First empirical evaluation of the Lozano Closure
The first empirical evaluation of the Lozano Closure focuses on photosynthetically active radiation (PAR), examining whether broadband shortwave transmissivity can be used to reconstruct global and diffuse PAR across contrasting atmospheric and climatic conditions.
The study is currently available as an EGUsphere preprint and is under review for Atmospheric Chemistry and Physics.
Discussion started: 8 September 2026
Public discussion open until: 20 October 2026
