Data contains daily Rossby wave spectra that were obtained from a double Fourier transform, in space and time, and displayed in harmonics with wavenumber n and phase speed c. The underlying dataset for the space-time Fourier analysis is meridional wind of ERA5.

For further details about data, see section 2.2 in Schutte et al., 2024 (https://doi.org/10.5194/egusphere-2023-1877).

Data is split into two files:
1. allyears_NDJFM_35_75_spectra_v250hPa_61d.nc - spectra averaged between 35◦N-75◦N for the troposphere (250 hPa) and,
2. allyears_NDJFM_45_75_spectra_v10hPa_61d.nc - spectra averaged between 45◦N-75◦N in the stratosphere (10 hPa).

The files contain data for November to March (NDJFM) for years 1979 to 2021.
