Welcome to the Earthdata Forum! Here, the scientific user community and subject matter experts from NASA Distributed Active Archive Centers (DAACs), and other contributors, discuss research needs, data, and data applications.
I am working on a research project related to ionosphere. I have created a program that downloads the ionex file for a date if I give that date as an input to the program. The issue is that ionex files are normally about 200 kb in zipped form and this program is downloading files of just about 12 kb. So, it is only partially downloading the file. Without this program, I won't be able to proceed in my research project. Please could you help me?
The most common reason for this is that you are not properly passing your credentials to Earthdata login. If you do not pass your credentials properly you are automatically redirected to the Earthdata Login web page. Since you are making an HTTPS request, the server is assuming you are using a web browser and returns the login page. This normally occurs when your .netrc file is missing or in the wrong place, or you have the wrong credentials in your .netrc file. You need to create a .netrc file with your credentials.
