The eight months of data acquired by the POLDER instrument have now been processed. This dataset provides daily information on the global distribution of cloud top phase. We present here the results of a statistical analysis of ice and liquid phase occurrence frequencies at the global scale. Temporal variation of these frequencies above land and ocean are analyzed. These results are compared with ISCCP data and the consistency of the POLDER phase product is demonstrated.
