DEBRA Dust RGB

a published scan loaded here on screen

Dust is coloured by detection confidence over an unmodified background; the Dust RGB is the same scene under the classic recipe, for comparison. Every scan here was produced unattended, from open archives, and nothing on this page is an official product of the agencies below.

Where this comes from

Observations: GOES-19 ABI L1b radiances, NOAA, through NODD on AWS Open Data — open to the public and usable as desired.; Himawari-9 AHI L1b radiances, produced and managed by the Japan Meteorological Agency, distributed freely and openly by NOAA through NODD on AWS Open Data, which is the route this pipeline reads. JMA's own P-Tree channel carries a research-and-education-only condition; it is not used here.
Ancillary fields: Skin temperature: GFS 0.25° TMP:surface, NOAA, through NODD on AWS Open Data.; Emissivity: Borbas, E., Hook, S., Hulley, G., Loveless, M., and Knuteson, R. (2023), Combined ASTER and MODIS Emissivity database over Land (CAMEL) Emissivity Monthly Global 0.05Deg V003, NASA Land Processes DAAC, doi:10.5067/MEaSUREs/LSTE/CAM5K30EM.003. Openly shared under NASA's EOSDIS data use guidance.
Algorithms: DEBRA, the Dynamic Enhancement with Background Reduction Algorithm — Miller, S. D., Bankert, R. L., Solbrig, J. E., Forsythe, J. M., Noh, Y.-J., and Grasso, L. (2017), J. Geophys. Res. Atmos. 122, doi:10.1002/2017JD027365.; Dust RGB — Lensky, I. M., and Rosenfeld, D. (2008), Atmos. Chem. Phys. 8, 6739–6753, doi:10.5194/acp-8-6739-2008, in the EUMETSAT band combination.
Basemap: Coastlines and boundaries from Natural Earth, which is in the public domain, drawn with cartopy. Boundaries are cartographic, not a statement of any position on them.
Software: shachen, an open implementation of DEBRA, run by shachen-operational. Both Apache-2.0.

NOAA data disseminated through NODD are open to the public, and NOAA and JMA request attribution for the data itself. What is published here is modified data — a derived product of this pipeline, not original or unaltered NOAA, JMA or NASA data, and no endorsement by or affiliation with any provider above is implied. Reuse these composites and fields freely with credit to the sources; the observations themselves stay under their own providers' terms.
