History of Newton's Papers (1727-1872) | Newton Project At his death on 20 March 1727, Isaac Newton left papers relating to all areas of the intellectual pursuits he had followed since arriving at Trinity College, Cambridge, in the summer of 1661. His friend, relative by marriage (to Newton's half-niece Catherine Barton) and successor at the Mint, John Conduitt, posted a bond for Newton's debts and claimed entitlement to this material, Newton having died intestate. As is evident from a number of manuscripts adorned with Conduitt's notes and corrections -- for example the manuscript of 'An historical account of two notable corruptions of Scripture in a Letter to a Friend' (now New College, Oxford, Ms. 361.4) -- he took a serious scholarly interest in the papers he had acquired, although this was also partly directed towards the possibility of their publication.

Loading parameters... Giovanni is a Web application developed by the GES DISC to provide a simple, intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data, particularly from satellites, without having to download the data. Giovanni consists of several portals tailored to meet the needs of different Earth science research communities.
GEOSTATIONARY SATELLITE SERVER Encyclopedia of Earth Download data by country | DIVA-GIS Select and download free geographic (GIS) data for any country in the world Sources Formats The files have been compressed and grouped in ZIP files. Vector data are stored as ESRI shapefiles Grid (raster) data are stored as DIVA gridfiles Each "shapefile" consist of at least three actual files. Gridfiles are used in DIVA-GIS. A gridfile with "country mask" indicates that the areas outside the selected country are masked out. A DBF (dBase file) is a dbase format database table. Resolution The resolution is the size of each grid cell expressed as the length of one side of one (square) cell.
Extreme Weather 2011 A year for the record books From extreme drought, heat waves and floods to unprecedented tornado outbreaks, hurricanes, wildfires and winter storms, a record 14 weather and climate disasters in 2011 each caused $1 billion or more in damages — and most regrettably, loss of human lives and property. NOAA's National Weather Service has redoubled its efforts to create a "Weather-Ready Nation", where vulnerable communities are better prepared for extreme weather and other natural disasters. NOAA forecasts, advisories, watches, warnings and community-based preparedness programs have been and will continue play an even greater role in enhancing the economy and saving lives. A Weather-Ready Nation is one in which businesses, governments and the public are armed with accurate forecasts and other critical information on which to make smart decisions to protect life and property when severe weather threatens.

OceanColor Home Page Spectral Hourglass Wizard (Using ENVI) | Exelis VIS Docs Center Use the Spectral Hourglass Wizard to guide you step-by-step through the ENVI hourglass processing flow to find and map image spectral endmembers from hyperspectral or multispectral data. The Wizard displays detailed instructions and useful information for each function. From the Toolbox, select Spectral > Spectral Unmixing > Spectral Hourglass Wizard to start the workflow. The hourglass processing flow uses the spectrally over-determined nature of hyperspectral data to find the most spectrally pure, or spectrally unique, pixels (called endmembers) within the dataset and to map their locations and sub-pixel abundances. The name of the corresponding ENVI function appears at the top of the panel during each step. After starting the Spectral Hourglass Wizard, refer to the following sections for help:

AVHRR NDVI3g 30+ Years of LAI3g and FPAR3g Data Sets We are providing you free access to a 30+ year long global data sets of vegetation leaf area index (LAI3g) and fraction vegetation absorbed photosynthetically active radiation (FPAR3g). These data sets were derived from the third generation GIMMS NDVI3g data set (hence the suffix "3g"). The data sets are at 1/12 degree resolution, 15-day composites (2 per month) and span the period July 1981 to December 2011. Please note the following: (1) If you wish to submit an article to the special dedicated to NDVI3g/LAI3g/FPAR3g of the open source journal "Remote Sensing" you are welcome. (2) The article describing the LAI3g/FPAR3g by Zhu et al. can downloaded from the Special Issue (3) To obtain the data sets, please contact Ranga B.
