Solar irradiance during the last 1200 years based on cosmogenic nuclides
Based on a quantitative study of the common fluctuations of 14C and 10Be production rates, we have derived a time series of the solar magnetic variability over the last 1200 years. This record is converted into irradiance variations by linear scaling based on previous studies of sun-like stars and of the sun’s behavior over the last few centuries. The new solar irradiance record exhibits low va...

متن کاملAmerica`s Strategies against IR during the Last Forty Years
The Islamic Revolution, as the greatest historical evolution of contemporary times, has caused America`s interests face many challenges. Understanding the tools and strategies used by the United States against the Islamic Republic of Iran helps us to better understand and confront the country. In this regard, using the theory of invasive realism, American strategies against the Islamic Republic...
متن کاملCosmogenic nuclides, topography, and the spatial variation of soil depth
If the rate of bedrock conversion to a mobile layer of soil depends on the local thickness of soil, then hillslopes on uniform bedrock in a landscape approaching dynamic equilibrium should be mantled by a uniform thickness of soil. Conversely, if the depth of soil varies across an actively eroding landscape, then rates of soil production will also vary and, consequently the landscape will not b...
متن کاملTotal solar irradiance during the Holocene
For the first time a record of total solar irradiance covering 9300 years is presented, which covers almost the entire Holocene. This reconstruction is based on a recently observationally derived relationship between total solar irradiance and the open solar magnetic field. Here we show that the open solar magnetic field can be obtained from the cosmogenic radionuclide Be measured in ice cores....
