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 winds during September 2004−December 2023. The dataset also includes the first and second EOFs (EOF1 and EOF2) of DW1, SW2, and 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) Polar Vortex Influence on the Migrating Solar Diurnal and Semidiurnal Tides 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.
