Castillo, Sonia; Patrón, Diego; Alados-Arboledas, Lucas (2024): Monitoring atmospheric pollution, gases and aerosols "online" in Sierra Nevada (October 2022 - September 2023) [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.965430

This dataset presents hourly raw data on gaseous atmospheric pollutants as sulphur dioxide (SO2), nitrogen oxides (NO/NO2/NOx), carbon monoxide (CO), ozone (O3), methane (CH4) and non-methane hydrocarbons (NMHC); and atmospheric particulate matter (PM10) at different locations in the Sierra Nevada National Park (southeastern Iberian Peninsula, Granada, Spain) during the period October 2022 - September 2023. The dataset is derived from two different measurements platforms, one fixed and one mobile. The fixed platform is sited at the Mojón del Trigo Observatory, a high-altitude remote station located in the north side of Sierra Nevada mountain range (SNS, 37.09° N, 3.38° W, 2605 m asl). This station is one of the main facilities of AGORA (Andalusian Global ObseRvatory of the Atmosphere). The mobile measurement platform is a mobile atmospheric observation unit (UMOVIL), that was moving through rural locations with different characteristics, on the south side of Sierra Nevada (ORG, 36.90° N, 3.42° W, 453 m asl; PAM, 36.94° N, 3.36° W, 1134 m asl; CAP, 36.96° N - 3.36° W, 1451 m asl). The dataset was recorded by gaseous and particulate matter analysers. The NO/NO2/NOx analyser (Thermo Scientific, model 42i in UMOVIL and 42i-TL in SNS) is based on the principle of chemiluminescence; the SO2 analyser (Thermo Scientific, model 43i in UMOVIL and 43i-TLE in SNS) is based on the principle of pulsed fluorescence; the CO analyser (Thermo Scientific, model 48i at both measurement platforms) is based on the measurement principle of non-dispersive infrared spectrometry (NDIR); the O3 analyser (Thermo Scientific, model 49i at both measurement platforms) is based on the principle of ultraviolet photometry; the PM10 analyser (Thermo Scientific, model TEOM 1405 at both measurement sites) is based on the gravimetric method for a direct determination of mass particles; and the hydrocarbons analyser (Synspec, model GC955-114 at both measurement platforms) is based on the principle of gas chromatography. The dataset presents hourly mean concentration of each species in micrograms per cubic meter.

Cells with "*" indicate technical errors, whereas empty cells indicate periods of non-operation. The date/time column corresponds to UTC time and refers to the start of the 1h-averaging interval.

The resulting dataset provide valuable information of the concentration of the principal atmospheric pollutants affecting the Sierra Nevada National Park, and can help to establish the pollutant emitting sources with a notable impact on the area.
