EMIT Data Tutorial Series Workshop Open for Registration

EMIT Data Tutorial Series Workshop Open for Registration

Registration Form: [Link]

These workshops are a series that will introduce users to the radiance and reflectance data being delivered from the Earth Mineral Dust Source Investigation (EMIT) mission, currently collecting data from the international space station. While registration is not required to attend, please consider registering so that we can ensure sufficient computational resources are allocated and can better meet your needs.

The workshops will take place from 10-12 Pacific, 1-3 Eastern on February 3, 10, and 17. The webex link for attendance is here and a calendar invite can be downloaded here.
A portion of the workshop will leverage a cloud workspace to execute Python code. This space free and open, but requires authentication via a GitHub username. If you wish to participate in the Python examples, please supply your GitHub username. If you do not have a GitHub account, please sign up here: https://github.com/join
To download data from NASA Earthdata, an Earthdata Login is required. Earthdata login accounts are free and easy to set up. Please create an account at https://urs.earthdata.nasa.gov if you do not have an account already.
