The National Snow and Ice Data Center offers some of our data in the form of images. From these, we have created Google Earth files that enable you to view them on a virtual globe. Our goal is to help people better understand the cryosphere—where the world is frozen—by making our data more visible and interactive. Featured Data highlights some of our most requested data, as well as our newest Google Earth files.
