The NOAA View Data Imagery Portal was designed with educators in mind! Here you will find easy access to NOAA data visualizations pertaining to oceans, atmosphere, land, cryosphere and climate. Depending on the data set you select, daily, weekly, monthly and/or yearly visualizations are available. You can adjust the visualization to view as an animation or view a particular date or time period and by clicking the "data values" box, you can obtain quantitative data for a particular area of interest. For each image, a description with background information and links to related resources is available; images can be downloaded as high resolution images or Google Earth files. A 2 minute video tutorial is available.
