The dataset contains 13.2 million grid points over Spain/Morocco with VV and VH polarizations, processed by finding the nearest grid points and computing weighted means using a hamming window function with 6.5km radius. Each point stores up to 3000 observations (timestamps, backscatter values, satellite IDs) along with coordinates and cell information.";
