EISCAT database in NIPR

What's new?

3D ion velocity and conductivity data were updated. (August, 2010) New!!
All data (UHF, VHF and ESR) were updated and png files were added to the database. (July, 2010)
New VHF and ESR data were added to this database. (April, 2010)
This top page was renewed. (March, 2010)
Ionospheric conductivity data were prepared and released. (February, 2010)
All analysed data were updated and a problem of the ion velocities offset (see below) was fixed. (February, 2010)
Ion velocities should decrease by 7.0 m/s (for all ESR data) and 3.5 m/s (for all KST UHF data) at all altitudes. (October, 2009)
Summary plots for E-region study were added in the data finder. (July, 2009)
All the data (ESR, KST UHF and VHF) were updated. (July, 2009)
Tromso VHF data after 2000 was updated. (February, 2009)
Lists of KST/ESR/IPY data were added. (February, 2009)
3D ion velocity data were added to this page. The velocity was derived with tristatic method (kst) or monostatic method (tro/esr). (January, 2009)
ESR IPY long-run data were added to the Data finder and ESR data pages. (February, 2008)
Data finder was prepared for the event selection
Kmz files were added to the ESR and Tromso UHF data pages, to plot EISCAT data on Google Earth (Collaboration with Dr. A. Saito in Kyoto University). A movie file is here. (October, 2007)
Realtime pictures of the ESR 32m antenna and Tromso VHF antenna were put on this web page. (September, 2007)
ESR and KST data have been updated since March 2007.
