Riometer data 1994-Entry ID: uk.ac.lancs.dcs-rio_kil_1
Abstract: The Kilpisjärvi IRIS imaging riometer in northern Finland (69.05° N, 20.79° E) is supervised by Lancaster University (UK) and operated in conjunction with Sodankylä Geophysical Observatory (SGO), Finland. It has been in operation since 2nd September 1994. IRIS is funded by the Science and Technology Facilities Council. The site is kindly loaned by METLA, the Finnish Forest Research Institute.
The ... system operates at 38.2 MHz and produces an array of 49 narrow beams with widths between 13° and 16°. The phasing of the array is achieved using an assembly of Butler matrices. The basic scanning interval of the array is one second. For further technical details see the system specifications.
Examples of results obtained from IRIS can be seen on the IRIS highlights page.
