Validation exercises are required to assess new products or in case of major algorithmic revision. They make full use of available ground-based remote-sensing correlative data and lead to the production of a comprehensive validation report. VAL tasks: - Comparisons against ground-based FTIR measurements (baseline of at least 5 NDACC IR stations, depending on data availability) wp_datasources: - IASI HNO3 profiles provided by ULB/LATMOS - HNO3 FTIR data from selected NDACC IR stations wp_deliverables: - IASI HNO3 validation report End
