Empirical orthogonal functions (EOFs) and their principal components (PCs) of tides derived from the JAGUAR-DAS Whole neutral Atmosphere Reanalysis (JAWARA) during September 2004−December 2023

This dataset includes the seasonal cycles of the migrating diurnal tide (DW1), migrating semidiurnal tide (SW2), and eastward-propagating diurnal tide with zonal wavenumber 3 (DE3) at 80−110 km altitude in the mesosphere and lower thermosphere (MLT) region as derived from the tidal analysis of hourly JAWARA temperatures and horizontal wind velocities during September 2004−December 2023. The dataset also includes the first and second EOFs (EOF1 and EOF2) of DW1, the EOF1−EOF6 of SW2, and the EOF1−EOF4 of DE3, along with their corresponding daily PC scores. The data format is NetCDF. The dataset is a supplement to:"Yamazaki, Y., Sato, K., Koshin, D., Liu, H., and Stolle, C. (2025) Empirical Orthogonal Function Analysis of Tidal Variability in the Mesosphere and Lower Thermosphere Based on the JAGUAR-DAS Whole neutral Atmosphere Reanalysis (JAWARA), submitted to Journal of Geophysical Research: Atmospheres."See the above paper for more details about the dataset.
