This is the shared repository for the MAE-GNN reconstructions from radiosonde observations and for the study Pikovnik and Zaplotnik, 2026: Radiosonde-constrained reconstructions reveal a weakening Northern Hadley circulation (available at https://arxiv.org/abs/2503.05331)
For inquiries about the MAE-GNN reconstructions, contact ziga.zaplotnik@ecmwf.int
Detailed instructions how to preprocess reanalysis and radiosonde data, perform the reconstructions, postprocessing, and visualisations is given in: Hadley_cell_analysis/HC_weakening_instructions_for_results_recreation.txt
