Kerguelen (KERG) and Terre Adelie (TERA) stations, France

The French Institute for Research and the Polar Technology (IPEV) located in Brest organizes the polar scientific activity in the French Southern and Antarctic Lands (TAAF). Two neutron monitors are operated by the teams of IPEV in Kerguelen and Terre Adelie, under the scientific responsability of Paris Observatory. Please visit our web site for an overview of our activities.

Several scientific bases exist in the French Southern Lands: Crozet Islands, Amsterdam and Kerguelen and in Antarctic: Dumont-d'Urville (DDU) in Terre Adélie district and Concordia/Dome C, one of the three permanent bases located in the interior of the Antartic continent. The Port-aux-Français base in Kerguelen is located in the Indian Ocean at 50 degrees of Southern latitude and DDU on the Antarctic coast at 66 degrees of Southern latitude. DDU is very close to the south geomagnetic pole (Cutoff rigidity close to 0, lower than any other NM), and thus in the best position to observe solar particules.

Data validation

We send real time data to NMDB for both stations. A basic check is done in real time in order to remove obvious spikes. Once a day the data is checked by our dedicated software (pressure control, ratio between NM sections, etc.) and data is automatically revised (revised tables of NMDB). Once a month a supervised check is operated on the 1minute resolution data and validated 1hour data are produced and sent to NMDB.

Note that for year 2006 to 2010 the 1hour online data for Kerguelen station have not been fully checked.

An effort to include checked historical high resolution data (5min/1min) is ongoing
