Knowledge graph centered on CHROMA O₂ A-band cloud retrieval with 32 nodes and 111 connections. Top connected: spectral reflectance, groundwater, Gunnison, radiative transfer modeling, surface albedo.

Description

Bayesian retrieval algorithm using oxygen A-band absorption to simultaneously retrieve cloud top pressure, surface albedo, and cloud optical thickness from four near-infrared spectral channels. Uses Optimal Estimation technique with pre-calculated lookup tables.

Typical Equipment

  • CHROMA algorithm
  • Pre-calculated lookup tables
  • Optimal Estimation framework

Output Measurements

  • cloud top pressure
  • cloud top height
  • surface albedo
  • cloud optical thickness
