This is a publicly available system that allows scientists to search, download and visualize aerosol LIDAR data from the EARLINET network.
EARLINET database includes aerosol backscatter coefficient profiles (as a function of height above mean sea level), together with their errors, mainly at one or more out of the following wavelengths: 355 nm, 532 nm and 1064 nm. In case Raman-lidars are operated, both backscatter and extinction coefficients are provided. Data are stored in Netcdf-Format.
Quality Control procedure on datafile is a useful and needed tool which serves two main groups of users: Data Originator and External users. As concerns EARLINET, the network started its activities in 2000 based on cutting edge lidar instruments for aerosol detection over Europe which agreed on some format of the data and the database was set up in a collaborative way. Going now in the Research Infrastructure path, the set up of automatic QC procedure is a stringent request to be met. The needs of the network were different in different periods, and based on that some QC procedures were set up.
All documentation about the QC actions is reported below.
