NHM-SMAP v1.00 forced by JRA-55 for the Greenland domain

We conduct a near-real time model simulation using the polar regional climate model NHM-SMAP v1.00 applied around the Greenland ice sheet. The model is run in the latest super-computer of the Meteorological Research Institute, Japan Meteorological Agency, and currently forced by the latest Japanese Reanalysis JRA-55. The following figures are updated monthly (basically). If you have any questions/queries, feel free to send an e-mail to the PI of the project: Dr. Masashi NIWANO ("mniwano at mri-jma.go.jp"; change "at" to "@").

Please note we use our own original ice sheet mask developed by Niwano et al. (2018), so the ice-sheet-integrated surface mass balance values are affected by the mask setting.
