This particular period is considered herein because the largest biomass burning events are usually recorded during these months. The regional meteorological-chemistry transport model WRF-Chem (version 3.7) was used with the Fire Inventory from NCAR (FINN) fire emissions dataset and aerosol optical depth (AOD) data from the Aerosol Robotic Network monitoring network (AERONET), which has a CIMEL sun photometer located at the Huancayo Observatory, the most important city in the central highlands of Peru. The simulation used a single domain with a grid size of 18 km and 32 vertical levels. Results showed an increase in PM10 con-centrations with an increase in the number of fire outbreaks and AOD during July, August, and September. In contrast, a slight decrease in PM10 concentrations was recorded for October. Further, the meteorological conditions did not favor the occurrence of fire outbreaks in the Mantaro valley during the entire study period; however, an increase in rainfall reduced aerosol concentrations in October. In addition, although the vertical movements prevailing over the central Andes were ascending, they were descending along the Peruvian coast, thus favoring and hindering the dispersion of aerosols in the first and second cases, respectively. Finally, the authors assessed, analyzed, and confirmed the influence of biomass burning on AOD in the studied region. 2020 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56572267005 https://www.redalyc.org/journal/565/56572267005/ https://www.redalyc.org/journal/565/56572267005/html/ https://www.redalyc.org/journal/565/56572267005/56572267005.epub https://www.redalyc.org/journal/565/56572267005/movil 10.20937/ATM.52711 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.1 Vol.33 |
