First Na Lidar Campaign Between Northern/Southern Hemispheres During Spring/Autumn Equinox

Document Type


Publication Date



Exploration of the different results from the Andes Lidar Observatory and from Utah State University are presented to evaluate the Temperature perturbations in the MLT region around the equinox. This last March, a campaign was run between both instruments to take data simultaneously and observe the differences. Some other days close to the equinox was taken into account to get a much better average profile in order to get perturbations out of it. The parameters compared were Density, Temperature and Zonal/Meridional wind which were also put in contrast with physical models like WACCM, MSIS and HWM14 respectively.
