BOREAS Level-4b AVHRR-LAC Ten-Day Composite Images: At-Sensor Radiance

The BOREAS Staff Science Satellite Data Acquisition Program focused on providing the research teams with the remotely sensed satellite data products they needed to compare and spatially extend point results. MRSC and BORIS personnel acquired, processed, and archived data from the AVHRR instruments on the NOAA-11 and -14 satellites. The AVHRR data were acquired by CCRS and were provided to BORIS for use by BOREAS researchers. These AVHRR level-4b data are gridded, 10-day composites of at-sensor radiance values produced from sets of single-day images. Temporally, the 10-day compositing periods begin 11-Apr-1994 and end 10-Sep-1994. Spatially, the data cover the entire BOREAS region. The data are stored in binary image format files. Companion files include example thumbnail images that may be viewed and the image data files downloaded using a convenient viewer utility.

BOREAS Landsat TM Level-3p Imagery: Geocoded and Scaled At-Sensor Radiance

For BOREAS, the level-3p Landsat TM data were used to supplement the level-3s Landsat TM products. Along with the other remotely sensed images, the Landsat TM images were collected in order to provide spatially extensive information over the primary study areas. This information includes radiant energy, detailed land cover, and biophysical parameter maps such as FPAR and LAI. Although very similar to the level-3s Landsat TM products, the level-3p images were processed with ground control information which improved the accuracy of the geographic coordinates provided. Geographically, the level-3p images cover the BOREAS NSA and SSA. Temporally, the four images cover the period of 20-Aug-1988 to 07-Jun-1994. Except for the 07-Jun-1994 image which contains 7 bands, the other three only contain 3 bands. Companion files include (1)an image inventory listing to inform users of the images that are available and (2) example thumbnail images that may be viewed using a convenient viewer utility.

BOREAS RSS-07 LAI, Gap Fraction, and FPAR Data

The BOREAS RSS-07 team collected various data sets to develop and validate an algorithm to allow the retrieval of the spatial distribution of LAI from remotely sensed images. Ground measurements of LAI and FPAR absorbed by the plant canopy were made using the LAI-2000 and TRAC optical instruments during focused periods from 09-AUG-1993 to 19-SEP-1994. The measurements were intensive at the NSA and SSA tower sites, but were made just once or twice at auxiliary sites.

BOREAS RSS-08 BIOME-BGC Model Simulations at Tower Flux Sites in 1994

BIOME-BGC is a general ecosystem process model designed to simulate biogeochemical and hydrologic processes across multiple scales (Running and Hunt, 1993). In this investigation, BIOME-BGC was used to estimate daily water and carbon budgets for the BOREAS tower flux sites for 1994. Carbon variables estimated by the model include gross primary production (i.e., net photosynthesis), maintenance and heterotrophic respiration, net primary production, and net ecosystem carbon exchange. Hydrologic variables estimated by the model include snowcover, evaporation, transpiration, evapotranspiration, soil moisture, and outflow. The information provided by the investigation includes input initialization and model output files for various sites in tabular ASCII format.

CRRES Aerospace Agency Tape data

This data set includes files from the "Aerospace Agency Tapes" compiled by the Aerospace Corporation for selected experiments from the CRRES raw telemetry data stream provided through three digital processing units (DPUs) supporting Aerospace-related sensors. These sensors are as follows: the Magnetospheric Ion Composition Spectrometer (MICS), Heavy Ion Telescope (HIT), Low Energy Magnetospheric Ion Composition Sensor (LOMICS), the Medium Electrons A spectrometer (MEA), the Electron and Proton Wide-Angle Spectrometer (EPAS), the Relativistic Proton Detector (RPD), the Proton Switches (PS1, PS2), and a 4-band photometer for chemical release measurements. These instruments were turned on during Orbit 6, off at Orbit 365, and on again at Orbit 416 through the end of mission at Orbit 1067. When another complement of instruments called LASSII were periodically turned on for 20-minute or one-hour intervals near perigee for ionospheric measurements, the RADSAT (magnetospheric) complement, including the Aerospace instruments, were turned off. Spacecraft ephemeris, attitude, and magnetic field data are also provided. For each ten-hour orbit of CRRES includes a set of five files is provided from the original Agency tapes: header, ephemeris, attitude, magnetic field, and the Aerospace instrument raw data file. The magnetic field files are not those provided on the original Agency tapes but include field vector components in magnetometer sensor coordinates as computed from software and final calibration coefficients provided by the CRRES magnetometer team. The instrument data are provided at raw telemetry level in complex form, and users are requested to contact the responsible experimenters concerning correct usage. The binary data are encoded 32-bit words for reading on IBM-compatible PC's; byte order may need to be reversed for usage of other systems (e.g., VMS). FORTRAN source codes with PC-executables are provided to extract selected parameters from the spacecraft and instrument file types. References to documentation for the Aerospace instruments are listed in the main readme file.

BOREAS NS001 TMS Level-2 Images: Reflectance and Temperature in BSQ Format

For BOREAS, the NS001 TMS images, along with the other remotely sensed data, were collected to provide spatially extensive information over the primary study areas. This information includes detailed land cover and biophysical parameter maps such as fPAR and LAI. Collection of the NS001 images occurred over the study areas during the 1994 field campaigns.

The data are not geographically/geometrically corrected; however, files of relative X and Y coordinates for each image pixel were derived by using the C130 INS data in an NS001 scan model. The data are provided in binary image format files. Note also that the top portion of the ASCII header file in each Level-2 NS001 image product indicates that the band 8 data are 'Scaled Reflectance' when in fact they are 'Scaled Temperatures.'
