Welcome to the Earthdata Forum! Here, the scientific user community and subject matter experts from NASA Distributed Active Archive Centers (DAACs), and other contributors, discuss research needs, data, and data applications.
We received the following response from the MISR Science Team:
We are testing the L1 software for the new orbit data.
Our current estimate is that the L1 data products will be available in the next few weeks, before the end of February.
You will be informed when we have a specific date when the L1 will become public.
It appears the MISR team is still working to update the MISR L1B Ellipsoid products. On Earthdata Search, the latest file I could find was from October 12, 2022. Someone will post an update here once the data is available.
