Pools of liquid water, called melt ponds, form on the ice during the Arctic summer melt season. A better understanding of sea ice conditions during the Arctic melt season facilitates an investigation of the role of melt ponds in predicting the ice extent of sea ice. Our previous study developed an image analysis method to identify the ice surface conditions into five types (type 1: water only; type 2: ice only; type 3: water and ice; type 4: pond and ice; type 5: water, pond, and ice). However, the method did not used an orthorectified image but rather an oblique-view image and it is difficult to separate the type 5 condition from types 1–4. To resolve this, we have improved our method of image analysis to identify ice surface conditions (particularly type 5) using an orthorectified image. Moreover, we discussed the versatility and future applicability of the improved method.
