On the Atmospheric Transport and Deposition of the Cosmogenic Radionuclides (10Be): A Review

Meteoric cosmogenic Beryllium-10 adsorbed to river sediment and soil: Applications for Earth-surface dynamics

“…To evaluate these competing influences of 10 Be production and delivery quantitatively, we rely on the recent work of Field et al (2006) who used the Goddard Institute for Space Studies ModelE (GISS) general circulation model (GCM) and Heikkilä (2007) who used the European Centre for MediumRange Weather Forecasts-Hamburg Model 5 (ECHAM5) GCM in combination with Masarik and Beer's (1999) production functions. These authors evaluated the effect of specific climate controls over the 10 Be concentration signals in ice cores.…”

“…Such models are necessary because processes that affect the distribution of 10 Be in the troposphere, such as changes in stratosphere-troposphere exchange or aerosol scavenging efficiency may change with changing climate over the globe. Figure 3 shows a mean of Heikkilä (2007) and Field et al (2006) flux results, but adapted for the long-term solar modulation factor (700 MeV) and long-term average geomagnetic field strength (M=0.75). Long-term geomagnetic field values for Heikkilä (2007) were recalculated from those published to show the long-term geomagnetic field by latitude.…”

We used Figure 5 of Field et al (2006) for this conversion.…”

“…However, changes in Earth's carbon reservoirs are difficult to assess (Köhler et al, 2006). 10 Be in midlatitude regions is nearly exclusively scavenged from the atmosphere by precipitation (Heikkilä et al, 2013). Varying atmospheric circulation and scavenging during the about 1 month long tropospheric residence time (about 1-year stratospheric residence time) result in spatially nonuniform 10 Be deposition patterns (Aldahan et al, 2008;Raisbeck et al, 1981).…”
