Full-resolution animations of Himawari-8 6.2 µm water vapor imagery suggest what a gamechanger Himawari-8 data is, and what a gamechanger GOES-R data will be. Full-disk imagery at every 10 minutes, and at 2-km resolution, means atmospheric motion vectors computed from water vapor imagery (or other channels, such as the 10.35... Read More
