Fallback atmosphere models for lidar measurements without corresponding radio-sounding data and modelling of a local atmosphere profile from historic radio-sounding data: Example of the Sao Paulo lidar metropolitan station

We compare the performance of some available atmospheric modelsfor the atmosphere of Sao Paulo (Brazil) to be used in case of absence of radio-sounding data for the given day. We developed our own model (SPm) from historic radio-sounding data in order to create a local model. By performing inversions of lidar signals (distributed over a year), we could benchmark the performance of the models against radio-sounding data. SPm and ISA-15N show the smallest deviation and represent, therefore, the best fallback models for this southern latitude.
