Abstract

LALINET (Latin American Lidar Network) follows its goal to consolidation as a federative lidar network to provide regional coverage over Latin America in providing aerosol and greenhouse gas profiles following QA/QC protocols and promoting the development of researchers and students in atmopheric science field. We show recent results on different approaches for studying the optical properties of the atmosphere regarding aerosols at tropospheric and stratospheric level and greenhouse gas mixing ratio profiles followed by our recent support and validation efforts towards present and future satellite missions.

Highlights

  • LALINET became operational as a scientific network in 2013[1], as a member of GALION (GAW Lidar Observation Network) and covers mostly of South America and Central America

  • Tropospheric aerosols are measured in all stations of LALINET, showing different aerosol type contributions to the sites

  • In the case of coincident profiles of São Paulo lidar and OMPS_LP, the disagreement found was explained by the inhomogeneity of the UTLS aerosol layer [3]

Summary

INTRODUCTION

LALINET became operational as a scientific network in 2013[1], as a member of GALION (GAW Lidar Observation Network) and covers mostly of South America and Central America. The scientific drives rely on observation of aerosol related events such as biomass burnings [2], volcanic eruptions [3], dust transport [4], aerosol-cloud interaction [5], as well GHG mixing ratio profiles [6] and related activities [7]. There are efforts towards an algorithm consolidation following the strategy and goals of a robust. As part of network organization a biannual workshop has been strictly followed in order to improve the network operational ability, to establish new scientific goals, to add more member stations to the network and foster education in atmospheric science
