Standard Operating Procedures and Measurement Guidelines for ACTRIS Aerosol column and profile variables

Below is a list of measurement guidelines and the standard operating procedures (SOPs) used for aerosol profile and column measurements within ACTRIS. The SOPs provides guidelines for good measurement practice. The methodologies, guidelines and SOPs are also recommended within EARLINET and GAW.
