EMIT Mineral Identification and Band Depth and Uncertainty Now Available in AppEEARS!

[LP DAAC - jwilson]

Version 3.62 of the Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) has been released! This release adds a new dataset from the Earth Surface Mineral Dust Source Investigation (EMIT) mission:

EMIT L2B Estimated Mineral Identification and Band Depth and Uncertainty 60 m (EMITL2BMIN.001)
The EMITL2BMIN product was generated to support the EMIT mission objectives of constraining the sign of dust related radiative forcing. Ten surface mineral types are the core focus of this work: Calcite, Chlorite, Dolomite, Goethite, Gypsum, Hematite, Illite+Muscovite, Kaolinite, Montmorillonite, and Vermiculite. Additional minerals are included in the product for transparency but were not the focus of this product. Further validation is required to use these additional surface mineral maps, particularly in the case of resource exploration. Similarly, the separation of minerals with similar spectral features, such as a fine-grained goethite and hematite, is an area of active research. The limits of what can and cannot be separated on the global scale is still being explored. Users are encouraged to read the Algorithm Theoretical Basis Document (ATBD) for more details.

Note, while this product will be available for point and area requests via AρρEEARS, results will only be available for download. At this time, the AρρEEARS user interface does not support visualizing and exploring of results containing EMIT variables, but this feature will be added in the future.

About AρρEEARS

AρρEEARS offers a simple and efficient way to perform data access and transformation processes by enabling users to download only the data they need. AρρEEARS provides access to a wide range of geospatial data from multiple federal archives, including ECOSTRESS, the Soil Moisture Active Passive (SMAP) mission, Daymet gridded weather parameters, ASTER Global Digital Elevation Model (GDEM) Version 3, and population information from the Gridded Population of the World (GPW) collection.

A complete listing of data products available in AρρEEARS can be found on the Available Products list. Additional resources for using AρρEEARS are available on the LP DAAC E-Learning page.
