The combination of in situ FMC observations, numerical weather prediction (NWP) models, and satellite retrievals has facilitated the development of machine learning (ML) models to estimate 10 h dead FMC retrievals over the contiguous US (CONUS). In this study, ML models were trained using variables from the National Water Model, the High-Resolution Rapid Refresh (HRRR) NWP model, and static surface properties, along with surface reflectances and land surface temperature (LST) retrievals from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument on the Suomi-NPP satellite system. Extensive hyper-parameter optimization resulted in skillful FMC models compared to a daily climatography RMSE (+44%) and an hourly climatography RMSE (+24%). Notably, VIIRS retrievals played a significant role as predictors for estimating 10 h dead FMC, demonstrating their importance as a group due to their high band correlation. Conversely, individual predictors within the HRRR group exhibited relatively high importance according to explainability techniques. Removing both HRRR and VIIRS retrievals as model inputs led to a significant decline in performance, particularly with worse RMSE values when excluding VIIRS retrievals. The importance of the VIIRS predictor group reinforces the dynamic relationship between 10 h dead fuel, the atmosphere, and soil moisture. These findings underscore the significance of selecting appropriate data sources when utilizing ML models for FMC prediction. VIIRS retrievals, in combination with selected HRRR variables, emerge as critical components in achieving skillful FMC estimates.<\/jats:p>","DOI":"10.3390\/rs15133372","type":"journal-article","created":{"date-parts":[[2023,7,3]],"date-time":"2023-07-03T00:49:27Z","timestamp":1688345367000},"page":"3372","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Machine Learning and VIIRS Satellite Retrievals for Skillful Fuel Moisture Content Monitoring in Wildfire Management"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1565-7905","authenticated-orcid":false,"given":"John S.","family":"Schreck","sequence":"first","affiliation":[{"name":"Computational and Information Systems Laboratory, National Center for Atmospheric Research (NCAR), Boulder, CO 80307, USA"}]},{"given":"William","family":"Petzke","sequence":"additional","affiliation":[{"name":"Research Applications Laboratory, National Center for Atmospheric Research (NCAR), Boulder, CO 80307, USA"}]},{"given":"Pedro A.","family":"Jim\u00e9nez","sequence":"additional","affiliation":[{"name":"Research Applications Laboratory, National Center for Atmospheric Research (NCAR), Boulder, CO 80307, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5365-273X","authenticated-orcid":false,"given":"Thomas","family":"Brummet","sequence":"additional","affiliation":[{"name":"Research Applications Laboratory, National Center for Atmospheric Research (NCAR), Boulder, CO 80307, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0634-3648","authenticated-orcid":false,"given":"Jason C.","family":"Knievel","sequence":"additional","affiliation":[{"name":"Research Applications Laboratory, National Center for Atmospheric Research (NCAR), Boulder, CO 80307, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6507-4997","authenticated-orcid":false,"given":"Eric","family":"James","sequence":"additional","affiliation":[{"name":"Cooperative Institute for Research in Environmental Sciences (CIRES), University of Colorado, Boulder, CO 80309, USA"},{"name":"Global Systems Laboratory, National Oceanic and Atmospheric Administration (NOAA), Boulder, CO 80305, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1746-0746","authenticated-orcid":false,"given":"Branko","family":"Kosovi\u0107","sequence":"additional","affiliation":[{"name":"Research Applications Laboratory, National Center for Atmospheric Research (NCAR), Boulder, CO 80307, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0469-2740","authenticated-orcid":false,"given":"David John","family":"Gagne","sequence":"additional","affiliation":[{"name":"Computational and Information Systems Laboratory, National Center for Atmospheric Research (NCAR), Boulder, CO 80307, USA"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,1]]},"reference":[{"key":"ref_1","unstructured":"Congressional Budget Office (2023, June 30).
