 # Short Description of the Scripts
 
+> **_Note:_** For analysis, we use simulation data of the ionospheric potential through climate models. Since these data are very large (around 350 GB), we only upload preprocessed lower-dimensional data (a few tens of MB) to the repository. Data preparation is possible using the script `0_prepare_data.ipynb`, but this would require downloading large files from https://eee.ipfran.ru/files/seasonal-variation-2024/.
+
 * `1_Earlier_measurements_images.ipynb` plots seasonal variations from external sources
 * `2_Vostok_measurements_images.ipynb` plots seasonal variations and seasonal-dirunal diagram using new and early Vostok PG measurements
 * `3_WRF_T2_images.ipynb` plots seasonal variation of `T2m` temperature averaged across different latitude bands
 * `4_IP_simulations_temporal_images.ipynb` plots seasonal variation of simulated IP grouped by datasets and different year ranges
 * `5_IP_simulations_spatial_images.ipynb` plots seasonal variation of simulated IP grouped by latitude ranges
 
+> **_Note:_** The scripts should be executed sequentially one after another; at the very least, scripts 4 and 5 should be run after script 2. This is necessary because script 2 saves intermediate arrays of preprocessed data from the Vostok station, which are used in scripts 4 and 5.
