How Change Happens


What has kept the Atmospheric Radiation Measurement (ARM) user facility successfully operating over its long history is continually changing in response to evolving science, user needs, and available technology.

Change Starts with Users

Users who have identified a need that they would like to see implemented can effect change within ARM, particularly around:

Because ARM strives to serve the largest number of people, user requests for change are most effective if the buy-in and support of a larger group of ARM users is obtained.

Constituent Groups

ARM prioritizes new needs identified by the ARM’s user community.  Requests for change can happen in many ways. Start by communicating ideas to the most appropriate ARM advisory or support group and working with them to develop the idea to positively impact the largest number of users.

Science Groups

Recommendations for changes to ARM often come directly from external science meetings in the form of:


ARM consciously manages the change process. The coordination of new tasks within ARM is led by Engineering and Process Manager Jennifer Comstock. You can find ARM priorities here.

Instrument mentors often work on the implementation of new instruments. Mike Ritsche leads the process for bringing new instruments into ARM.

Translators work with the scientific community to develop value-added products, or VAPs, from the direct output of ARM instruments. Scott Giangrande is the lead translator.

Data services, ranging from computing resources to resources for reading, writing, displaying, and manipulating ARM data are available through the ARM Data Center, managed by ARM Data Services Manager Giri Prakash.

The Implementation Strategy Team (IST) is responsible for integration and implementation of engineering and development activities and projects that support our operational baseline and providing a vision for future development directions. The IST is responsible to the Technical Director and works closely with the Associate Director for Operations and the leader of the Architecture and Services Strategy Team (ASST).

The Architecture and Services Strategy Team (ASST) is responsible for the representation of and communication with the software development and operations team members. The ARM ASST Lead, Giri Prakash, is tasked to effectively coordinate the participation and contributions of ASST.

LASSO—the LES ARM Symbiotic Simulation and Observation activity—laid the groundwork to produce routine large-eddy simulation (LES) modeling at the ARM Southern Great Plains (SGP) atmospheric observatory. Community input is being sought by LASSO Principal Investigator William Gustafson.
