Re: Request the bi-values needed to calculate LST using the Generalized Split Window (GSW) algorithm with the MYD021KM p
We received your inquiry about the bi coefficients applied in LST retrieval. These coefficients are used to generate high-level MODIS products, which were produced using algorithms developed by MODIS science team members on top of our Level 1B data. We suggest you contact the people in this area as ...

Re: CLDMSK_L2_VIIRS_SNPP_NRT CMR STAC access endpoint
The NRT product is provided by Atmosphere Science Investigator-led Processing System, Space Science and Engineering Center, University of Wisconsin-Madison and not by LAADS DAAC. So, you should find it at:

Re: Delay in publication to s3://prod-lads
Data are posted to ladsweb and AWS almost simultaneously however we found an issue with the file transfer to AWS which is now resolved. However, it will take system sometimes to catch up. We are hoping that VNP46A2 files will be current in AWS in few days (early to mid of next week).

Re: Night Lights for visible Blue Light
No, there is no such product available. VNP46Ax are the only Nighttime Lights (NTL) products available. Please also note that NASA Earth science data are not of a sufficient resolution for viewing small object for example emergency vehicles, individual properties, or similarly-sized features.

Re: download VIIRS data via LAADS by using token
Dear Marco Laiolo: All LAADS systems are working nominally and haven't received any complain from any other users regarding slow data download. Yes, LAADS data are migrated to cloud but that has nothing to do with users' data download. Also, you need to understand that you are accessing data over pu...

We don't have resources to help you with a particular software/tool such as Matlab. You need to consult with the software user support, user guide, or user forum.
