Description du jeu de données | |||
Résumé | Three-dimensional air mass back-trajectories calculated using the NOAA HYbrid Single-Particle Lagrangian Integrated Trajectory Model (HYSPLIT; Draxler and Rolph, 2015). The model uses the Weather and Research Forecasting (WRF 3.7, Skamarock et al., 2008) simulations at 50, 9 and a nested simulation at 3 km of horizontal resolution. The global meteorological analyses from the National Centers for Environmental Prediction (NCEP) with the GlobalForecast System (GFS) products are used to nudge WRF hourly with pressure, temperature, humidity and wind. To preserve large scale circulations and small scale variability, the ’spectral nudging’ technique was applied (Von Storch et al., 2000). Data are provided as daily ascii files and images in png format | ||

Instrument environment | Henties Bay (22°S, 14°05’E; Namibia) is is a small town in an arid environment with no vegetation, no industrial activity and very little traffic. The site on the University campus, is located on the coast approximately 20 m from the shore line. To the east are the Namibian Gravel Plains, at 3 km to the south of the campus is the town of Henties Bay, and to the north is the Omaruru Riverbed (river mouth approximately 100 m from the sampling site). The population of Henties Bay ranges between 4 600 and 6 000 inhabitants, according to the Namibia 2011 population and housing census. | ||

Conditions d'utilisation des données | The Principal Investigator(s) of the AEROCLO-sA campaign is Paola Formenti. If you intend to use the following data please contact her by e-mail: paola.formenti@lisa.ipsl.fr. The back-trajectories were calculated by Guillaume Siour (LISA, guillaume.siour@lisa.ipsl.fr). Please consider authorship for both whenever using the data. The LISA (www.lisa.u-pec.fr) is a joint research unit of the CNRS, University Paris-Est Créteil and University of Paris). | ||
