INTERACT-II (INTERcomparison of Aerosol and Cloud Tracking - II)

Following the previous efforts of INTERACT (INTERcomparison of Aerosol and Cloud Tracking), the INTERACT-II campaign used multi-wavelength Raman lidar measurements to assess the performance of an automatic compact micro-pulse lidar (MiniMPL) and two ceilometers (CL51 and CS135) in providing reliable information about optical and geometric atmospheric aerosol properties. The campaign took place at the CNR-IMAA Atmospheric Observatory (760 ma.s.l.; 40.60∘ N, 15.72∘ E) in the framework of ACTRIS-2 (Aerosol Clouds Trace gases Research InfraStructure) H2020 project. Co-located simultaneous measurements involving a MiniMPL, two ceilometers and two EARLINET multi-wavelength Raman lidars were performed from July to December 2016.

All the data from the CIAO lidars, the MiniMPL and from theCHM15k, CS135 and the CT25K ceilometers, operating collocated and simultaneously during the INTERACT-II campaign, are provided here. Additional files for the correction of the MiniMPL incomplere overlap are also provided.

The results of the campaign are described in detail in Madonna et al., 2018 (https://amt.copernicus.org/articles/11/2459/2018/).
