TL;DR: An operational nonhydrostatic mesoscale model has been developed by the Numerical Prediction Division (NPD) of the Japan Meteorological Agency (JMA) in partnership with the Meteorological Research Institute (MRI) as discussed by the authors.

TL;DR: In this article, the development of the climate model MRI-ESM2 (Meteorological Research Institute Earth System Model version 2), which is planned for use in the sixth phase of the Coupled Model Intercomparison Project (CMIP6) simulations, involved significant improvements to the representation of clouds from the previous version MRI-CGCM3 (meteorological research Institute Coupled Global Climate Model version 3), which was used in the CMIP5 simulations.

TL;DR: In this paper, the authors describe the Japan Meteorological Agency/Meteorological Research Institute-Coupled Prediction System version 2 (JMA/MRI-CPS2), which was put into operation in June 2015 for the purpose of performing seasonal predictions.

TL;DR: In this paper, numerical simulations of Yamase clouds were conducted using a nonhydrostatic model (NHM) for one month by adopting sponge boundaries widely to lateral grids and upper layers, in order to reproduce a synoptic situation.

TL;DR: The Skyrad pack MRI version 2 (MRI v2) is presented in this paper to retrieve aerosol properties (size distribution, real and imaginary parts of the refractive index, single-scattering albedo, asymmetry factor, lidar ratio, and linear de-depolarization ratio), water vapor, and ozone column concentrations from sky radiometer measurements.
