10 Be measured in a GRIP snow pit and modeled using the ECHAM5-HAM general circulation model
International audience Be measured in a Greenland Ice Core Project (GRIP) snow pit (1986-1990) with a seasonal resolution is compared with the ECHAM5-HAM GCM run. The mean modeled 10 Be concentration in ice (1.0Á10 4 atoms/g) agrees well with the measured value (1.2Á10 4 atoms/g). The measured 10 Be...
