ECOSTRESS ECO_L2T_LSTE v002 data availability

Hello,
Last month, a new tiled ECOSTRESS product has been released. https://lpdaac.usgs.gov/news/release-of-appeears-version-324/
But as for today, only available data go back to the end of October 2022 (at least over CONUS). What is the schedule for the full archive processing?
Thanks!

Question: Problems understanding MODIS LAI values

Re: Problems understanding MODIS LAI values

Because LAI product is 8bit data type, values are from 0-255. Table 4 of the user guide you provided a link to, says that:
valid range is 0-100, fill values are 249-255, and multiply by scale factor=0.1.
So, mask/filter out values above 100 and multiply by 0.1.
