                         zero average during the night have been made at the Arecibo 
                         Observatory (Arecibo, PR) and Haystack Observatory (Westford, MA) 
                         optical laboratories for nearly a decade. Recent additions to this 
                         long-term data base include contributions from optical Fabry-Perot 
                         interferometers (FPIs) now in position at the Remote Optical 
                         Facility (Culebra, PR) and at Cachoeira Paulista, Brazil. The 
                         methods for vertical wind retrieval using a single FPI are 
                         reviewed and validated by a bistatic instrument experiment in 
                         August, 2021 using FPI observations from Arecibo and from Culebra 
                         to isolate the vertical wind component in a common volume between 
                         the two sites. Previous climatological evaluation of seasonal 
                         vertical wind behavior from 2015 and 2016 show first standard 
                         deviation vertical wind speed domains in the range of +/- 25 m/s 
                         or more at each observatory, and distinct bimodal peaks in the 
                         upward velocities before midnight and before dawn at Arecibo that 
                         may be tidal. These solar minimum data are compared to the more 
                         solar-active period of 2021 2022. We conclude that vertical 
                         neutral transport is an important dynamical component of the 
                         midlatitude F-region thermosphere.",
