Dr. Niwano is a specialist in the snow-atmosphere interaction in the cryosphere. He has ever performed in-situ meteorological and snow/ice measurements in Japan (e.g., Sapporo, Hokkaido) and the Greenland Ice Sheet (GrIS). He is also well versed in numerical modeling of the snow/ice-atmosphere interaction: The Snow Metamorphism and Albedo Process (SMAP) model, which is a detailed physical snowpack model, was developed by him and his colleagues (the SMAP model is the main outcome of his Doctor Thesis). Recently, he is interested in the GrIS climate system, and has stayed on the ice sheet for more than 100 days since 2012 to conduct field measurements on the atmosphere/snow/ice physical conditions. In 2018, he succeeded in coupling the SMAP model with the Japanese Meteorological Agency’s operational regional non-hydrostatic atmospheric model JMA-NHM and constructed the regional climate model NHM-SMAP. Using these original models by him, he has contributed to several international model inter-comparison projects including ESM-SnowMIP and GrSMBMIP, which will be dedicated for the IPCC reports.

地球の気候システムにおける大気-雪氷相互作用の専門家です。現在は、主にグリーンランド氷床と北海道において、観測的研究と数値モデル研究を強力に推進しています。2018年からは、南極氷床を対象とした数値モデル研究にも着手しました。グリーンランド氷床上には、2012年から現在にかけて、現地観測のために計8回・通算100日以上キャンプを行いながら滞在しております。また、積雪変質モデルSMAP(Niwano et al., 2012, 2014)と極域気候モデルNHM-SMAP(Niwano et al., 2018)のメイン開発者でもあります。日本雪氷学会平田賞受賞(2017年)、日本雪氷学会論文賞受賞(2015年)。
