphere. Data were derived from NMC and Navy maps by Dewey and Heim at NOAA.

 9. Daily and Monthly Texas Surface Observations, 1898-1975 (ds510.2)

Daily and monthly surface observations for Texas stations for January 1898 to December 1975.

 10. A Quality-Controlled Dataset for Long-Term U.S. Snowfall Trends (ds510.5)

NCDC's U.S. Cooperative Summary of Data (DSI3200) dataset was screened for stations with long continuous observations for use in assessing 20th-century U.S. snowfall trends. The result is a subset of ...  424 stations with quality-controlled snowfall, precipitation, and temperature data for snow-season months (October through May). Most of the stations have observations that begin prior to the winter of 1930-31, making for station periods of longer than 77 winters. Several stations have data as far back as the 1890s.
