Modern ceilometers now have the capability to provide profiles of aerosols including volcanic ash. This new measurement capability of ceilometers, combined with their low cost and high reliability, offers a great potential to enhance the current observation capabilities of aerosols and volcanic ash. E-PROFILE is a measurement program of EUMETNET, the network of European meteorological services, that was initiated by the COST action EG-CLIMET in response to the major Icelandic volcanic eruptions in 2010 and 2011. It is the continuation of the operational radar windprofiler network E-WINPROF which provides vertical wind profiles from 30 European stations and 11 stations located outside of Europe. The objective of E-PROFILE is to integrate the approximately 700 ceilometers and automatic lidars of the 19 member states into a European network providing vertical backscatter profiles for the monitoring of clouds, aerosols and volcanic ash. Initiating this ambitious plan requires that a standardized calibration procedure be developed in collaboration with the COST action TO-PROF to provide aerosol profile information in a homogeneous manner across the network. The measurements will be distributed in real time and a visualization tool of the results on an interactive web page will be developed. We will give a detailed description of E-PROFILE and report on the current state of the development of the network integration and of the retrieval algorithms necessary to monitor clouds , aerosols and volcanic ash.
