HellENIc GeoMagnetic Array
|
|
The National Observatory of Athens operates ENIGMA (HellENIc GeoMagnetic Array), a ground-based magnetometer array in the area of south-eastern Europe (central and southern Greece) for space weather applications. The four (4) existing stations are latitudinally equi-spaced between 30° and 33° corrected geomagnetic latitude and cover the areas of Thessaly, Central Greece and Peloponnese. Each station is equipped with a state-of-the-art vector fluxgate magnetometer. In the near future another station will be installed in Macedonia or Thrace, and there are plans for the installation of an additional station in Crete by mid-2010. One of the primary research objectives assigned to ENIGMA is the study of geomagnetic field line resonances (FLRs).

A fully automated ionospheric station
operates at Pendeli site since September 2000. Users can
access real-time
ionograms with the results of the automatic scaling,
preview some recent ionograms and download daily SAO files
using the SAO
Data Base. For more information visit the Ionospheric
Station Page. |

Satellite Receiving
Stations
|
|
| NOAA/AVHRR IMAGE ACQUISITION
STATION |
The National
Observatory of Athens operates an AVHRR NOAA image
acquisition station manufactured by Telonics Inc.
The receiving antenna is installed at ISARS ('Lofos
Koufou'). Satellite data from NOAA 12, 14,15 and
16 are acquired on a daily basis. Images are archived
(since 1998), pre-processed (radiometric calibration,
navigation, enhancement) and value added products
are produced according to user requirements. |
 |
| SEAWIFS IMAGE ACQUISITION STATION |
ISARS has become
in 2002 an authorized SeaWiFS data user and an authorized direct readout ground
station. HRPT data are capured on a daily basis
with frequency of 1 image per day. Archived data can
be provided to users on demand. |
| METEOSAT RECEIVING STATION |
The Meteosat receiving station
installed at ISARS is a Dartcom PDUS system. Data
in the visible and Near-Infrared as well as Water
Vapour data from the Geo-stationary satellite Meteosat are captured on a daily basis with frequency 2 images
per hour. The images are stored for several days but
are not archived on a regular basis. |
