Geostationary Earth Radiation Budget
The Geostationary Earth Radiation Budget (GERB) is an instrument aboard EUMETSAT's Meteosat Second Generation geostationary satellites designed to make accurate measurements of the Earth radiation budget. It was produced by a European consortium consisting of the United Kingdom, Belgium and Italy. The first, known as GERB 2, was launched on 28 August 2002 on an Ariane 5 rocket. The second, GERB 1, was launched on 21 December 2005, and the third, GERB3, on 5 July 2012. The last GERB 4 device was launched 14 July 2015. The first launched GERB 2 on MSG 1 is currently situated over the Indian Ocean at 41.5°E, while GERBs 1 and 3 on MSG 2 and 3 are still located over the standard Africa EUMETSAT position. GERB 4 on MSG is yet to become operational. Scientific motivations and objectives The unprecedented rate of atmospheric increase occurring since the industrial revolution due to human activity is of much concern to scientists as it has occurred an order of magnitude faster than pla ...

EUMETSAT
The European Organization for the Exploitation of Meteorological Satellites (EUMETSAT) is an intergovernmental organisation created through an international convention agreed by a current total of 30 European Member States. EUMETSAT's primary objective is to establish, maintain and exploit European systems of operational meteorological satellites. EUMETSAT is responsible for the launch and operation of the satellites and for delivering satellite data to end-users as well as contributing to the operational monitoring of climate and the detection of global climate changes. The activities of EUMETSAT contribute to a global meteorological satellite observing system coordinated with other space-faring nations. Satellite observations are an essential input to numerical weather prediction systems and also assist the human forecaster in the diagnosis of potentially hazardous weather developments. Of growing importance is the capacity of weather satellites to gather long-term measurem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moon Gerb
The Moon is Earth's only natural satellite. It is the fifth largest satellite in the Solar System and the largest and most massive relative to its parent planet, with a diameter about one-quarter that of Earth (comparable to the width of Australia). The Moon is a planetary-mass object with a differentiated rocky body, making it a satellite planet under the geophysical definitions of the term and larger than all known dwarf planets of the Solar System. It lacks any significant atmosphere, hydrosphere, or magnetic field. Its surface gravity is about one-sixth of Earth's at , with Jupiter's moon Io being the only satellite in the Solar System known to have a higher surface gravity and density. The Moon orbits Earth at an average distance of , or about 30 times Earth's diameter. Its gravitational influence is the main driver of Earth's tides and very slowly lengthens Earth's day. The Moon's orbit around Earth has a sidereal period of 27.3 days. During each synodic perio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerb2z
GERB ( bg, ГЕРБ, translation=coat of arms, acronym for Citizens for European Development of Bulgaria) is a conservative, populist political party which was the ruling party of Bulgaria between 2009 and 2021. History GERB is headed by former Prime Minister of Bulgaria Boyko Borisov, the former mayor of Sofia, former member of the National Movement Simeon II and former personal guard of Todor Zhivkov in the 1990s. The establishment of the party followed the creation of a non-profit organization with the acronym (in Bulgarian) GERB — ''Citizens for European Development of Bulgaria'', earlier the same year. In early January 2007, and early February 2007, the party came second in public polls on party support with around 14%, trailing the Bulgarian Socialist Party which had around 25%. Its stated priorities are fighting crime and corruption, preserving family as the cornerstone of society and achieving energy independence. GERB won the 2009 European Parliament ele ...

Rutherford Appleton Laboratory
The Rutherford Appleton Laboratory (RAL) is one of the national scientific research laboratories in the UK operated by the Science and Technology Facilities Council (STFC). It began as the Rutherford High Energy Laboratory, merged with the Atlas Computer Laboratory in 1975 to create the Rutherford Lab; then in 1979 with the Appleton Laboratory to form the current laboratory. It is located on the Harwell Science and Innovation Campus at Chilton near Didcot in Oxfordshire, United Kingdom. It has a staff of approximately 1,200 people who support the work of over 10,000 scientists and engineers, chiefly from the university research community. The laboratory's programme is designed to deliver trained manpower and economic growth for the UK as the result of achievements in science.

Clouds And The Earth's Radiant Energy System
Clouds and the Earth's Radiant Energy System (CERES) is NASA climatological experiment from Earth orbit. The CERES are scientific satellite instruments, part of the NASA's Earth Observing System (EOS), designed to measure both solar-reflected and Earth-emitted radiation from the top of the atmosphere (TOA) to the Earth's surface. Cloud properties are determined using simultaneous measurements by other EOS instruments such as the Moderate Resolution Imaging Spectroradiometer (MODIS). Results from the CERES and other NASA missions, such as the Earth Radiation Budget Experiment (ERBE), could enable nearer to real-time tracking of Earth's energy imbalance and better understanding of the role of clouds in global climate change. Scientific goals CERES experiment has four main objectives: * Continuation of the ERBE record of radiative fluxes at the top of the atmosphere (TOA) for climate change analysis. * Doubling the accuracy of estimates of radiative fluxes at TOA and the Ear ...

Cloud Forcing
In meteorology, cloud forcing, cloud radiative forcing (CRF) or cloud radiative effect (CRE) is the difference between the radiation budget components for average cloud conditions and cloud-free conditions. Much of the interest in cloud forcing relates to its role as a feedback process in the present period of global warming. Measuring cloud forcing The following equation calculates this change in the radiation budget at the top of the atmosphere : \Delta R_ = R_ - R_ The net cloud radiative effect can be decomposed into its longwave and shortwave components. This is because net radiation is absorbed solar minus the outgoing longwave radiation shown by the following equations : \Delta R_ = \Delta Q_ - \Delta OLR The first term on the right is the shortwave cloud effect (''Q''abs ) and the second is the longwave effect (OLR). The shortwave cloud effect is calculated by the following equation : \Delta Q_ = (S_o/4) \cdot (1 - \alpha_) - (S_o/4) \cdot (1 - \alpha_) Whe ...

Green House Effect
The greenhouse effect is a process that occurs when energy from a planet's host star goes through the planet's atmosphere and heats the planet's surface, but greenhouse gases in the atmosphere prevent some of the heat from returning directly to space, resulting in a warmer planet. Earth's natural greenhouse effect makes life as we know it possible and carbon dioxide plays a significant role in providing for the relatively high temperature on Earth. The greenhouse effect is a process by which thermal radiation from a planetary atmosphere warms the planet's surface beyond the temperature it would have in the absence of its atmosphere.A concise description of the greenhouse effect is given in the ''Intergovernmental Panel on Climate Change Fourth Assessment Report,'' "What is the Greenhouse Effect?FAQ 1.3 – AR4 WGI Chapter 1: Historical Overview of Climate Change Science, IPCC Fourth Assessment Report, Chapter 1, p. 115: "To balance the absorbed incoming [solar] energy, the Eart ...
