The MOD14A1 version 6 product is produced every 8 days, but contains daily information.  The MOD14A1 data file (HDF format) is a 4 dimensional file, which consists of 4 Science Dataset (SDS) layers.  Within each SDS layer are 8 separate files consisting of complete per pixel information for each of the corresponding 8 days.  The SDS layers include the Fire Mask, QA, MaxFRP, and Sample.  The MOD/MYD14 products have achieved stage 3 validation.

 

Improvements/Changes from Previous Versions

• Refinements to internal cloud mask, which sometimes flags heavy smoke as clouds
• Fix for frequent false alarms in the Amazon that are caused by small (~1 km2) clearings within forests
• Fix to correct a bug that causes incorrect assessment of cloud and water pixels adjacent to fire pixels near the scan edge
• Detect small fires using dynamic thresholding
• Process ocean and coastline pixels to detect fire from oil rigs
• The Version 6 Fire Mask has the potential to detect fire over water pixels. Therefore, class 3 pixel values have been changed to be classified as “non-fire water pixels.”
