Analysis of the influence of solar activity and atmospheric factors on Be-7 air concentration by seasonal-trend decomposition

Bas Cerdá, María del Carmen; Ortiz Moragón, Josefina; Ballesteros Pascual, Luisa; Martorell Alsina, Sebastián Salvador (Elsevier, 2016-11)

7Be air concentrations were measured at the Universitat Politecnica de Valencia campus (in the east of Spain) during the period 2007e2014. The mean values of monthly 7Be concentrations ranged from 2.65 to 8.11 mBq/m3, ...
Evaluation of a multiple linear regression model and SARIMA model in forecasting 7Be air concentrations

Bas Cerdá, María del Carmen; Ortiz Moragón, Josefina; Ballesteros Pascual, Luisa; Martorell Alsina, Sebastián Salvador (Elsevier, 2017-06-01)

[EN] Forecasting the 7Be air concentration is a target value in analyzing fluctuations that could reveal important information on the motions of atmospheric air masses. In this study we first propose a Seasonal Autoregressive ...
Forecasting 7BE concentrations in surface air using time series analysis

Bas Cerdá, María del Carmen; Ortiz Moragón, Josefina; Ballesteros Pascual, Luisa; Martorell Alsina, Sebastián Salvador (Elsevier, 2017-02-14)

[EN] 7Be is a cosmogenic radionuclide widely used as an atmospheric tracer, whose evaluation and forecasting can provide valuable information on changes in the atmospheric behavior. In this study, measurements of 7Be ...
