Field Operations and Maintenance of CIMEL Sun Photometers

The contract requires the performance of routine operations, preventive maintenance, and corrective repairs on 36 AERONET CIMEL CE-318N sun photometers stationed at remote National Ecological Observatory Network field sites across the United States. This work involves traveling to geographically dispersed locations to ensure the continuous and accurate operation of these precision instruments used for atmospheric data collection, with an emphasis on maintaining calibration integrity and minimizing system downtime. The contractor must possess the technical expertise to handle sensitive optical equipment in diverse environmental conditions and adhere to strict operational protocols established by NASA. This subcontract, issued under NAICS code 541380, is managed by the NASA Shared Services Center on behalf of the National Aeronautics and Space Administration. The solicitation was posted on April 30, 2026, with a response deadline of May 5, 2026, at 4:00 PM. Performance will take place across multiple U.S. locations without a specified primary site, requiring the contractor to manage logistics for nationwide field operations. The nature of the work demands reliability, adaptability, and a strong understanding of atmospheric sensing technology, with all activities aimed at sustaining the quality and continuity of long-term environmental monitoring data critical to NASA’s Earth science missions.
