Atmospheric ozone remains an important topic especially because of global climate change. In this study, total ozone column (TOC) measurements by a Microtops II (MII) ozone monitor at an urban, tropical site in Brazil are considered with local cloud cover (LCC). The standard deviation (SD) for MII measurements was within 4% averaging 1.14±0.58%. Clouds' presence impacts SD and cloudless sky measurements had SD≤1. The average TOC for the period was 258.0±11.5 Dobson Units. MII TOC data comparison with the Ozone Monitoring Instrument (OMI) showed average differences≤2%. © 2012 Elsevier Ltd.

Abstract
Atmospheric ozone remains an important topic especially because of global climate change. In this study, total ozone column (TOC) measurements by a Microtops II (MII) ozone monitor at an urban, tropical site in Brazil are considered with local cloud cover (LCC). The standard deviation (SD) for MII measurements was within 4% averaging 1.14±0.58%. Clouds' presence impacts SD and cloudless sky measurements had SD≤1. The average TOC for the period was 258.0±11.5 Dobson Units. MII TOC data comparison with the Ozone Monitoring Instrument (OMI) showed average differences≤2%. © 2012 Elsevier Ltd.File in questo prodotto:
