Tenders are invited for H2.2/2022/005 - S5P-FRM4DOAS CENTRAL PROCESSING Tender Action Number: 1-13468 Activity Number: 1000039001 Clarification Request Deadline 14/08/2026 13:00 CET Closing Date Extension Request Deadline 14/08/2026 13:00 CET Announcement Date 22/05/2026 Last Update On 17/07/2026 11:07 CET Update Reason Tender Action Issued MAX-DOAS spectrometers are ground-based remote sensing instruments operating in the UV-visible spectral range and widely used for air quality observations.Through dedicated ESA activities, MAX-DOAS has been incorporated into the Fiducial Reference Measurements (FRM) framework, with the aim of harmonising instrumentation and data processing. This has led to the definition of best practices for instrument operation and the development of a prototype centralised processing system capable of delivering near-real-time data. This system was successfully demonstrated in the FRM4DOAS project.For routine satellite validation, such as for Sentinel-5 Precursor, timely and operational access to high-quality FRM datasets from ground-based MAX-DOAS instruments is essential.Building on the achievements of FRM4DOAS, this activity aims to establish an operational service for the centralised processing of the MAX-DOAS network, ensuring consistent and timely delivery of reference-quality data.
