Regional ABI and VIIRS fire Emissions (RAVE)
Regional ABI and VIIRS fire Emissions (RAVE)
Embedded Files
RAVE is a regional biomass-burning emissions inventory. It provides hourly emissions at a spatial resolution of 0.03 degree (~3km) across the conterminous United States (CONUS) and North America.
Emissions are calculated by fusing high-temporal-resolution (5min/10min, 2km) ABI fire radiative power (FRP) and fine-spatial-resolution (375m) VIIRS FRP. ABI FRP is from GOES-East (GOES-16) and GOES-West (GOES-17, will be replaced by GOES-18 in near future). VIIRS FRP is from JPSS satellites ( Suomi NPP and NOAA-20, Suomi NPP will be replaced by NOAA-21 in near future). RAVE emissions products have been validated using carbon monoxide (CO) observations from the TROPOMI on the Copernicus Sentinel-5 Precursor satellite. For a full description of the RAVE algorithm and product validation, please refer to Li et al. 2022.
Product Mission, Status and Distribution
Product Mission, Status and Distribution
Rave product's primary mission is to provide fire emissions to NOAA air quality forecast models in the Environmental Modeling Center (EMC) and Global Systems Laboratory (GSL) in supporting the air quality forecast of the National Weather Service (NWS).
The RAVE algorithm is in transition to NOAA for operation run. Hourly RAVE product is available in near real-time with a one-hour delay at NOAA NESDIS STAR. The near real-time product will be also be available in Amazon Cloud. The science team at South Dakota State University also provides reprocessed RAVE for the CONUS domain.
More information on RAVE product updates and distribution can be found here.
Examples
Annual total dry mass (DM) consumption across the CONUS from April 2020 to March 2021
Annual total PM2.5 emissions across the CONUS from April 2020 to March 2021
Product Applications
Product Applications
Rave product can be used in various applications. For example, it has been successfully applied to forecast air quality across the CONUS by the Community Multiscale Air Quality Modeling System (CMAQ) at NOAA EMC and the Rapid Refresh Forecast System (RRFS) at NOAA GSL.
Application of RAVE in air quality forecast has been highlighted recently by an NOAA feature story. More information on the applications of RAVE product can be found here.
