| Research Abstract |
We have established a new method to identify sea ice floes by X-band Doppler radar under various weather conditions. Using Doppler radar data and sea-ice velocity extracted from the cross-correlation method, we have developed a new matching method to derive high temporal and spatial horizontal distribution of velocity fields of sea-ice. Assimilating these values into Japan Meteorological Agency Grid Point Value (JMA-GPV) data, we have applied our sea ice model for short-term prediction of sea-ice and have compared the results with the Doppler radar data.
