Displayed background gamma radiation level is 9.8 μR/h (0.82 mSv/a) This is very close to the world average background radiation of 0.87 mSv/a from cosmic and terrestrial sources. Cloud chambers used by early researchers first detected cosmic rays and other background radiation. They can be used to visualize the background radiation
The European Space Agency's Planck satellite has been gathering data since its launch in 2009, slowly building up a map of the cosmic microwave background radiation -- a distant remnant of the Big ...
The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape our understanding of the cosmos.
The power spectrum of the cosmic microwave background radiation temperature anisotropy in terms of the angular scale (or multipole moment). The data shown comes from the WMAP (2006), Acbar (2004) Boomerang (2005), CBI (2004), and VSA (2004) instruments. Also shown is a theoretical model (solid line).
To monitor the background (least influenced by immediate human activities which are regionally concentrated) shortwave and longwave radiative components and their changes with the best methods currently available. To provide data for the calibration of satellite-based estimates of the surface radiative fluxes.
The Terra satellite, launched in December 1999, carried two (Flight Module 1 (FM1) and FM2) and the Aqua satellite, launched in May 2002, carried two more (FM3 and FM4). A fifth instrument (FM5) was launched on the Suomi NPP satellite in October 2011 and a sixth (FM6) on NOAA-20 in November 2017. With the failure of the PFM on TRMM and the 2005 ...
FORUM (Far-infrared Outgoing Radiation Understanding and Monitoring) is an Earth observing satellite that is scheduled to launch in 2027. [2] The FORUM mission is led by the European Space Agency (ESA) and has as its main goal the study of the Earth's radiation budget.
Terra (EOS AM-1) is a multi-national scientific research satellite operated by NASA in a Sun-synchronous orbit around the Earth.It takes simultaneous measurements of Earth's atmosphere, land, and water to understand how Earth is changing and to identify the consequences for life on Earth. [1]
