Protons daily 2024-2025 LT
Proton fluxes observed by the EPT between January 2024 and December 2024 in the southern hemisphere only. In this file, the data was averaged on L (the McIlwain parameter) and in time (daily). The fluxes are thus averaged in bins of L and time.
The dataset has the following structure:
Coordinates
- name - type - size - min - max - description.
- time_center - datetime64[ns] - 365 - 2024-01-01T12:00:00 - 2024-12-31T12:00:00 - center of the time bins.
- time_edges - datetime64[ns] - 300 - 2024-01-01 - 2024-12-31 - edges of the time bins.
- L_center - float64 - 360 - L=1.05 - L=7.95 - center of the L bins.
- L_center - float64 - 361 - L=1 - L=8 - edges of the L bins.
- var_name - str - 15 - Na - Na - name of all variables in the dataset.
Data variables
- name - type - (coordinates) - (size)
- data_mean - (time_center, L_center, var_name) - (299, 360, 15) averaged variables values in the L-Time bins.
- data_std - (time_center, L_center, var_name) - (299, 360, 15) standard deviation of the variable values in the L-Time bins.
