Automatic lidars and state-of-the-art ceilometers measure continuously cloud base height and aerosol profiles. 

Since 2013, E-PROFILE is working on developing an homogeneous dataset that can be easily used by the scientific community. 
Currently measurements from 80 stations from 13 countries are available. In 2017, E-PROFILE will be able to process data from all instruments in Europe (around 700 instruments).

The instruments are calibrated using algorithms developed in the framework of TO-PROF.

As for now, data are displayed for the previous day. In the near future data will be displayed in real time.
