Total column ozone content and aerosol optical thickness measurements: instrument performance analysis

Measurements of total ozone content (TOC) and aerosol optical thickness (AOT) at 1020 nm are fulfilled with microprocessor-controlled hand-held ozonometer MICROTOPS (MTOPS) #7351 at the ground-based station at the Institute of Applied Physics since July 2003. It was shown that MTOPS readings are...
