Abstract content <br> &nbsp; (Max 300 words)

The Radio Interferometric Measurement Equation (RIME) is an elegant mathematical formalism that is uniquely suited for modelling both the direction-independent (DIEs) and the direction-dependent (DDEs) observational effects exhibited by existing radio interferometers (VLA, GMRT, WSRT) and upcoming instruments like SKA and its pathfinders. This paper provides a brief introduction to the RIME and proceeds to discuss how it is being implemented for predicting visibilities from the sky model in MeqTrees, a software package for radio interferometric simulation and calibration.
