The Micro-sized Microwave Atmospheric Satellite (MicroMAS) with a 12-channel passive microwave radiometer on CubeSat is being developed by Massachusetts Institute of Technology Lincoln Laboratory. These instruments can improve the observation of convective thunderstorms, tropical cyclones and hurricanes.  Through Global Observational System Simulation Experiment (OSSE), the expected impact of adding the MicroMAS on numerical weather forecast models can be assessed. MicroMAS data was simulated with CRTM from the GEOS-5 Nature Run (G5NR) on the low Earth-orbiting platforms and then assimilated into the Global Data Assimilation System (GDAS). An overview of the simulation, validation, and assimilation of MicroMass will be presented
