How are the Level 3 products developed?

The Level 3 products are globally gridded statistical summaries of a range of parameters from select Level 1 and Level 2 products. The Levels 1 and 2 products are in swaths, each derived from a single MISR orbit, where the imagery is 360 km wide and approximately 20,000 km long. At Level 3 the product parameters from multiple swaths are combined to make complete, global maps. The Level 3 products are averages of select Level 2 parameters on daily, monthly, quarterly and annual time scales. The MISR Level 3 Imagery provides easy access to images of select parameters within these products.
