I put this together for my own reference, to avoid the inevitable alphabet soup with an extra sprinkle of: "does that extend to alaska again??". Obviously not exhaustive.

## Fire

#### Monitoring Trends in Burn Severity (MTBS)

MTBS data consists of burn severity and extent information on large fires[^1] across the US from 1984 to the present. Both burn severity and fire extent are derived from Landsat or Sentinel-2 data at a spatial resolution of 30 meters and a temporal resolution of 16 days or so - images are constructed pre- and post-fire to compare Normalized Burn Ratio (NBR) or Differenced Normalized Burn Ratio (dNBR). From there, MTBS depicts severity as a gradient of vegetation response from low (not much vegetation response) to high (potentially complete combustion of vegetation)[^2].
