Kilpisjärvi Atmospheric Imaging Receiver Array: July 2014

http://kaira.sgo.fi/2014_07_01_archive.html

Thursday, 31 July 2014. Trends 2014 - completed. Trends 2014 meeting was successfully completed. A number of topics were covered. For me personally, the most interesting new information was that the trends affect the space debris population. Hence, we need to follow the foF2 and hmF2 trends. and of course EISCAT and EISCAT 3D space debris measurements are important in this business! Hence, time to travel up to Sodankylä, ETA Friday evening 23 LT! Stopping at London for Th-Fr night). Monday, 28 July 2014.

Kilpisjärvi Atmospheric Imaging Receiver Array: June 2014

http://kaira.sgo.fi/2014_06_01_archive.html

Monday, 30 June 2014. A view to the top of Finland. The highest point in Finland lies near the summit of Halti (Haltitunturi in Finnish; Háldi in Sami), on the Norwegian border in the far north-west of Finland. At a height of 1324m, it is a spur of the mountain whose main summit lies within Norway. The dog, incidentally, is a seven-year old Labrador and also a regular visitor to KAIRA. Posted by Richard Fallows. Sunday, 29 June 2014. No other LOFAR site has such picturesque scenery! Posted by Derek McKay.

Kilpisjärvi Atmospheric Imaging Receiver Array: Achievements

http://kaira.sgo.fi/p/achievements.html

KAIRA is a new facility and so it is yet to realise its full potential. However, already it has accomplished several new innovations. Here we point out a few of the highlights. First all-sky interferometric riometry. Multibeam bi-static plasma parameters. Using KAIRA, the evolution of scintillation from weak to strong scattering regimes has been directly observed in dynamic spectra. "Scintillation arcs", seen previously in two-dimensional power spectra from interstellar scintillation observations, ha...

Kilpisjärvi Atmospheric Imaging Receiver Array: Jänis attacks!

http://kaira.sgo.fi/2014/09/janis-attacks.html

Tuesday, 2 September 2014. Last week we made a service visit to KAIRA. There were four LBA aerials still down from the blizzard of 2014 and these needed fixing. However, on arrival at the site, we noted that there were some other LBA aerials down. We hadn't noticed this in the data, so it must have been recent. And inspection of the field indicated that the nylon lines had been cut on multiple LBA aerials, which is what had caused them to fall. A cut LBA line. (Photo: D. McKay-Bukowski).

Kilpisjärvi Atmospheric Imaging Receiver Array: September 2014

http://kaira.sgo.fi/2014_09_01_archive.html

Friday, 12 September 2014. The KAIRA project has been running for some time now and, like most major scientific instruments, there has been a peer-reviewed reference paper produced which describes the facility, its technical capabilities, its scientific goals and the initial results. We have written this paper and it has been accepted by the journal IEEE Transactions on Geoscience and Remote Sensing. KAIRA: the Kilpisjärvi Atmospheric Imaging Receiver Array - system overview and first results. Posted by ...

Kilpisjärvi Atmospheric Imaging Receiver Array: Data

http://kaira.sgo.fi/p/schedule.html

KAIRA observes continuously, 24-hours a day and all-year-round. The default observation mode is handled by KBT (KAIRA Background Task), unless a special experiment or campaign is scheduled. Applying for time or data. With a few restrictions, it is possible to apply for time on the KAIRA facility or request KAIRA data from other programmes. Any scientists wishing to do so should contact the KAIRA Observer-in-Charge. On published papers unless agreed otherwise. Sep 2012 : Scintillation campaign (ASTRON/SGO).

Kilpisjärvi Atmospheric Imaging Receiver Array: Radars

http://kaira.sgo.fi/p/radars.html

In addition to operating as a passive receiver system, KAIRA is also capable of receiving signals from nearby scientific radars. This page describes the relevant parameters. PLEASE NOTE that KAIRA is an independent facility. Having allocated time on KAIRA does not imply the reciprocal allocation on any of these other facilities. Because the KAIRA system is often used in conjunction with the EISCAT VHF radar at Ramfjordmoen, near Tromsø, the following information may also be useful. Required KAIRA RCU mode.
