Thanks Tyler!
Just wanna quickly check with you about the status of the AVIRIS-3 keyword. It will be great to have this keyword available soon, so that a few pieces of our work can move on. Thanks!
Best,

Thanks for following up on this Brett and for the clarification from the PI.
I did consider that the interpretation of the bit order should be reversed but that leads to other difficulties in interpretation of the codes. Arguably, this is the most important code as it represents the best quality:
(the bit order must be reversed when interpreting this code)

Despite all 7 band-level bit codes being "0000", indicating "highest quality" and with no atmospheric or adjacency correction, the first two bits are still ..read more

This algorithm returns the near-surface concentration of chlorophyll-a (chlor_a) in mg m-3, calculated using an empirical relationship derived from in situ ...The Chlorophyll Concentration dataset shows global near-real-time concentrations of chlorophyll-a in the ocean. Concentrations are presented in milligrams per cubic meter (mg/m3). Chloro phylls are pigments found in photosynthetic plants that transform sunlight into energy.

It worked finally it just needed the rgb = [665,560,492], also l2gen for MSI is running for version 2022 and 2023, but l2gen for landsat in version 2023 does not running.

Hello,
Could you provide detailed guidance including examples, on how to calculate TECu from realtime GNSS CSV files? I have no idea how to proceed and greatly need assistance with step-by-step instructions.
Thanks in advance.

I am now using this data: GHRSST Level 2P Global Sea Surface Skin Temperature from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the NASA Aqua satellite (GDS2)
(MODIS_A-JPL-L2P-v2019.0).
However, the temperatures I see are freezing temperatures so I was wondering if this is the cloud cover temperature or just errors in the data?
