Abstract

The METROCLIMA project currently boasts an extensive network for measuring greenhouse gases and aerosols, which necessitates ongoing maintenance and data management. In addition to the primary measurements, supplementary data from atmospheric dynamics and chemistry models, satellites, and radiosondes are also incorporated. The network comprises five stations dispersed throughout the megacity of São Paulo. The Formulation of an interconnected framework to assess the origins and absorption of greenhouse gas (GHG) in the metropolitan region of São Paulo. Source-tracking using greenhouse gases ratios anding using pollutants: greenhouse gases ratios. Automation of data collection from stations that are connected to the internet and establish an alert system to identify operational failures or interruptions in measurements. Maintenance and automation of data processing, treatment, and analysis. Establishment of equipment calibration routines, particularly for CRDS (Cavity Ring-Down Spectroscopy). Development of protocols for data integration into international networks. (AU)
