What is a Mobile Deployment Platform (MDP)?
Mobile Deployment Platforms (MDPs) are configurable mobile sensor arrays designed for rapid deployment to sites to gather meteorological, water, and soil measurements for Principal Investigator (PI) led research. MDPs are designed for rapid deployment able to capture stochastic ecological events (e.g., fires, flood events, pest outbreaks) across the landscape, as well as the ability to bring NEON standardized measurements to researcher locations.
MDP campaigns may range in duration, but are envisioned to typically range between six months and two years. In essence, each MDP represents a mobile and requestable NEON site designed to collect automated measurements comparable to instrument data collected at NEON field sites (see below for sensor and infrastructure specifics).
The MDPs are not just a suite of sensors, but also a flexible tool by which the community can adapt NEON to their needs by bringing standardized scalable NEON measurement systems to planned or ongoing research projects, experiments, or other existing network sites (e.g., LTAR, LTER).
The MDPs use the same processing algorithms and data QA/QC criteria as standard NEON sites and allows individual research projects to integrate with NEON infrastructure to potentially expand elements of data synthesis and hypothesis testing across the continent.
Potential Use Case Scenarios

Potential use cases for MDP deployment that compliment NEON's existing infrastructure.
Infrastructure and Data Collection Capabilities
Each of NEON’s five MDPs is comprised of a core supporting infrastructure featuring:
- Rohn25G tower that can be configured for various heights up to 100 feet;
- a mobile instrument support hut housed on a trailer;
- a complete trailer-based generator power system;
- capabilities of remote network communications (e.g., cellular network, satellite);
- a configurable array of atmospheric, aquatic and soil sensors; and
- ability to incorporate additional PI instrumentation.
Each MDP unit and its sensors are designed to fit on a trailer, making it easy to transport on roadways. To power the MDP equipment, a given unit may be connected to an available electrical grid or powered by an independent generator system supplied by NEON. MDP sensors are calibrated in the NEON Calibration and Validation Laboratory to collect continuous measurements of a variety of ecological variables.
When a MDP is deployed into the field, it is maintained by a NEON science and engineering team for the duration of the campaign. Data collected from the standard NEON sensors on the MDPs are processed by the NEON project and delivered to the research team. Data collected by PI-provided sensors will still be processed by the PI.

MDP Costs
MDPs are deployed on a cost recoverable basis. PIs interested in incorporating a NEON MDP into their research program will want to plan in advance to include MDP costs in their funding proposals. All PIs who are intending to submit funding proposals which include the MDP should coordinate with NEON Research Support Services to obtain an accurate project specific costing and a letter of support.https://preview.neonscience.org/resources/research-support
Each MDP Deployment is unique in its considerations. If you are interested in an MDP and would like a cost estimate, please contact us at: ResearchSupport@BattelleEcology.org.
Requesting a MDP
Prior to completing the request form for a MDP, all requestors should review the complete information on the NEON Research Support Services page.
MDPs are requested through NEON Research Support Services, which allows researchers to request the use of NEON infrastructure in support of their research programs.
To request a MDP, please complete a MDP Request Form (download link below).
Please use this form for all MDP Research Support requests.
- Submit all MDP requests to ResearchSupport@BattelleEcology.org
- Once the form is received, NEON works with the requester to develop a cost estimate and deployment plan based on the requesters’ needs
All MDP requests undergo a feasibility evaluation by NEON project scientists and staff prior to approval. NEON does not evaluate the scientific merit of requests; this is left to the funding agencies.
As with all of NEON’s Research Support Services requests, the investigators are responsible for providing funding to cover costs associated with each campaign. Research teams often secure such support through grant programs administered by the National Science Foundation and other entities.
Prior to deployment, the requestor is responsible for obtaining all necessary landowner permissions and research permits for the MDP deployment at the site of interest.
