Semi-quantitative daily surface ozone observations from station Campo-Maior

The dataset consists of a set of semi-quantitative surface ozone observations (hereinafter O3), together with relative humidity observations at the same temporal scales. The dataset consists of daily mean observations from 19 observatories. The daily observations consisted either of one daily observation from a 24-hour strip exposure between 3 PM of consecutive days or two daily observations from a 12-hour strip exposure from 9 AM to 9 PM and 9 PM until 9 AM of the following day. The datasets are from the period 1872 to 1888. They're extensions in times range between 17 and 3 years. The other dataset from the Observatory Infante D. Luiz, the longest semi-quantitative surface ozone observations data series known to date, spans 50 years for daily data (1863 to 1913). For more details see Tables 2a and 2b (Añel et al., 2024). The O3 observations were recovered and manually digitalized from the Annaes do Observatory Infante D. Luiz published between 1863 and 1915 (Fradesso da Silveira, 1863; De Almeida, 1915). The O3 observations were part of the regular meteorological observations conducted at Portugal and former colonies network of meteorological observatories and outstations controlled by the Infante D. Luis Meteorological Observatory (Lisbon), created in 1857 (Raposo, 2017). Geographically the dataset consists of O3 observations between 42°N and 9°S in latitude and 27°W and 15°E. Observatories are located at the Iberian Peninsula and in Africa. Three of those observatories are insular, two at the Azores islands and one at Madeira Island. The O3 observations were conducted using Schönbein test-paper method, also called "ozonoscope". It was based on the color-change of an indicator strip of blotting paper coated with starched potassium iodide. The paper strip was exposed to air between 8 and 24 hours protected from solar radiation and rain. The method applied in the Portuguese observatories was the one from Berigny (1958) who defined the operating procedure, introducing a more precise chromatic scale graduated from 0 to 21 and selected he best quality of impregnated paper. That on was the Berzelius paper manufactured by James a chemist at Sédan (Marenco et al, 1994) that is often referred in logbooks containing measurements as the cale of "James de Sédan". (Añel et al., 2024).
