The surface melting of the Greenland Ice Sheet (GrIS) involves various uncertainties, which are issues to be elucidated for accurate climate projections. To clarify how the atmosphere, snow/ice, and glacial microbes in the GrIS affect the ice sheet change under global warming, the SIGMA and SIGMA-II projects were conducted from FY2011 to FY2019. In parallel, big Arctic research projects such as GRENE and ArCS were also done, which accelerated the Japanese Greenland researches. This paper describes the research results of the SIGMA and SIGMA-II projects as well as the related research projects in the categories of (1) in-situ observations of the atmosphere, snow/ice, and glacial microbes, (2) ice core drilling, (3) satellite observation, and (4) numerical modeling. Furthermore , we discuss current issues in these studies, a linkage to the Cryosphere subject of recently launched ArCS II Project, and the importance of capacity building.","PeriodicalId":331826,"journal":{"name":"Journal of the Japanese Society of Snow and Ice","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115864887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we focus on the surface albedo over snow-covered forests which is suggested probably too high in various global climate models. This study was carried out to verify the occurrence frequency of ice accretion and snow accretion in the boreal forest regions. Using the interval camera installed on the observation tower of 16 m in height at the site located to the north of Fairbanks, Alaska, ice accretion and snow accretion in black spruce forest regions were measured. Based on the results, the surface albedo variation of snow-covered forests and differences in the snow albedo parameterization are discussed to contribute to a better understanding of the role of snow in the climate system. On March 12, 2011, a large earthquake induced rock avalanches in Nagano and Niigata prefecture Japan. These rock avalanches travelled long, about 1 km to 1.5 km sliding on snow with apparent friction angle of 6? to 17.1?. It looks un-common phenomena. Because rock avalanches often stop on snow covering steep slope. We hypothesized that the nature of snow dominate the mobility of the rock-on-snow avalanche, and flew rocks on snow 3.5-m-long slope varying snow hardness, and then we flew a rock and earth of 6 ton on 28-m long snow covering slope. Snow is low friction material but its aggregates is effective cushion by self-deformation, so travelling on normal autochthonous snow cover and mixing snow into the falling material do not contribute such long travelling. However, hardened and consolidated snow provide it because of ice-like low friction and impermeability. The consolidated snow is formed at the contact surface on snow cover by impulsive compressing. Hence, when a falling material plunge into lower thick snow cover, consolidated snow is formed. Then, falling material slide on it by pushing following flow. When the forming consolidated snow basement, water and air are expelled from snow to upper falling material, and they probably reduce friction. As the consolidated snow is impermeable, frictional heat and heart transfer-ring produced snowmelt are kept on the consolidated snow, and it reduce further friction. With downsizing of falling material, the resistivity against forehand snow cover decreases, and it leads to stopping. In addition, with lessening pressure of the falling material to underlying snow cover, forming impermeable consolidated snow stops, and water pressure disappear, and it leads to stopping. Wet and granular snow is likely to be consolidated. Thus these snow covered area and/or season are preferable condition of the long travelling rock-on-snow avalanches. The glacier and mountain permafrost research expedition was carried out in September and October of 2014 in the central part of the Bhutan Himalayas. The aims of this expedition were 1) to make a rock glaciers inventory and identi","PeriodicalId":331826,"journal":{"name":"Journal of the Japanese Society of Snow and Ice","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125045970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
