Description
Basic parameters obtained by the 42m EISCAT Svalbard Radar (ESR). 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/.

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)).
