Description

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 2.3 in Schutte et al., 2024 (https://doi.org/10.5194/wcd-5-733-2024).

Data is split into two files:
1. allyears_NDJFMA_35_75_spectra_v_61d_strato.nc - spectra averaged between 35◦N-75◦N for the stratosphere (10, 50, 100 and 200 hPa) and,
2. allyears_NDJFMA_35_75_spectra_v_61d_tropo.nc - spectra averaged between 35◦N-75◦N in the troposphere (250, 400, 500, 600, 700 and 850 hPa).

The files contain data for November to April (NDJFMA) for years 1979 to 2021.
