We are currently using a tasseled-cap "Disturbance Index" to map disturbance (click here for algorithm description and list of known issues and here for a data specification/format guide).

Disturbance products are available for:

• WRS2 path 14, rows 32-35
• WRS2 path 15, rows 32-35
• WRS2 path 16, rows 34-35
• WRS2 path 17, row 35
