Abstract |
We submit three candidate models following the call for IGRF-11. We apply a simple modeling approach in spherical harmonics based on a quadratic Taylor expansion for the internal field time variations. We use the Dst magnetic index as a proxy for the external field variations. In order to compensate for the limitations incurred by such a conventional approach, we focus on the optimal selection of satellite data in space and time. We also show that some a priori knowledge about the core field state helps us to avoid the pitfall encountered in the case of rapid changes of core field accelerations. Indeed, various acceleration events of relevance for the IGRF 11th occurred between 2003 and 2010, one of them being a geomagnetic jerk. They could entail disagreements between IGRF candidate models for the secular variation (SV) if data prior to 2008 are used. Our SV and main field (MF) candidate models have a root mean square uncertainty less than 6 nT/yr and 8nT, respectively, with respect to the modeled magnetic field contributions. These values correspond to the intrinsic error associated with truncating SV and MF models to spherical harmonic degree 8 and 13, respectively, as requested for IGRF models. |

Abstract |
Abstract: Half-daily high volume aerosol particles samples have been collected onto Õlesund, Svalbard, from April +.th to May 1th cellulose and glass fiber filters at Ny-A ,**., in the framework of CHIMERPOL II program. The filters have been analyzed for ,+*Pb (,,.- y) and 1Be (/- d) by semiconductor gamma spectrometry. The median concentration values were 1* mBq m?- STP (2?,0. mBq m?- STP) for ,+*Pb, and .*. mBq m?- STP (-/?2,. mBq m?- STP) for 1Be respectively. The 1Be and ,+*Pb activity concentrations measured are relatively “low” compared to those measured in Svalbard and in other Arctic sites for the same period time (April?May) during previous studies.
The ,+*Pb atmospheric concentration and atmospheric pressure are positively cor-
related, which may indicate that the ,+*Pb atmospheric concentration increase as a
function of air mass exchange over the Svalbard region. The results of 1Be and ozone concentrations show also the absence of direct 1Be stratospheric injections during our sampling campaign, in the low troposheric air masses. The performed backward trajectory analysis showed that collected aerosols and associated radionuclides concentrations were associated to three di#erent air masses, originating from Atlantic ocean, Artic ocean and Barents Sea, and continental areas (North Finland?Russia) respectively. |
