alberto_silva_2024 Please find the ASTER scientist further guidance to your questions. Thank you for providing the granule ID. To further address your questions: The ASTER 05 Emissivity Product is distributed as an unscaled uint16 product. To calculate the emissivity per pixel (range 0–1), you need...

@alberto_silva_2024 To better assist you can you provide the granule ID.

@alberto_silva_2024 We have forwarded your questions to the science team to provide some additional assistance with your inquiry. I will follow up with you once I hear back from the science team.
Thank you for your patience.

@alberto_silva_2024 Please find the guidance our scientists provided.
Level-2 products are already in physical units. All you need to do is take the pixel value and multiply it by the scale factor to get the physical measurement.
Let me know if this helps.
