Version 3.47 of the Application for Extracting and Exploring Analysis Ready Samples (AρρEEARS) has been released! This release adds data from the Earth Surface Mineral Dust Source Investigation (EMIT) instrument installed on the International Space Station (ISS). EMIT uses an advanced imaging spectrometer to measure the spectrum of light ranging from the visible to shortwave infrared (381 to 2493 nanometers) for each location in an image. This information can be used across several domains to map things like surface mineralogy, vegetation species and health, snow grain size, water quality, dust, and greenhouse gas emissions. AρρEEARS has added the following EMIT datasets:

EMIT L1B At-Sensor Calibrated Radiance and Geolocation Data (EMITL1BRAD v001)
EMIT L2A Estimated Surface Reflectance and Uncertainty and Masks (EMITL2ARFL v001)
Note, while these products will be available for point and area requests via AρρEEARS, results will only be available for download. At this time, the AppEEARS user interface does not support visualizing and exploring of results containing EMIT variables, but this feature will be added in the future.
