How to get links file for all URLs of ASTER AG100?

by huismichael » Tue Jun 27, 2023 1:30 pm America/New_York

I need to write up a simple program that inputs a URL link and yields the relevant image for AG100. I want to avoid having to download an entire database worth of AG100 h5 files and just pull what I need via URL link.

I notice LP DAAC provides code to access the relevant image if you have the respective URL, and further elaborates that if you so wish you can create "download a Links File (containing URLs to files) from a NASA Earthdata Search Client request for data." I looked at NASA Earthdata for the AG100 ASTER data, and could not find a means of downloading into a .txt or .xml file all the relevant links found in AG100 for every h5 file.

Does anyone know what LP DAAC is talking about with the so-called Links File you can generate from NASA Earthdata Search Client. Or does anyone know of a way to quickly generate a .txt file of all .h5 urls for AG100?
