Keywords:Greenland ice sheet, polar meteorology, polar climatology, glaciology, surface mass balance, polar regional climate model

In order to understand the ongoing abrupt changes in the climate conditions around the Greenland ice sheet (GrIS), we have developed the physically based high-resolution (1 hr interval and 5 km horizontal resolution) polar regional climate model NHM-SMAP (Niwano et al., 2018, 2019). Recently, we have conducted long-term climatic calculations from 1980 to 2019 around the GrIS using the model, and submitted the data to the GrIS surface mass balance model intercomparison project GrSMBMIP (Fettweis et al., in review). Now, the data are available for a wide variety of studies around the GrIS. In this contribution, we present available meteorological and snow/ice physical properties from the data, and discuss possible future collaborations using the data.
