This dataset, developed by the California Air Resources Board (CARB), provides spatially explicit, daily estimates wildfire activity, vegetation consumption, and wildfire emissions for all wildfires contained in the CAL FIRE historical fire perimeter dataset from 2015 onward. It includes daily or final fire perimeters and associated emissions data derived from satellite observations (VIIRS), CAL FIRE perimeters, LANDFIRE fuelbeds, and gridMET fuel moisture. Emissions are estimated using the FOFEM model and include pollutants, separated by flaming and smoldering phases. The dataset covers only wildland vegetation and excludes developed and agricultural areas. Fires with multi-day activity are mapped using daily VIIRS-derived perimeters (FEDS), while short-duration fires use final CAL FIRE perimeters. Emissions from FEDS perimeters are scaled to match CAL FIRE fire sizes for consistency. Limitations and Assumptions: 1.) Emissions are modeled, not directly measured. 2.) Fuelbeds and moisture inputs are derived from national datasets and may not reflect local variability. 3.) Smoldering emissions are temporally allocated using satellite fire radiative power, which may not capture all activity after the flaming front. 4.) Wildfire activity for multiday fires is derived from VIIRS (375 m), which is imprecise. |

It supports regulatory, scientific, and public health applications by providing daily estimates of vegetation consumption and pollutant emissions from wildfires. The dataset addresses the need for more precise emissions data to support air quality planning, State Implementation Plans, and exceptional event demonstrations, where linking wildfire activity to air quality exceedances is critical.<br /><br />Disclaimer: This dataset is intended for air quality planning and management purposes only. It is not an operational product and should not be used as an official record of wildfire activity.</td></tr></tbody></table> |
