NASA Earth science data access by ftp has been discontinued and replaced by https. Unfortunately this is not as simple as changing ftp to https in the links and it breaks our current ingest system completely. References to ftp all over the NASA websites are invalid. To access data, you need to make an Earthdata account. You need to be logged in to access the data from a browser, or have API key.

Looking for MOD03

From Earthdata home page

https://earthdata.nasa.gov -> FIND DATA

view all related URL -> documentation http://modaps.nascom.nasa.gov/services/about/product_descriptions_terra.htm

API endpoints -> CMG gives a json looking hopeful https://cmr.earthdata.nasa.gov/search/granules.json?echo_collection_id=C1379767668-LAADS&sort_key%5B%5D=-start_date&page_size=20

which contains urls like https://ladsweb.modaps.eosdis.nasa.gov/archive/allData/61/MOD03/2018/147/MOD03.A2018147.0940.061.2018147150234.hdf which actually work

trying with MODIS/Terra Geolocation Fields 5-Min L1A Swath 1km - NRT https://search.earthdata.nasa.gov/search/granules?p=C1426422512-LANCEMODIS&tl=1511626390!4!!&q=mod03&ok=mod03
