Access HMI, AIA and MDI data with Python

Project description

Docs | Tutorial | Github | PyPI

The drms module provides an easy-to-use interface for accessing HMI, AIA and MDI data with Python. It uses the publicly accessible JSOC DRMS server by default, but can also be used with local NetDRMS sites. More information, including a detailed tutorial, is available in the Documentation.


The drms module supports Python 2.7 and Python 3.4 or newer. It requires the following Python packages:

  • NumPy, version 1.9.0 or newer
  • Pandas, version 0.15.0 or newer
  • Six, version 1.8.0 or newer

The module might also work with earlier versions, but it has not been tested with any versions older than the ones listed above.


If you are using Anaconda, it is recommended to use the conda-forge package:

conda config --append channels conda-forge
conda install drms

Otherwise the drms Python package can be installed from PyPI using

pip install drms

Note: If you do not use a Python distribution, like Anaconda, and did not create an isolated Python environment using Virtualenv, you might need to add --user to the pip command:

pip install --user drms

Running Tests

In order to run any unit tests, pytest needs to be installed.

Basic tests for the currently installed drms package can be run using:

python -m drms.tests

To perform online tests against the JSOC servers, use the --run-jsoc flag:

python -m drms.tests --run-jsoc

To also include additional email verification and JSOC export tests, you need to specify a registered email address, e.g.:

python -m drms.tests --run-jsoc --email
