O conjunto de dados MOD14A1 V6.1 fornece composições diárias de máscara de incêndio com resolução de 1 km derivadas das radiâncias de 4 e 11 micrômetros do MODIS.
A estratégia de detecção de incêndio se baseia na detecção absoluta de um incêndio (quando a intensidade é suficiente para detecção) e na detecção relativa ao plano de fundo (para considerar a variabilidade da temperatura da superfície e a reflexão da luz solar). O produto distingue entre incêndio, sem incêndio e sem observação. Essas informações são usadas para monitorar a distribuição espacial e temporal de incêndios em diferentes ecossistemas, detectar mudanças na distribuição de incêndios e identificar novas fronteiras de incêndios, incêndios florestais e mudanças na frequência ou na intensidade relativa dos incêndios.

The product distinguishes\nbetween fire, no fire and no observation. This information is used\nfor monitoring the spatial and temporal distribution of fires in\ndifferent ecosystems, detecting changes in fire distribution and\nidentifying new fire frontiers, wild fires, and changes in the\nfrequency of the fires or their relative strength.\n\nDocumentation:\n\n- [User's Guide](https://lpdaac.usgs.gov/documents/1005/MOD14_User_Guide_V61.pdf)\n\n- [Algorithm Theoretical Basis Document (ATBD)](https://lpdaac.usgs.gov/documents/87/MOD14_ATBD.pdf)\n\n- [General Documentation](https://ladsweb.modaps.eosdis.nasa.gov/filespec/MODIS/61/MOD14A1)\n\n### Bands\n\n\n**Pixel Size**\n\n1000 meters\n\n**Bands**\n\n| Name | Units | Min | Max | Scale | Pixel Size | Description |\n|------------|-------|-----|--------|-------|------------|------------------------------------|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|\n| `FireMask` | | | | | meters | Confidence of fire |\n| Bitmask for FireMask - Bits 0-3: Fire mask pixel classes - 1: Not processed (obsolete; not used since Collection 1) - 2: Not processed (other reason) - 3: Non-fire water pixel - 4: Cloud (land or water) - 5: Non-fire land pixel - 6: Unknown (land or water) - 7: Fire (low confidence, land or water) - 8: Fire (nominal confidence, land or water) - 9: Fire (high confidence, land or water) ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||\n| `MaxFRP` | MW | 0 | 180000 | 0.1 | meters | Maximum fire radiative power |\n| `sample` | | 0 | 1353 | | meters | Position of fire pixel within scan |\n| `QA` | | | | | meters | Pixel quality indicators |\n| Bitmask for QA - Bits 0-1: Land/water state - 0: Water - 1: Coast - 2: Land - 3: Missing data - Bit 2: Night/day - 0: Night - 1: Day ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||\n\n### Terms of Use\n\n**Terms of Use**\n\nMODIS data and products acquired through the LP DAAC\nhave no restrictions on subsequent use, sale, or redistribution.\n\n### Citations\n\nCitations:\n\n- Please visit [LP DAAC 'Citing Our Data' page](https://lpdaac.usgs.gov/citing_our_data)\n for information on citing LP DAAC datasets.\n\n### DOIs\n\n- \u003chttps://doi.org/10.5067/MODIS/MOD14A1.061\u003e\n\n### Explore with Earth Engine\n\n| **Important:** Earth Engine is a platform for petabyte-scale scientific analysis and visualization of geospatial datasets, both for public benefit and for business and government users.
