The land data is scarce in e.g. the Sahara, but the density over western Europe is pretty high. The land based data is continuous as well, and not affected by cloud cover.
- mturmon 13y agoI think it's a 50km spacing grid over the ocean. There are multiple satellites, so they get multiple scans per day. Also, they might ingest the data into a model, and report the model outputs, so this could enhance temporal resolution. Another issue with in situ sensors is calibration and uniformity. Unless they were installed by a central authority, they are likely to all be different. This makes analysis harder.
