DIAGNOSTIC MANDATE & SCIENTIFIC PROBLEM STATEMENT
Atmospheric particulate dispersion and severe winter pollution episodes across the National Capital Region demand rigorous, verifiable ground-truth sensor pipelines combined with vertical boundary layer thermodynamics. VAAYU Lite bridges automated continuous ambient air quality monitoring (CAAQMS) with physical sounding diagnostic models, enforcing strict data completeness validation before forecasting severe air quality excursions.
