BOREAS Feb 21 Release

Another 14 data sets from the Boreal Ecosystem-Atmosphere Study (BOREAS) were added to the ORNL DAAC's offerings as of February 21.

The newest data sets contain tower flux and meteorological data, remote-sensing images, data and geographic information system (GIS) coverages related to forest cover, and measurements of soil characteristics.

BOREAS was an intensive remote-sensing and field study of a Canadian boreal forest. Investigators measured exchanges of energy, water, heat, carbon dioxide, and trace gases between the forest and the atmosphere from 1993 to 1996.

BOREAS Jan 27 Release

The ORNL DAAC released 12 new data sets from the Boreal Ecosystem/Atmosphere Study (BOREAS) on January 27. This release brings the total number of published BOREAS data sets to 247.

The newest data are related to upper air fluxes and meteorology, remote sensing images, aircraft flight information, and tower flux data.

BOREAS was an intensive remote-sensing and field study of a Canadian boreal forest. Investigators measured exchanges of energy, water, heat, carbon dioxide, and trace gases between the forest and the atmosphere from 1993 to 1996.

Global River Discharge Database (RivDIS)

Using the Global River Discharge (RivDIS) Database has become a whole lot easier. The ORNL DAAC has divided RivDIS, Version 1.1, into separate station files so that users can readily find information by country, river, and station. We have also generated a set of useful plots and tables for each station.

RivDIS contains monthly discharge measurements from 1018 stations around the world. The period of record ranges from 1807 to 1991.

BOREAS Dec 17 Release

The ORNL DAAC released 12 new data sets from the Boreal Ecosystem/Atmosphere Study (BOREAS) on December 17. This release brings the total number of published BOREAS data sets to 235.

The newest data sets contain remote sensing images, modeling results, and terrestrial ecology measurements.

BOREAS was an intensive remote-sensing and field study of a Canadian boreal forest. Investigators measured exchanges of energy, water, heat, carbon dioxide, and trace gases between the forest and the atmosphere from 1993 to 1996.

Search for Flux Publications

The ORNL DAAC has developed a searchable database containing more than 3000 bibliographic citations related to the FLUXNET project.

FLUXNET is an international effort to provide consistent, integrated measurements of carbon dioxide, water vapor, and energy fluxes, as well as characteristics of vegetation, soil, hydrology, and meteorology that are associated with the fluxes. Data are collected from regional networks and independent sites around the world.

NPP 16

Another 13 study sites, plus three worldwide data sets, have been added to the global terrestrial Net Primary Production (NPP) reference database. The NPP database has been compiled by Dick Olson and Jonathan Scurlock under the auspices of the International Geosphere-Biosphere Programme, with funding from the Terrestrial Ecology Program of NASA's Office of Earth Science.

BOREAS Nov. 12 & 16 Release

The ORNL DAAC released 26 new data sets from the Boreal Ecosystem-Atmosphere Study (BOREAS) on November 12 and 16, 1999. These releases bring the total number of published BOREAS data sets to 212.

The newest data are related to airborne fluxes and meteorology, remote sensing, terrestrial ecology, and background measurements (called "staff science").

BOREAS Oct. 15 Release

Six new data sets from the Boreal Ecosystem-Atmosphere Study (BOREAS) were released by the ORNL DAAC on October 15, 1999. The release brings the total number to 186 data sets currently available.

The newest data are related to hydrology, remote sensing, and background measurements (called "staff science"):

Matthews Global Vegetation

The ORNL DAAC has recently made the Matthews Global Vegetation Data available. The vegetation data at the ORNL DAAC are used primarily as driving variables in terrestrial biogeochemistry models.

Global Climate Data

The climate data at the ORNL DAAC are used primarily as driving variables in terrestrial biogeochemistry models. These models typically use data on temperature (min,max), precipitation, humidity (relative humidity, vapor pressure deficit, dew point), radiation (PFD in PAR, shortwave, direct/diffuse, and UV radiation, daylength), and wind velocity. Climate / meteorology data are required at hourly to monthly time scales, either point or gridded, at spatial scales ranging from regional to continental to global.
