Preparation of multi-stage remote sensing for monitoring sea ice in the Okhotsk Sea with ALOS sensors

In order to develop and/or improve algorithms of extracting various sea ice parameters, such as sea ice concentration, sea ice thickness, and sea ice types from ALOS data, it is necessary to prepare certain data set for verification. This paper describes about the preparation of multi-stage remote sensing for obtaining a series of remotely sensed data of sea ice in the Okhotsk Sea.
