I am trying to bulk download MODIS LAI data. In the website they have this message:

In order to serve the Land Processes Distributed Active Archive Center (LP DAAC) user community more effectively, the LP DAAC recently transitioned from FTP to HTTP for ASTER and MODIS downloads.  The HTTP updates are designed to increase performance and improve security during data retrieval.   Users of LP DAAC data should update any automated scripts for LP DAAC data retrieval.

HTTP bulk downloads require different software than FTP.  To download bulk data via HTTP successfully, users should consider the following options for downloading large amounts of data from LP DAAC HTTP servers:

uGet Downloader is available as an Open Source app for GNU/Linux and a portable app for Windows.  More information on uGet can be found by clicking here.

cURL is free and open software that compiles and runs under a wide variety of operating systems.  More information on cURL can be found by clicking here.

Please contact LP DAAC User Services for more information on downloading data via HTTP.

I downloaded and installed the uGet software but I do not know how to actually download the data. Does anyone used this before? How it work?
