BOREAS HYD-03 Snow Water Equivalent: 1996

The BOREAS HYD-03 team collected several data sets related to the hydrology of forested areas. This data set contains measurements of snow depth, snow density in 3-cm intervals, an integrated snow pack density and snow water equivalent (SWE), and snow pack physical properties from snow pit evaluation taken in 1994 and 1996. The data were collected from several sites in both the SSA and the NSA. A variety of standard tools were used to measure the snowpack properties, including a meter stick (snow depth), a 100 cc snow density cutter, a dial stem thermometer and the Canadian snow sampler as used by HYD-04 to obtain a snow pack-integrated measure of SWE. This study was undertaken to predict spatial distributions of snow properties important to the hydrology, remote sensing signatures, and the transmissivity of gases through the snow.

MESSENGER H XRS REDUCED DATA RECORD (RDR) MAPS V1.0

Abstract : This data set consists of the MESSENGER XRS reduced data record observations, also known as RDRs, which are derived from the calibrated data records, CDRs. Each XRS observation results in four X-ray spectra. When an X-ray interacts with one of the four detectors, a charge or voltage pulse is generated. This signal is converted into one of 2^8 (256) channels, which are correlated to energy. Over a commanded integration time period a histogram of counts as a function of energy (channel number) is recorded. The EDRs are the number of events in each channel of the four detectors accumulated over the integration period. Channels above or below the useful energy range of the detectors are not transmitted. The result is three 244-channel GPC histograms and one 231-channel solar monitor histogram, each of which is designated as a single X-ray spectrum. Each observation is calibrated and processed into the CDR data set and then further processed to produce a map of elemental ratios, the maps of which compose the RDR data set.

BOREAS Landsat TM Level-3b Imagery: At-Sensor Radiance in BSQ Format

For BOREAS, the level-3b Landsat TM data, along with the other remotely sensed 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 in content to the level-3a Landsat TM products, the level-3b images were created to provide users with a directly usable at-sensor radiance image. Geographically, the level-3b images cover the BOREAS NSA and SSA. Temporally, the images cover the period of 22-Jun-1984 to 30-Jul-1996. 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 HYD-08 1994 Gravimetric Moss Moisture Data

The BOREAS HYD-08 team made measurements of surface hydrological processes that were collected at the NSA OBS Tower Flux site in 1994 and at Joey Lake, Manitoba, to support their research into point hydrological processes and the spatial variation of these processes. The data collected may be useful in characterizing canopy interception, drip, throughfall, moss interception, drainage, evaporation, and capacity during the growing season at daily temporal resolution. This particular data set contains the gravimetric moss moisture measurements from June to September 1994. A nested spatial sampling plan was implemented to support research into spatial variations of the measured hydrological processes and ultimately the impact of these variations on modeled carbon and water budgets.

The Level 1B data product is written in HDF. CALIPSO was launched on April 28, 2006 to study the impact of clouds and aerosols on the Earth's radiation budget and climate. It flies in the international A-Train constellation for coincident Earth observations. The CALIPSO satellite is comprised of three instruments, the Cloud-Aerosol LIdar with Orthogonal Polarization (CALIOP), IIR, and the Wide Field Camera (WFC).

LOWELL OBSERVATORY COMETARY DATABASE

The database presented here is comprised entirely of observations made utilizing conventional photoelectric photometers and narrowband filters isolating 5 emission species (OH, NH, CN, C3 and C2) and continua. This work was initiated by A'Hearn and Millis in 1976 and includes 2020 observations of 85 comets obtained over 429 nights through the end of 1992. The total number of observations, however, is not evenly distributed over the 85 comets. The median number of observations for a comet is 6, with only a single observation obtained for 14 comets while there were 820 observations of P/Halley. The majority of observations were obtained at either Lowell Observatory or Perth Observatory, however four other observatories were used including an extensive campaign on comet P/Halley from the Cerro Tololo Interamerican Observatory (CTIO). In this archive, results for a subset of 68 comets are presented while the results for P/Halley from this study are archived in the IHW archive.
