ACPV - Best practice protocol for validation of Aerosol, Cloud, and Precipitation Profiles

PI: V. Amiridis (NOA)

Start date: 02/02/2023

Duration: 18 months

Funding: European Space Agency (ESA)

Total Budget: 384,999.04 €           IAASARS-NOA Budget: 117,661.20 €

The ACPV project is coordinated by the National Observatory of Athens (ΝΟΑ/IAASARS). It aims at establishing common validation practices for space-based profilers, specifically for aerosol, cloud, and precipitation profiles. It focuses on developing a suborbital data conversion tool for radar, identifying knowledge gaps in validation practices, conducting studies on historical datasets, and promoting the implementation of best practices. The project collaborates with the Implementation Monitoring Group (IMG) and other ESA contracts and seeks to contribute to NASA, JAXA, and EUMETSAT efforts. Ultimately, it aims to provide a validated protocol endorsed as a CEOS best practice.
