# Introduction

As soon as the new dual frequency receivers have been installed on the Plateau de Bure, it has been clear that the atmospheric phase correction method investigated by Michael Bremer at IRAM could be implemented in the interferometer, thanks to the good stability of the receivers: see the May 1995 Newsletter, the Nov. 1995 Newsletter, and the technical reports prepared by M. Bremer.

The purpose of the present document is to describe how the correction method has been implemented in CLIC, for the continuum data, and how the real time acquisition system will be modified to apply the correction in real time to the spectroscopic data.
