BOREAS Oct. 15 Release

Submitted by ORNL DAAC Staff on 1999-10-15

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"):

  • BOREAS HYD-09 Hourly and Daily Radar Rainfall Maps for the Southern Study Area - Radar data that can be used to construct hourly and daily rainfall maps.

  • BOREAS RSS-02 Extracted Reflectance Factors Derived from ASAS Imagery - Reflectance factors for small homogeneous areas around ground measurement sites, derived from remote sensing imagery.

  • BOREAS Daedalus TMS Level-0 Imagery Digital Counts in BIL Format - Remotely sensed images showing radiant energy in the visible, near-infrared, and thermal-infrared wavelengths. May be useful in constructing land cover maps and estimating vegetation biophysical parameters such as absorbed photosynthetically active radiation and leaf area index.

  • BOREAS Landsat TM Level-3a Imagery Scaled at Sensor Radiance in BSQ Format - Remotely sensed images showing radiant energy in the visible, near-infrared, and thermal-infrared wavelengths. May be useful in constructing land cover maps and estimating vegetation biophysical parameters such as absorbed photosynthetically active radiation and leaf area index [this is considered proprietary data; contact the ORNL DAAC to determine need to know].

  • BOREAS Level-0 AOCI Imagery Digital Counts in BIL Format - Remotely sensed images indicating chlorophyll content and turbidity of aquatic areas.

  • BOREAS Level-0 TIMS Imagery Digital Counts in BIL Format - Remotely sensed images from a thermal infrared multispectral scanner, useful for geologic mapping.

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.
