Data Access

R04 and R05 CloudSat product data files may be accessed via either direct FTP access or the data ordering interface, which allows for searching by date, granule number, or geolocation.

Data Ordering Interface

    Direct FTP Access

    Files are available from using your website credentials to log in.  If you don't already have an account, create one under the Login link in the main menu above. Data files on the FTP server are organized in the following structure:
    Product.version (e.g., 2B-FLXHR.P2_R04)
    Year (e.g., 2008)
    Day of year (e.g., 007)
    You may use a wget command or a script to simplify access.  A typical wget command looks like the following:
    wget -nd -N -r --user=<your username> --ask-password
    Removing the day directory will result in all 2B-GEOPROF.P1_R05 files for the year to be downloaded. Removing the year directory will retrieve all the 2B-GEOPROF.P1_R05 files for the mission. -nd will cause wget to put all the files into one directory on your computer without the year/day heirarchy and -N will prevent files from being downloaded again when the command is rerun.
    You can also find a Perl script for downloading data on our Software Tools page under the Resources tab above.

    Order Data FAQs

    Q: Why do I get "permission denied" when trying to access my completed order via a web broswer?
    A: Some users have reported this issue when using the Safari browser. Try using Chrome or Firefox instead. They will prompt your for your username and password. 
    Q: I am getting a "421 Error" when I connect to the FTP server. What can I do to solve this problem?
    A: You will need to set your FTP connection to passive. We are running new software, which is causing the need to use passive. On some devices this just involves running the "epsv" command after logging in, before listing or retrieving files.
