Basic parameters obtained by EISCAT Tromso VHF radar

2011-09-22 00:00:00

Basic parameters obtained by EISCAT Tromso VHF radar. Data files are distributed in the CDF format by NIPR. The integration time is normally 60 sec or antenna scan time. If you want to use data with the other integration time, you can search them at the website: http://polaris.nipr.ac.jp/~eiscat/eiscatdata/.

The EISCAT data are the intellectual property of the EISCAT Scientific Association. They may be freely used for the purpose of illustration for teaching and for non-commercial scientific research, provided that the source is acknowledged and to the extent justified by the non-commercial purpose to be achieved. Substantial use of these data should be discussed at an early stage with knowledgeable scientists within the EISCAT Scientific Association (e.g., Y. Ogawa (the data representative of Japan; yogawa [at] nipr.ac.jp)). An example of the acknowledgement statement is as follows: "EISCAT is an international association supported by research organisations in China (CRIRP), Finland (SA), France (CNRS, till end 2006), Germany (DFG), Japan (NIPR and STEL), Norway (NFR), Sweden (VR), and the United Kingdom (STFC)."
