Retrieval Method
This section covers algorithm flow, cloud clearing, pressure levels and layers, and channel subsets.
Algorithm Flowchart
Description of the CLIMCAPS Optimal Estimation inversion algorithm, a retrieval method to invert hyperspectral infrared radiance measurements into vertical atmospheric profiles.
Cloud Clearing and Cloud Properties
This section describes how cloud clearing affects the interpretation of CLIMCAPS soundings.
Pressure Levels and Layers
Provides detail on CLIMCAPS profile representation and its standard pressure grid. Provides information on pressure levels vs. layers and adjusting profiles to surface pressure. Psuedocode for adjusting boundary layer values is provided.
Channel subsets for AIRS and CrIS
Describes CLIMCAPS channel selection, spectral purity, minimizing interference from other variables and maximizing signal-to-noise.
