The MYD14A2 Version 6 data product was decommissioned on July 31, 2023. Users are encouraged to use the [MYD14A2 Version 6.1](https://doi.org/10.5067/MODIS/MYD14A2.061) data product.The Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) Thermal Anomalies and Fire 8-Day (MYD14A2) Version 6 data are generated at 1 kilometer (km) spatial resolution as a Level 3 product. The MYD14A2 gridded composite contains maximum value of individual fire pixel classes detected during the eight days of acquisition.The Science Dataset (SDS) layers include the fire mask and pixel quality indicators. Known Issues* Known issues are described on the [MODIS/VIIRS Land Quality Assessment website](https://landweb.modaps.eosdis.nasa.gov/knownissue?sensor=MODIS&sat=Aqua&as=6) and in Section 7.2 of the User Guide which covers Pre-November 2000 Data Quality, Detection Confidence, Flagging of Static Sources, and the August 2020 MODIS Aqua Outage.Improvements/Changes from Previous Versions* Refinements to internal cloud mask, which sometimes flags heavy smoke as clouds.* Fix for frequent false alarms occurring 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”.
