NORCE Research AS is conducting a market survey to determine whether there are one or more suppliers capabale of delivering equipment to be used in a research project of measuring grennhouse gases. The purpose of this RFI is to identify: * The technical solutions available on the market * Whether there are viable alternatives to an already identified solution We require two identical systems capable of measuring greenhouse gas exchange (CO₂, CH₄) using the Eddy Covariance method, combined with five automated chambers measuring CO₂, CH₄ and N₂O during the snow‑free season. The equipment will be installed in a remote nature reserve and must support off‑grid power. The Eddy Covariance setup must include an enclosed CO₂/H₂O analyzer, an open‑path CH₄ analyzer, and sensors mounted 2.5 m above the surface. Automated chambers must have a minimum footprint of 0.2 m² and be placed more than 15 m apart. We are also interested in real‑time on‑site data processing. All equipment must be commercially available, and we seek one supplier able to deliver the complete solution. This RFI is not a competition and does not entail any obligations for the contracting authority.
