Data Identification
    Description: Soil Burn Severity for the Bluewater fire on the Cibola NF. This dataset is based on a differenced Normalized Burn Ratio (dNBR) product generated from Sentinel 2 imagery.
    Fire: Bluewater

Image source: Sentinel 2 MSI
Pre-fire image date:  2017-04-22 
Post-fire image date: 2018-04-17

Processing steps: 
The team processed these data based on aerial and ground observations. Each fire was assessed and corrections to 
the severity thresholds were adjusted independently in order to match the observations and take account for differences
in ground cover and vegetation. The high and low severity classes were underestimated on both fires and the adjustments
made reduced the moderate severity class. The Bluewater data required a greater degree of adjustment to the high 
severity threshold due to differences in stand characteristics. The areas of persistent heat had to be manually revised
on an individual basis. These values were interpolated based on pre-fire vegetation composition as seen in aerial
imagery and lidar canopy data as well as manual nearest neighbor burn severity values.
