Research topics
Dr. Niwano’s current main research interest is to understand the snow-atmosphere interaction in thecryosphere. For this purpose, he performs in-situ meteorological and snow/ice measurements inJapan (e.g., Sapporo, Hokkaido) and the Greenland Ice Sheet (GrIS). He is also well versed innumerical 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 andhis colleagues (the SMAP model is the main outcome of his Doctor Thesis). Recently, he isinterested in the GrIS climate system, and has stayed on the ice sheet for more than 100 days since2012 to conduct field measurements on the atmosphere/snow/ice physical conditions. In 2018, hesucceeded 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 modelinter-comparison projects including ESM-SnowMIP and GrSMBMIP.

Education
