The International Soil Moisture Network (ISMN) has been officially accredited by the Global Climate Observing System (GCOS) as a contributing network to the Global Climate Observing System – GCOS Network. This recognition highlights ISMN’s continued commitment to providing high-quality, openly accessible in situ soil moisture data that support climate research and monitoring worldwide.

The GCOS accreditation is granted to observation networks that meet the system’s requirements for data quality, long-term stability, transparency, and open availability — key pillars for reliable global climate observations. By meeting these standards, ISMN strengthens its position as a trusted data provider for the scientific community, space agencies, and operational services that rely on ground-based soil moisture observations for satellite validation, climate model improvement, and water-cycle assessments.

This accreditation reinforces ISMN’s role within the global climate observing landscape and underlines the importance of sustained international collaboration to ensure consistent, high-quality hydrological and climate data for research and decision-making.
