Geostationary and polar-orbiting remote sensors have different opportunities to observe wildfires. While polar-orbiting sensors have been favoured in wildfire observations, geostationary sensors offer a higher observation frequency. Here, we assess the utility of the Himawari-8 AHI geostationary product and compare it to established polar-orbiting observations from TERRA/AQUA MODIS and SNPP VIIRS for 12 months of fire activity in Australia (2019–2020). Fire Radiative Power (FRP) estimates from AHI (BRIGHT/AHI) are compared to the MODIS (MOD14/MYD14) and VIIRS (VNP14IMG) polar-orbiting products, through varying spatial and temporal aggregations. Results suggest that all products capture similar wildfire dynamics across the continent. For near-simultaneously observed hotspots, the agreement is high between BRIGHT/AHI and the individual polar-orbiting products (r = 0.74–0.77, p |
