BigFoot Leaf Area Index Surfaces for North and South American Sites, 2000-2003

The BigFoot project gathered leaf area index (LAI) data for nine EOS Land Validation Sites located from Alaska to Brazil from 2000 to 2003. Each site is representative of one or two distinct biomes, including the Arctic tundra; boreal evergreen needleleaf forest; temperate cropland, grassland, evergreen needleleaf forest, and deciduous broadleaf forest; desert grassland and shrubland; and tropical evergreen broadleaf forest. LAI was measured at plots within each site for at least two years using standard direct and optical methods at each site. Direct measurement approaches included periodic area harvest for non-forest sites and application of allometric equations to tree diameter data for forest sites. LAI was also estimated indirectly using the Li-Cor LAI-2000 Plant Canopy Analyzers (Gower et al. 1999). LAI was measured three times each year at the forest sites and four to six times at other sites depending upon the phenology of LAI development for a given ecosystem. To develop LAI surfaces at any given site, the Landsat ETM+ image closest in date to maximum LAI was chosen as a reference and images from other dates radiometrically normalized to it. Each LAI surface has a grain of 25 meters and covers a 7 x 7 km extent. The data set consists of the LAI surface images in standard geotiff format, an accompanying text file which provides metadata specific to the image (such as projection, data type, class names, etc), and associated auxiliary and world files. Additional information on LAI measurements and surface development can be found on the BigFoot website at http://www.fsl.orst.edu/larse/bigfoot/ovr_mthd.html. BigFoot Project Background: Reflectance data from MODIS, the Moderate Resolution Imaging Spectrometer onboard NASA's Earth Observing System (EOS) satellite Terra (http://landval.gsfc.nasa.gov/MODIS/index.php), is used to produce several science products including land cover, leaf area index (LAI) and net primary production (NPP). The overall goal of the BigFoot Project was to provide validation of these products. To do this, BigFoot combined ground measurements, additional high resolution remote sensing data, and ecosystem process models at nine flux tower sites representing different biomes to evaluate the effects of the spatial and temporal patterns of ecosystem characteristics on MODIS products. BigFoot characterized up to a 7 x 7 km area (49 MODIS pixels) surrounding the CO2 flux towers located at each of the nine sites. We collected multi-year, in situ measurements of ecosystem structure and functional characteristics related to the terrestrial carbon cycle. Our sampling design allowed us to examine scales and spatial pattern of these properties, the inter-annual variability and validity of MODIS products, and provided for a field-based ecological characterization of the flux tower footprint. BigFoot was funded by NASA's Terrestrial Ecology Program.

IHW COMET HALLEY DIGITIZED PHOTOGRAPHIC SPECTRA V1.0

NASA's International Halley Watch (IHW) has created a Comet Halley Archive. The collection of data spans the full wavelength range as submitted by scientists to the IHW. The observations belong to one of the following Disciplines: Amateur, Astrometry, Infrared Studies, Large-Scale Phenomena, Meteor Studies, Near-Nucleus Studies, Photometry and Polarimetry, Radio Studies, and Spectroscopy and Spectrophotometry. The data collected by these nine disciplines were augmented by Spacecraft measurements. The data were submitted to IHW, but the evaluation and selection for the Archive has been the primary responsibility of the Discipline Specialist Teams for each network in cooperation with the Lead Center. The Spectroscopy and Spectrophotometry Network collected 352 files that represented the digitized spectra from plate material. In some cases, the non-Halley targets for the spectroscopic observations can be grouped according to 'laboratory' calibration, dark, bias, flatfield, sky, and photometric standards. In the first category, a large number of 'arcs' and 'lamps' were used as follows: HE-NE, TH-AR, NE-AR, CU-AR, CU-NE, Thorium, Tungsten, Quartz, and Rubidium. For the 'sky' observers used the twilight, moonlight, and blank sky. The most common 'photometric' standards were stars, but observers also included other comets (Hartley-Goode), asteroids (Ceres), reflection nebulae (R8), and emission nebulae (NGC1982, NGC7000). A list of these stellar calibration targets follows: HD 140283, HD 184711, HD89688, HD102870, HD120086, HD13974, HD219188, HD 25680, HD 19445, HD18803, HD30455, HD26912, SAO 1280, HZ15, CD-22 7696, GD 190, GC5106, GC2188, GC2192, G19113213, G 99-37, L745-46A, Feige 15, Feige 56, Landolt 98, Landolt 92, Van Beuren, RHO ORION, CHI 1 ORION, 29 PI LEO. For this data, no distinction about 'reduction' is distinguished for this process. The data cover the date range from 1985 October 17 through 1986 December 12.

GIOTTO PARTICLE IMPACT ANALYZER DUST MASS SPECTRA V1.0

The PIA data was acquired in four modes of data compression, termed mode 0 (the least compressed), and modes 1, 2, and 3, each with increasing degrees of compression. With each spectrum are a PIA assigned sequence number and event numbers, a unique ID-number, instrument settings, and the relative approach time. The PIA time is a 16-bit counter that starts with zero after switch-on. As the Spacecraft Time Signal (STS) is used to reset the internal PIA time counter, the TIM highest possible value is 48960 counts. STS-pulses are given after the transimssion of 256 formats. This results for format F1/F2 and high bitrate (46080 bps) in 5802.67 s. (: 256 formats * 64 frames * 2040 bytes * 8 bit/byte/46080 bps) The time resolution is DTIM : 1/ (138240 HZ /2**14 ) : 0.1185 s. Each STS defines the time for an event with TIM : 0. Therefore, SCET : GRT(STS) + (TIM * DTIM) - propogation delay (8:00.1 sec). where SCET : Spacecraft Event Time, GRT : Ground Reception Time.
