The Remote sensing of Trace gas and Aerosol Products (RemoTAP) algorithm is a flexible algorithm that can be used for retrieval of optical and microphysical aerosol properties from Multi-Angle Polarimeter (MAP) measurements, retrieval of aerosol properties and trace gas columns (e.g. CO2, CH4) from spectroscopic measurements, or for joint retrievals using multiple instruments. RemoTAP is …

GRASP
GRASP is a state-of-the-art retrieval algorithm for generating enhanced aerosol and surface products from diverse space-borne and ground-based measurements (Dubovik et al. 2011, 2014, 2021). GRASP retrieval is implemented as a highly advanced statistically optimized fitting of all available observations. For example, GRASP uses an innovative multi-pixel concept in which the fitting is realized simultaneously …

HARPOL
Within the project HARPOL (Harmonizing and advancing retrieval approaches for present and future polarimetric space-borne atmospheric missions), a detailed comparison has been performed of two algorithms for the retrieval of aerosol properties from Multi-Angle Polarimetric (MAP) measurements: the Generalized Retrieval of Aerosol and Surface Properties (GRASP) algorithm, developed at the Laboratory of Atmospheric Optics (LOA) …
SPEX
Accurate aerosol polarization measurements At SRON, together with partners from knowledge institutes and industry, we have developed the SPEX family of instruments for aerosol remote sensing comprising high-accuracy multi-angle, multi-spectral polarimeters. All instruments employ the technique of spectral modulation, invented in the group of Prof. Christoph Keller (Leiden University), to determine the state of linear …
