Welcome to the Earthdata User Forum! Here, subject matter experts from several NASA Distributed Active Archive Centers (DAAC) can discuss general questions, research needs and data applications. Users can query how to access, view and interpret the data.
The HLS version 1.5 collection has been labeled as provisional because the data products continue to go through incremental product improvements and have not yet been validated for their science quality. These data should not be used in science research or applications. HLS version 1.5 will soon be replaced by a new version that will meet science quality standards. However, by making these provisional data products available, the science community has a unique opportunity to provide feedback on the data prior to a vetted, science quality, data release. Users are encouraged to submit feedback or questions to the LP DAAC User Services or post to the Earthdata Forum.

Do you know if there is any estimated date for when the 'science-quality' dataset will be made available? Also, I see on EarthData that while there is very little provisional data available prior to October 2020, the provisional dataset appears to be complete (every 2-3 days) starting in October 2020. Do you know if the plan is to continue providing this provisional data stream going forward until the new 'science-quality' data is available?

The plan right now is April for the V2.0 science quality stuff and yes they will continue to process up until a release date is set in stone for the provisional stuff. The only caveat being I'm not sure how spotty that might be..................we have had them dump data at one time quite often into our test environment and I would anticipate it may come in like that for a bit. Please let me know if you have any questions.
Adding to @lien's comments... The HLS team and the LP DAAC are targeting a spring 2021 release for the official 'science-quality' S30 and L30 data products. The target timeframe may shift pending science reviews and any changes in production code.
Provisional data streams (S30 currently; L30 beginning ~ January 2021) will continue until the official 'science-quality' data products are made available.
