Hemispheric Asymmetry of the Annual and Semiannual Variation of Thermospheric Composition

This dataset includes O, O2, and N2 number densities in the altitude region from 110.1 km to 667.5 km derived from TIMED/GUVI limb observation and the corresponding WACCM-X simulated ones. These data are daily average values in five latitude bins from 50 degree south to 50 degree north with a bin size of 20 degrees, and number of data points and observing local times for the data in the latitude bins. They are used to make Figures 1-10 in the paper with the title the same as the title for this dataset.
