The ESA 3DCTRL project had its official kick-off on the 29th of April 2022. The project end is scheduled for May 2024.

The Handling of 3D Clouds in Trace Gas Retrievals, 3DCTRL study addresses the research subject 2.2.3 “Research on Handling of Clouds in Trace Gas Retrievals” under the ESA Targeted Research Activities for Atmosphere Science Cluster Project – Research Opportunities 2.

The major goals of the 3DCTRL project are (1) to evaluate cloud correction methodologies in Copernicus Sentinel-4, Sentinel-5 and Sentinel-5p trace gas retrieval schemes and (2) to explore ways to improve handling of realistic clouds in the retrievals of atmospheric species.

To reach these goals, 3DCTRL has the following main objectives:

(a) Generate synthetic reference datasets in which true cloud properties including their 3D structure and vertical distribution are known by means of 3D radiative transfer simulations, realistic synthetic data of cloud properties will be obtained from LES model

(b) Explore ways to improve the handling of realistic clouds in trace gas retrievals, specifically for NO₂

(c) Testing and evaluation of improved approaches for cloud correction by application on synthetic and real TROPOMI-S5P data

Publications will appear here.
