Summary
Description
This data set provides three data files in text format (.txt). Two files contain biomass and above-ground net primary production (ANPP) estimates for two upland meadows with contrasting soil types at the Otradnoe research station of the V.L. Komarov Botanical Institute of the Russian Academy of Sciences located on the Karelian peninsula 100-km to the north of St. Petersburg, Russia. The third file contains monthly and annual climate data recorded at the study site for the period 1968-1973. Measurements of above- and below-ground live and dead biomass were made at a sandy meadow (OTRS) from 1969 to 1972 and at a loamy meadow (OTRL) from 1969 to 1973. Additional biomass measurements were made at OTRS in June 1972 and at OTRL in May 1973. Monthly N, P, and S content of above-ground live biomass were measured 1969-1971 at OTRS.Revision Notes: Only the documentation for this data set has been modified. The data files have been checked for accuracy and are identical to those originally published in 1996.

<p>This work will establish ultra-clean chemical purification and isotopic analysis of chromium and manganese in sub-milligram-sized astromaterial samples.&nbsp; Manganese-chromium isotopic analysis can be used to determine the age of ancient (&gt;4.5 billion year old) dust and rock fragments, as well as for mapping in space and time the distribution of primordial material in the protoplanetary disk, in particular during the early accretion period of asteroids.&nbsp; This laboratory-based research will be coordinated with our microMill sampling facility and state-of-the art Triton thermal ionization mass spectrometer (TIMS).&nbsp; This work will develop the high precision analysis processes of ultra small samples of the type that will be returned by robotic and, eventually, human exploration missions to asteroids.&nbsp; We will also integrate microMill sampling, chemical purification, and TIMS analysis of small targeted regions of larger samples (e.g., core and/or rims of minerals contained in rocks returned from differentiated asteroids, the Moon, and/or possibly ancient rocks from Mars). At the completion of this multi-year project ARES scientists will have well-developed, calibrated, and fully-documented sets of: (1) low blank micro-dissolution vessels and (2) of micro-columns to efficiently purify Mn and Cr from future small returned samples, as well as an ultra-clean workspace to conduct these experiments.&nbsp; In short, we propose to have all sample procedures and laboratory spaces prepared and tested prior to any future Mission-related sample allocation.&nbsp; This work will strongly enhance the quality of science results obtained from the tiny particles expected to be returned by robotic, and eventually human, exploration missions.</p>

Summary
Description
Bathythermograph data were collected from the TANEY within a 1-mile radius of Ocean Weather Station N (3000N 14000W) and in transit. Data were collected by the United States Coast Guard from 04 June 1970 to 02 July 1970. The platform was equipped and staffed to observe weather and sea conditions. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

This product is similar to AIRX2RET. It is newest products produced using AIRS IR only because the radiometric noise in AMSU channel 4 started to increase significantly (since June 2007). The AIRS Standard Retrieval Product consists of retrieved estimates of cloud and surface properties, plus profiles of retrieved temperature, water vapor, ozone, carbon monoxide and methane. Estimates of the errors associated with these quantities will also be part of the Standard Product. The temperature profile vertical resolution is 28 levels total between 1100 mb and 0.1 mb, while moisture profile is reported at 14 atmospheric layers between 1100 mb and 50 mb. The horizontal resolution is 50 km. An AIRS granule has been set as 6 minutes of data, 30 footprints cross track by 45 lines along track. (The Shortname for this product is AIRS2RET).

Summary
Description
The Coastal Zone Color Scanner Experiment (CZCS) was the first instrument devoted to the measurement of ocean color and flown on a spacecraft. Although other instruments flown on other spacecraft had sensed ocean color, their spectral bands, spatial resolution and dynamic range were optimized for land or meteorological use and had limited sensitivity in this area, whereas in CZCS, every parameter was optimized for use over water to the exclusion of any other type of sensing. CZCS had six spectral bands, four of which were used primarily for ocean color. These were of a 20 nanometer bandwidth centered at 443, 520, 550, and 670 nm. Band 5 had a 100 nm bandwidth centered at 750 nm and a dynamic range more suited to land. Band 6 operated in the 10.5 to 12.5 micrometer region and sensed emitted thermal radiance for derivation of equivalent black body temperature. (This thermal band failed within the first year of the mission, and so was not used in the global processing effort.) Bands 1-4 were preset to view water only and saturated when the IFOV was over most types of land surfaces, or clouds.

MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

The 2006-07 Integrated Postsecondary Education Data System (IPEDS 2006-07) was a study that was part of the Integrated Postsecondary Education Data System (IPEDS) program; program data is available since 1980 at . IPEDS 2006-07 (http://nces.ed.gov/ipeds/) was a cross-sectional survey designed to collect basic data from all postsecondary institutions in the United States and the other jurisdictions. Key statistics produced from IPEDS 2006-07 allowed the National Center for Education Statistics (NCES) to describe the size of one of the nation's largest enterprises--postsecondary education-- in terms of students enrolled, degrees and other awards earned, dollars expended, and staff employed. All Title IV institutions were required to respond to IPEDS (see Section 490 of the Higher Education Amendments of 1992 [P.L. 102-325; 20 U.S.C. � 1070 et seq.]). IPEDS allowed other, non-Title IV institutions to participate on a voluntary basis, but only about 200 elected to respond.

The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The purpose of this file is to provide the geography for the 2010 Census Blocks along with their 2010 housing unit count and population. Census Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. Blocks are the smallest geographic areas for which the Census Bureau publishes data from the decennial census. A block may consist of one or more faces.
