Dear Staff,
You cal help about the chance to authomatically download from LAADS (or LANCE) system; the VJ02 and VJ03 products released since the last year. Because, I try, by using an unexpired token, to download it and, on LANCE system it's impossible to download the 02 product and, in the LAADS system, both products are impossible to download and, in the MATLAB software give the follow response.

Can you clarify this issue; because seems that these data are yet in a preliminary phase and that are problematic to manage and, as a consequence, it's better not to use for science or other.

Thank you in advance for your patience, work and all; Ikeep in touch

Dear Marco Laiolo:
The Near Real Time (NRT) products (e.g., VJ202MOD_NRT and VJ203MOD_NRT) and standard products (e.g., VJ202MOD and VJ203MOD) are archived and distributed from different servers.

All NRT products are available from https://nrt3.modaps.eosdis.nasa.gov/ (main) or https://nrt4.modaps.eosdis.nasa.gov/(back-up) servers. These (NRT) products are not available from ladsweb, as you are trying to access. So for example, to get VJ202MOD_NRT data you need to go to:
https://nrt3.modaps.eosdis.nasa.gov/archive/allData/5200/VJ202MOD_NRT
More information about NRT data can be found at:
https://www.earthdata.nasa.gov/learn/find-data/near-real-time


All standard products (not NRT products) are available from ladsweb (https://ladsweb.modaps.eosdis.nasa.gov/). So, to access VJ202MOD product go to:
https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/5200/VJ202MOD/

In both cases, you can see wget command or download help to download data at the top of the page.
