OMNI Combined Heliopheric Observations (COHO), Merged Magnetic Field, Plasma and Ephermeris, Definitive Hourly Data

Hourly Averaged Definitive Multispacecraft Interplanetary ParametersData. The Heliographic Inertial, HGI, Coordinates are Sun-Centered and inertially fixed with respect to an X-Axis directed along the Intersection Line of the Ecliptic and Solar Equatorial Planes. The Solar Equatorial Plane is inclined at 7.25° from the Ecliptic. This Direction was towards Ecliptic Longitude of 74.367° on 1 January 1900 at 1200 UT but because of Precession of the Celestial Equator, this Longitude increases by 1.4° per Century. The Z-Axis is directed Perpendicular and Northward from the Solar Equator, and the Y-Axis completes the Right-Handed Set. This System differs from usual Heliographic Coordinates, e.g. Carrington Longitudes, which are fixed in the Frame of the Rotating Sun. The RTN System is fixed at a Spacecraft or a Planet. The R-Axis is directed radially away from the Sun, the T-Axis is the Cross Product of the Solar Rotation Axis and the R-Axis, and the N-Axis is the Cross Product of the R-Axis and T-Axis. At 0° Heliographic Latitude when the Spacecraft is in the Solar Equatorial Plane, the N-Axis and Solar Rotation Axis are Parallel. Latitude and Longitude Angles of Solar Wind Plasma Flow are generally measured from the Radius Vector away from the Sun. In all cases, Latitude Angles are Positive for North-Going Flow. The Flow Longitude Angles have been treated differently for the Near-Earth Data, i.e. the OMNI, and for the Deep Space Data. The Flow is Positive for the Near-Earth Data when coming from the Right Side of the Sun as viewed from the Earth, i.e. flowing toward +Y from -X GSE or Opposite to the Direction of Planetary Motion. On the other hand, the Flow Longitudes for the Deep Space Spacecraft use the opposite Sign Convection, i.e. Positive for Flow in the +T Direction in the RTN System.

USGS Group on Earth Observations (GEO) Global Agricultural Monitoring (GLAM) Algeria

The objective of GEO is to fulfil a vision of a world where decisions and actions are informed by coordinated, comprehensive and sustained Earth Observation (EO). This is being pursued mainly through the added value of co-ordinating existing institutions, organised communities, space agencies, in-situ monitoring agencies, scientific institutions, research centres, universities, modelling centres, technology developers and other groups that deal with one or more aspects of EO. To reach this overarching goal, GEO focuses on capacity development in three dimensions: infrastructure, individuals and institutions. In the field of agriculture, the general goal is to promote the utilization of Earth observations for advancing sustainable agriculture, aquaculture and fisheries. Key issues include early warning, risk assessment, food security, market efficiency and combating desertification.

Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO)

Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (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 formation with five other satellites in the international 'A-Train' (PDF) constellation for coincident Earth observations. The CALIPSO satellite comprises three instruments, the Cloud-Aerosol LIdar with Orthogonal Polarization (CALIOP), the Imaging Infrared Radiometer (IIR), and the Wide Field Camera (WFC). CALIPSO is a joint satellite mission between NASA and the French Agency, CNES.

This archive contains raw observations of the 2009-10-09 impact of the LCROSS spacecraft on the moon by the CCD47 camera on the MMT Observatory 6.5m telescope. The archive consists of uncalibrated FITS images of the event. This is one of several data sets of Earth-based observations of the impact.

USGS Global Forest Observations Initiative (GFOI) Costa Rica

The Global Forest Observations Initiative (GFOI) is an initiative of the inter-governmental Group on Earth Observations (GEO) that aims to: foster the sustained availability of observations for national forest monitoring systems; support governments that are establishing national systems by providing a platform for coordinating observations, providing assistance and guidance on utilizing observations, developing accepted methods and protocols, and promoting ongoing research and development; and work with national governments that report into international forest assessments (such as the global Forest Resources Assessment (FRA) of the Food and Agriculture Organization, FAO) and the national greenhouse gas inventories reported to the UN Framework Convention on Climate Change (UNFCCC) using methods of the Intergovernmental Panel on Climate Change (IPCC).

IHW COMET HALLEY POLARIMETRIC OBSERVATIONS 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 Photometry and Polarimetry Network collected 884 polarimetric observations for the Polarimetry Subnetwork. The majority of these observations (752) are expressed as 'percent polarization'. These data span the dates from 1985 September 13 through 1986 May 17.
