1. 1. Solar variability over the Holocene period : disentangling geomagnetic and solar influences on a new continuous 10Be record from Little Dome C, Antarctica

   Författare :Hoang Long Nguyen; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ice core; cosmogenic radionuclide; 10Be; 14C; solar activity; paleomagnetism; ; Holocene;

   Sammanfattning : Reliable information on solar activity over the Holocene period is important to predict the Sun in the future and to understand the mechanism behind the Sun-climate linkage. Presently, there are discrepancies in the proxy data of solar activity due to reasons that are not yet understood. LÄS MER

3. 2. Disentangling production and climate signals from high-resolution Beryllium records: implications for solar and geomagnetic reconstructions

   Författare :Minjie Zheng; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solar Activity; 10Be; 7Be; ice cores; tropopause; climate; cosmogenic radionuclides; geomagnetic reconstructions; multi-linear regression;

   Sammanfattning : The sun is the most important energy source for the Earth’s climate system, however, influences of solar variations on climate are not fully understood. Studying past solar activity can improve our understanding of what role the sun plays in Earth’s climate. LÄS MER

4. 3. Cosmogenic radionuclides in environmental archives – A paleo-perspective on space climate and a synchronizing tool for climate records

   Författare :Florian Mekhaldi; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Comogenic radionuclides; 10Be; 36Cl; Solar energetic particles; Solar storms; Paleoclimate; Time-scales; Solar activity;

   Sammanfattning : The Sun is the primary source for Earth’s climate system. Its fluctuations in irradiance are also known to have an impact on climate. In addition, changes in solar activity modulate the atmospheric production rates of cosmogenic radionuclides (e.g. LÄS MER

5. 4. Extreme solar particle storms and links to solar activity inferred from cosmogenic radionuclides in ice cores

   Författare :Chiara Paleari; MERGE: ModElling the Regional and Global Earth system; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ice cores; cosmogenic radionuclides; Solar storms; 10Be; 36Cl; Solar energetic particles;

   Sammanfattning : During solar storms, large amounts of solar energetic particles (SEP) are accelerated into the interplanetary medium and sometimes hit Earth. These events, known as SEP events, can have harmful impacts on our modern society by affecting spacecrafts and potentially astronauts in space. LÄS MER

7. 5. Solar Activity Changes at the End of the Last Ice Age - Influences on Climate and Applications for Dating

   Författare :Florian Adolphi; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solar Activity; 10Be; 14C; radiocarbon calibration; time scale; geochronology; paleoclimate; ice cores; tree rings; IntCal; cosmogenic radionuclides;

   Sammanfattning : Throughout its history Earth experienced a variety of natural climate changes. By investigating their spatial and temporal evolution we can increase the understanding of the mechanisms and dynamics underlying natural climate change and improve our general comprehension of the climate system.
